KW Hydraulic Lift System – makes your super-sportscar suitable for daily use.
Due to the low center of gravity many super cars have less ground clearance. In order to be able to drive over speed bumps or steep ramps in parking garages without any problems, we have developed the KW Hydraulic Lift System. At the touch of a button the HLS system lifts vehicles by up to 45 millimeters allowing obstacles to be negotiated without a problem. Compatible with our KW coilover suspension or with the original suspension depending on vehicle type and application.
KW HLS Lift Kit – Ride height adjustability with more ground clearance at the push of a button
With the KW HLS lift system you can lift your sports car or lowered vehicle to safely negotiate obstacles such as speed bumps, railroad crossings, road construction, garage approaches and underground car parks. Depending on the version of the HLS lift system your vehicle can be hydraulically lifted either at the front axle or at both axles by up to 45 mm. This prevents accidental damage to your aero components, underbody protection or even oil sump. The lift system is available either as a vehicle-specific solution with or without a KW coilover kit, depending on the type of car and the model. If you cannot find your vehicle in our KW HLS product range, our engineers have also developed a universal lift system.
KW HLS systems are available in two different variations. The HLS 2 lift system is only installed on the front axle. The HLS 4 system allows you to lift the entire vehicle. A hydraulic cylinder is installed between spring perch and springs on each of the KW struts. The great advantage of the hydraulic system is that driving dynamics are not affected. The delivery content for all HLS systems include a control unit, which is connected to the vehicles on-board electronics. The vehicle will be automatically lowered at a certain speed to the original level of the KW coilover kit or your factory suspension.
For a wide range of super cars and performance vehicles KW HLS is available as an application-specific solution. Included in the delivery is all the necessary parts for installation including the hydraulic lines & hydraulic pump adapted to your vehicle. All of the components will fit perfectly in your car.

For example, our Street Comfort products allow for a customized ride height setting with mild suspension lowering from 10 - 50 mm, while the Street Performance products allow the maximum technically possible suspension lowering range from 45 - 85 mm, depending on the vehicle. This means that the suspension can be lowered to suit the personal needs of the user and, depending on the product category, a setting ranging from Comfort to Performance can be chosen.
REBOUND ADJUSTABLE TECHNOLOGY
Adjustable Rebound Valve with KW TVR-A (Twin-Valve Rebound Adjustable) Technology.
The rebound stage damping is precisely tuned to the respective vehicle at our in-house drive dynamics test facility, delivered in the middle of the range out of the box. Individual customization can be achieved in 16 precise clicks, allowing you to choose between more comfort or more body control. The two-stage patented TVR-A technology allows the oil to flow through an adjustable, conical low-speed valve during slow piston speeds, while during higher piston speeds the main rebound stage valve opens to handle the flow of large volumes of oil. This provides major improvements in ride comfort without influencing the high-speed.
COMPRESSION ADJUSTABLE TECHNOLOGY (LOW-SPEED)
Adjustable Compression Valve with KW TVC-A (Twin-Valve Compression Adjustable) Technology.
The patented compression valve with TVC-A technology features two separate spring pre-tensioned valves for small and large volume flow. The compression is tuned to the respective vehicle type on our 7-post rig and is delivered in the middle of the range out of the box. With 12 precise clicks the adjustable compression valve can increase or decrease the cross-section in the low speed valve, providing more or less compression damping. In the event of sudden high piston speeds, the low speed spring pre-tensioned needle valve opens to its maximum volume along with the spring pre-tensioned main valve to maximize the volume of oil flow preventing unwanted progressive surges in the high-speed range with its blow-off feature. This makes it possible to support the vehicle body better while still offering more comfort than the conventional valve technology during high wheel travel acceleration. The compression stage damper setting is always supplied in combination with a separate rebound setting, only a truly independent 2-way damper setting allows for true performance optimization.
COMPRESSION ADJUSTABLE TECHNOLOGY (LOW-SPEED & HIGH-SPEED)
Adjustable Compression Valve with KW TVCLH-A (Twin-Valve Compression Low High - Adjustable) Technology.
The compression valve with KW TVCLH-A technology is high-end motor sports technology for the most demanding street and track performance customers. Two separate valves and a two-way adjustable compression valve allow separate compression damping changes in the low and high-speed range. The adjustments are made via two adjustment dials with click increments that feature 16 settings (with 15 clicks) for high-speed and 7 settings (with 6 clicks) of low-speed adjustability. During tuning at the KW driving dynamics test facility, the groundbreaking Variant 4 coilover suspension is tuned to the mid-range setting for the best road performance and provided with an additional recommended setting for occasional track day use. The 3-Way Clubsport coilover suspension is tuned to a mid-level factory setting especially for track day use, with additional range provided for adjusting to a varying degree of vehicle modifications and track conditions. Starting from the factory setting, the damping can be set firmer or softer for low and high-speed. The TVCLH-A technology has a blow-off feature with large cross-section. The resulting amount of low-speed forces create the best support for the vehicle body to keep the tires on the road in the case of wheel-induced high damper speeds (driving over curbs). The separate low and high-speed setting is always supplied with an additional rebound setting, to ensure an independent three-way damper setup.
COMPOSITE SPRING SEAT
Reinventing the way things are done
The KW coilover spring seat, also known as a spring perch, is constructed with a wear-resistant, friction-optimized polyamide composite material encompassing a stainless steel insert. In contrast to the anodized aluminum adjustable spring seats, the polyamide composite material prevents any possible oxidation while the stainless steel insert maximizes strength. In combination with the Inox-Line stainless steel coilover struts, this guarantees the long-term functionality of ride height adjustability.
The Perfect Height-Adjustable Coilover
In comparison to common coilovers, KW uses a friction-optimized trapezoidal thread which is less sensitive to dirt and requires less force to adjust. Its large cross-section also provides a higher load-bearing capacity.
The Truly Permanent Corrosion Resistance
KW’s coilover suspension struts are manufactured from high-quality stainless steel that is rust-proof. In contrast to other solutions, Inox-Line coatings will not wear off while adjusting the suspension making KW coilover struts 100 percent corrosion resistant with an unlimited lifespan. Lowering the suspension using the trapezoidal thread in combination with the polyamide composite spring seat guarantees long term usability. Even after years the ride height adjustability is not affected.
KW Twin-Tube Technology Knows No Limits
The KW reservoirs provide additional oil and cooling capacity for particularly high force systems. The reservoir, which is filled with low gas pressure, can be fitted anywhere and accommodate the adjustable compression valve to provide more working space inside the damper.
7-POST DRIVE DYNAMICS APPROVED
Testing to the Nth Degree
Used regularly by automobile manufacturers and international race teams, KW’s in-house 7-post drive dynamics test facility is utilized to optimally tune KW coilover suspensions according to the design and target group. The 7-post drive dynamics test facility is essential for fine tuning along with actual on-road evaluation on public roads and race tracks. In objective laboratory conditions, which can be reproduced at any time, we work everyday to give our customers the internationally-esteemed KW driving experience.
UNIBAL TOP MOUNT
More Track Performance & Adjustment Options
Depending on the vehicle application, the aluminum unibal top mounts feature a scaled camber adjustment and caster can be optionally adjusted. This means that the camber angle can be set, maximizing the tire contact patch when cornering, making handling even more direct. Please note: increased camber values are only recommended for track day use and may reduce tire lifespan when used on the road.
TECHNICAL COMPONENT REPORT
The technical component report is always included in the package and outlines the guidelines for lowering the suspension of the respective vehicle. The technical component report ensures the vehicle remains useable when set within the guidelines provided in the installation instructions, allowing for an inspection and subsequent entry into the vehicle documents to be carried out without any problems. The technical component report also includes precise vehicle classification, requirements, and tips for safe fitting.These reports are required for road legal approval in many countries, check local laws.
KW TVR-A Technology
Twin Valve Rebound – Adjustable
The rebound stage damping is tuned to suit the respective vehicle at our in-house drive dynamics test facility and comes preset in the middle of the range out of the box. For custom settings the user has 16 precise click positions at their disposal, allowing them to choose between more comfort or more body control.
The two-step, patented TVR-A technology enables the small volume to flow through an adjustable, conical low-speed bypass in the case of slow damper speeds, while in the case of higher piston speeds, the main rebound stage valve opens for the large volume flows. This provides a big improvement in terms of ride comfort without influencing the high-speed range.
OIL FLOW FACTORY SETTING 8 CLICKS
The rebound stage bypass channel is open in a mid-range setting. For slow damper speeds, low oil flows through the bypass in the main valve and the adjustable bypass opening.
The result: a basic setting which conforms to our target parameters for the respec-tive vehicle type and application, and ensures an optimum rebound and deflect ratio.
KW TVC-A Technology
Twin Valve Compression – Adjustable
The patented compression stage valve with TVC-A technology features two separate spring pre-tensioned valves for low and high volume flows.
The compression stage which is tuned to the particular vehicle type on our 7-post rig is supplied with a mid-range factory setting. With 12 precise clicks the adjustable compression stage valve can increase or decrease the cross section in the low-speed valve to achieve more or less compression stage damping. At the same time, in the case of sud-den high piston speeds, the spring pre-tensioned needle valve and the spring pre-tensioned main valve open to their maximum cross section, utilizing the blow-off feature to prevent undesired progressive power surges in the high-speed range. This allows for improved bracing of the vehicle body while simultaneously offering more comfort than with conventional valve technology in the case of high wheel acceleration. The compression stage damper setting is always supplied in combination with a separate rebound stage setting, as only one independent 2-way damper setting allows for true performance optimization.
OIL FLOW IN BASIC SETTING 6 CLICKS
The spring-loaded adjustable bypass valve is open in a mid-range basic setting. In the case of slow damper speeds the small volume of oil flow runs through the bypass valve. The spring-loaded main valve is closed in the case of slow damper speeds, thus enabling additional low-speed compression damping.
Result: optimum, vehicle-specific tuning with very good bracing against rolling and pitching.
KW TVCLH-A Technology
Twin Valve Compression Low High speed – Adjustable
High-end motor sports technology for the most demanding street performance and track performance customers. The 3-way adjustable dampers utilize an independent and separately adjustable 2-way compression valve that enables compression damping changes for both the low and high-speed range. The compression adjustments are made via two adjustment controls on the housing using precise clicks. There are 16 settings for the high-speed range (with 15 clicks) and 7 settings for the low-speed range (with 6 clicks).
During tuning at the KW 7-post Driving Dynamic Test Center, the V4 coilover suspension is tuned so the preset recommended setting for best road performance is in the middle of the adjustment range with an additional recommended settings for the occasional track use. The 3-Way Clubsport coilover suspension is tuned with a preset recommended setting designed for track day use, with an additional recommended setting for the normal highway use. Starting from the factory setting, the damping can be set harder or softer in both the low and high speed ranges. The TVCLH-A technology has a blow-off feature with large cross-sections which allows for a substantial low-speed forces to provide optimum support of the vehicle body without unsettling the body in the case of sudden high damper stimulation induced by the wheels, like driving over apex curbing. The separate low and high-speed settings are always supplied with an additional rebound setting utilizing TVR-A technology for a truly independent 3-way damper setup.
OIL FLOW IN BASIC SETTING 8 CLICKS HIGH-SPEED AND 3 CLICKS LOW-SPEED
KW Clubsport 3-Way Coilover Suspension - Track Setup
KW V4 Coilover Suspension - Street Performance Setup
The low-speed valve is open in the basic setting. At low damper speeds the oil flows through the open bypass. The spring-loaded high-speed pressure disk is closed.
Result: optimum, vehicle-specific tuning with very good bracing against rolling and pitching. The setting enables a good vehicle response to the driving situation. The high-speed valve opens in the case of driving over curbs or expansion joints and allows the deflection of the wheel. The influence of the excitation on the body is reduced, the body remains quieter.
Lift It Up
With KW’s hydraulic lift system (HLS) the body can be raised for more ground clearance with the touch of a button, even while driving. With KW’s HLS, obstacles like speed bumps or steep parking garage ramps can be negotiated easily. The system can be used as a vehicle-specific retrofit solution for OEM dampers or as a complete suspension solution including the hydraulic equipment. The KW hydraulic lift system is available for the front axle or for both axles, depending on the application.
