What is the iLIFT® system?
The iLIFT® system is an Intelligent Vehicle Suspension Lift System that raises the vehicle to avoid damage from contact with speed bumps, steep driveways and other obstacles.
How is the iLIFT® system different from other lift systems?
High Performance – The iLIFT® system has better performance relative to many competing systems.
Activates/deactivates in less than 1 second.
Provides up to 3.5” of lift.
Intelligence – The iLIFT® system monitors the ground clearance with sensors and automatically activates the system – it is the only system on the market with such capability and the company has a patent on the use of sensors in such applications.
Preservation of vehicle performance - The actuator assembly measures only ½ inch thick at the top of the suspension spring and allows use of longer springs than competitors.
Easily fitted into existing suspension systems - Compact actuator design and low thickness at the top allows fit into more OEM suspension systems than competing products.
Reliability – the iLIFT® system has been designed to be maintenance free and to have much higher reliability than competing systems.
Maintenance free – the iLIFT® actuator is protected from contaminants and has a number or other proprietary durability-enhancing features.
High-quality materials/components such as aerospace grade material.
Air filter system prevents water buildup in the air tank and possible fluid backup in air lines.
What makes the iLIFT® system “Intelligent”?
The iLIFT® system uses a sophisticated and Patented Electronic Control Unit (ECU). The ECU is the “brains” of the iLIFT® system. It integrates with the vehicle's existing electronic systems and it monitors various parameters such as ground clearance, vehicle speed and system air pressures. It responds to commands of the driver and/or the automatic sensors to raise and lower the vehicle.
The driver can customize the iLIFT® system to desired preferences with over 25 different iLIFT® features. This customization is accomplished by simply selecting options with DIP switches located on the ECU.
Who is the iLIFT® system intended for?
iLIFT® systems are for people who drive cars that are low enough to contact obstacles such as speed bumps and steep driveways.
People who drive exotic cars or cars that are low to the ground.
People who want to lower their vehicles in order to improve the performance, handling, fuel economy and appearance of their cars without worrying about potentially damaging their vehicles.
People who may have difficulty entering or exiting their vehicles, such as individuals with certain disabilities or chronic back pain.
People who drive race cars and want to set the ride heights of their cars as low as possible for improved performance on the track and still be able to drive their vehicle in street conditions.
Drivers looking for an advanced, high quality, and automated lift system.
Will the iLIFT® system affect the performance of the car’s suspension and handling?
The iLIFT® system does not affect the performance of suspension during normal driving. iLIFT® cylinder assemblies are installed on the coilover so that they normally act as a fixed “spacer” that does not affect the performance of the shock absorber or the handling of the vehicle. With the iLIFT® system you are NOT "riding on air" and the suspension's performance is maintained. When activated to raise the vehicle, iLIFT® cylinders extend fully to raise the vehicle to go over obstacles. Once the obstacle has been passed they return to the lowered "normal" driving position.
The iLIFT® system adds ZERO unsprung weight to the vehicle to preserve the suspension's high performance.
The iLIFT® cylinder and piston assemblies that raise the vehicle are mounted at the top of the coil spring. Each cylinder and piston assembly weighs less than 2 pounds.
How much will an iLIFT® system raise a car?
The iLIFT® system provides up to 3.5” of lift in under 1s (depending on the car’s weight)
How fast does an iLIFT® system raise a car?
The iLIFT® system can raise the front of a car in less than 1 second. The actual time depends on the weight of the vehicle, the settings of the ECU and the installation of the system. Lighter cars generally rise a bit faster than heavier cars.
The iLIFT® system with front and rear lifting option typically raises the front of the vehicle first, followed by the rear. This is done to raise the front of the car quickly since the front of the car will encounter the obstacle first. The rising of the rear of the car typically follows within one second or less.
How much weight can the iLIFT® system lift?
Each cylinder and piston assembly is capable of lifting over 1,500 pounds. A Front + Rear iLIFT® system option is capable of raising a vehicle weighing over 6,000 pounds. Most high performance vehicles using the iLIFT® system weigh less than 4,000 pounds.
The iLIFT® system is user configurable to raise vehicles of various weights. The ECU can be configured to match the iLIFT® system’s lifting power to the vehicle's weight at the front of the vehicle and at the rear of the vehicle.
Will the iLIFT® systems fit all vehicles?
iLIFT® systems use compact components that makes it easily fitted to most vehicles.
The iLIFT® systems use Actuators (cylinder and piston assemblies) that are installed on the top of the suspension's coil springs. These assemblies measure 4.75 inches in diameter by 3.3 inches in height. The vehicle needs to have enough space to accommodate the Actuators at the top of the coil spring.
iLIFT® Actuators fit onto the top shaft of coilover suspension. The iLIFT® Actuators may add approximately ½ inch to the top of the suspension's coil spring. The actual amount will vary depending on your suspension and the type of top mounts used.
Coilover suspensions usually have an adjustable bottom perch to allow adjusting the ride height of the vehicle. In most cases the coilover will have enough height adjustment to allow using the existing coil springs. • The iLIFT® actuator fits most brands of coilover suspensions with the following shock absorber shaft/rod diameters: 12mm, 12.5mm, 13mm, 14mm, 15mm, 16mm, 18mm, 20mm and 22mm.
The iLIFT® system has been fitted to the following coilovers: KW Club Sports, KW Variant 3, JRZ, BC Racing, Buddy Club, Ohlins and others.
The iLIFT® system is compatible with suspension springs with the following inner diameter sizes: 60mm to 65mm.
iLIFT® systems may also be fitted to vehicles with independent coil springs that are separate from the shock absorbers/dampers.
How are iLIFT® air tanks different from the air tanks on competing systems?
The air tanks used in the iLIFT® system are custom designed to meet our high standards of safety and efficiency. Our air tanks are significantly smaller and stronger than those used by competing lift systems, where often basic, off-the-shelf air tanks are used. Each iLIFT® air tank is made in America and constructed out of a 6061 Aluminum. Each air tank is individually tested to over 1,000 psi, a 5x safety margin, before being approved for use in the iLIFT® system.
Why are there multiple sizes of air tanks?
We offer air tanks in these 3 sizes: ½ gallon, ¾ gallon and 1 gallon.
Smaller tanks offer a greater ease of mounting in vehicles with limited space.
Larger tanks provide larger capacity for front and rear lift systems and for heavier cars.
The ½ gallon tank measures 4-3/4 inches by 9 inches and is suitable for Front Only iLIFT® systems that don't have enough space to accommodate a larger tank.
The ¾ gallon tank measures 4-3/4 inches x 14 inches and is suitable for all Front Only iLIFT® systems and for Front + Rear systems on vehicles weighing up to 3,300 pounds.
The 1 gallon tank measures 5 inches x 14 inches and is normally used for Front + Rear lift systems on heavier cars weighing over 3,300 pounds.
Using larger tanks will provide additional reserve capacity with an increase in lifting speed.
Smaller tanks are easier to mount in some vehicles with limited space.
What type of air compressor is used by the iLIFT® system?
The iLIFT® system is very efficient and was designed to operate with a smaller compressor than other pneumatic lift systems.
The small air compressor weighs 3.5 pounds.
The small compressor weighs 5 pounds less than the large compressor and is also smaller in size. The small compressor is often the only choice when vehicles have limited space.
The smaller compressor is recommended for front only option or for front and rear option on lighter vehicles.
The larger air compressor weighs 8.5 pounds.
The large compressor is recommended for front and rear options that will experience heavy use or if they are used on heavy vehicles.
Can a vehicle equipped with the iLIFT® system go over multiple obstacles such as speed bumps in a parking lot or multiple ramps in a parking structure without running out of air from such a small air tank?
Yes it can. However, when encountering multiple obstacles such as ramps in a parking structure the system can be commanded to rise by pressing the UP button. It will then remain raised until all of the obstacles have been passed.
The vehicle can be set to stay raised until the system is deactivated or once the vehicle speeds up to a set speed (generally 20-25 mph). The iLIFT® system provides an audio reminder at 30 second intervals when the vehicle is in the raised position.
What happens if the driver raises the car and forgets to lower it?
The iLIFT® system is intelligent and doesn’t forget. When the vehicle is in the raised position, the iLIFT® system provides an audio reminder at 30 second intervals. When the vehicle is raised, the iLIFT® system will automatically lower the vehicle when it reaches the maximum speed set by the owner in the ECU (generally 20-25 mph).
What is the Maximum Speed setting on the ECU for?
The maximum speed setting is used to automatically lower the vehicle if it is raised and the vehicle reaches the maximum speed selected and entered into the ECU. The maximum speed is also used to prevent the vehicle from raising if it is traveling faster than the maximum speed selected. We recommend setting a Maximum Speed between 20 and 25 MPH. The maximum speed is faster than typical driving speed over obstacles such as speed bumps. If the driver manually raises the vehicle to go over an obstacle, the iLIFT® system will automatically lower the vehicle for normal driving once the maximum speed is reached.
What does an iLIFT® system weigh?
A complete iLIFT® system can weigh as little as 16 pounds. This is for a front only system with a small compressor. Adding the rear lifting capabilities will add approximately 5 pounds. The small air compressor weighs 3.5 pounds. Using a larger compressor that weighs 8.5 pounds would add 5 pounds of weight compared to the small compressor.
What sizes of suspension coil springs are compatible with the iLIFT® system?
The iLIFT® system is compatible with coil springs having inside diameters of: 60mm, 62-63mm and 65mm.
Does installation require a change of coil springs?
The iLIFT® system was designed to add a minimal height to the top of the coil springs in most applications. In most cases the iLIFT® cylinder assembly adds around ½ inch or less to the top of the spring. This is normally offset by simply lowering the bottom spring perch or adjusting the shock absorber mount. In some cases, where the coilover uses the top mounting plate as the top spring perch, it is sometimes necessary to use shorter springs if the bottom spring perch can't be lowered adequately.
In many cases the springs supplied with the coilovers can be used.
To achieve the maximum lifting capability from the iLIFT® system, the suspension springs should compress at least 2 inches from the weight of the vehicle. If the vehicle uses very stiff springs that do not compress at least 2 inches from the weight of the vehicle it may have less than maximum lift. Most coilover suspensions can be upgraded with the addition of "Softer Helper Springs" to provide extra suspension travel and fully utilize the lifting capabilities offered by the iLIFT® system
What are the differences between the Automatic iLIFT® system and the Manual iLIFT® system?
The Automatic iLIFT® system utilizes sensors under the vehicle to monitor ground clearance and automatically raise the vehicle without a driver’s input. [The Front only Automatic systems uses four sensors installed below the front lip of the vehicle. Front + Rear Automatic systems use two additional sensors mounted under the sides of the vehicle between the front and rear tires.]
A Manual iLIFT® system requires the drivers to press a button to raise the vehicle; the car can be configured so the driver can use the vehicles existing cruise control buttons, a dedicated, aftermarket switch, or a remote control. An Automatic System will also have this functionality to allow a driver to activate the system manually.
Why would a driver want a Front and Rear system option versus a Front Only iLIFT® system option?
Front + Rear options are more versatile than front only options. They will raise the center of the vehicle more than a front only option. This is beneficial for vehicles that are low and may get damaged including scraped going down steep ramps with abrupt transitions. Front + Rear options will also raise the rear of the vehicle to protect the rear and items such as tail pipes and diffusers. When the front only is lifted, the rear of the car actually “squats” a bit. It becomes lower. This is not normally a problem but if the car is extremely low, raising the rear will greatly reduce the chance of scraping the rear and the center of the car. Front + Rear option gives the drive versatility of raising only the front or raising the front and rear.
A Front Only option is suitable for vehicles that have adequate ground clearance in the center and the rear of the vehicle. Most of the damage is caused by scraping against obstacles at the front lip. A Front Only option will address the front scraping. Front Only option will raise the center of the car less than a Front + Rear option will.
What does the Electronic Control Unit (ECU) do?
The main function of the ECU is to monitor the ground clearance and automatically raises and lowers the vehicle to avoid damage on obstacles
The ECU has many other functions including: monitoring air pressures, monitoring vehicle speed, monitoring the vehicle's cruise control system for manual commands from the driver, raising and lowering the vehicle, controlling the compressor, and providing audio indications to the driver notifying of system status.
The ECU is highly configurable by the driver to match the vehicle and the driver's preferences.
How is the ECU customized to a specific vehicle and to driver’s personal preferences?
The ECU is customized by using the DIP switches on the ECU to select the parameter to be customized, then pressing the button on the ECU to make your selection.
What iLIFT® parameters can an owner adjust with the ECU?
The ECU can be customized to match the vehicle's front and rear weights, adjust the lifting speed, select the mode of operation such as: Fully Automatic, Semi-Automatic / Manual and OFF, customize the button presses and response time to the driver’s preferences, customizing the audio feed back. Even the pitch of the audio indicators is adjustable.
There are over 25 different parameters that can be customized with the iLIFT® ECU
How long does it take to install an the iLIFT® system?
The installation time depends on the system configuration selected, the experience of the installer and the specific vehicle.
Actual installation times will vary depending on the installer, their experience and the specific vehicle. Most iLIFT® systems are pre-mounted on either a universal mounting board or a custom, vehicle-specific mounting board to simplify the mounting of the compressor, filter, air tank and valve manifold.
An installation of the iLIFT® system by an experienced automotive export can take as little as 4 hours for a Front Only Manual system, to as much as 12 hours for a Front + Rear, Automatic system, depending on the type of vehicle.
What are the options for mounting iLIFT® Air tanks and compressors?
The iLIFT® air tank, valve manifold, air filtration system and compressor can be pre-mounted on an aluminum Universal Mounting plate for easy mounting. These universal systems may either be “floor mounted” such as on the floor of a trunk, or “wall mounted” such as on a vertical wall of a trunk. With the universal mounts there is a choice of 2 different sizes of air compressors and of 3 different sizes of air tanks.
The individual components may also be removed from the mounting plate and individually mounted in the vehicle for a “custom” installation.
Vehicle Specific Pre-Mounted Systems:
The iLIFT® system also currently has specific mounting configuration for Acura NSX. This application-specific iLIFT® system greatly reduces the labor required and fits the car “like a glove”. For the Acura NSX there are three custom mounting options: right rear fender, left rear fender, left trunk wall.
