KW is expanding the program of multiway adjustable racing dampers

With its wide range of racing dampers and complete suspension kits, KW automotive covers numerous application areas for professional Motorsports.

The new solid piston 4-way dampers are also available as KW Competition 5A that features a blow-off feature with 12 clicks of adjustability and lowspeed and highspeed rebound and compression with 18 clicks of adjustability.

Various automobile manufacturers such as BMW, Mercedes, Opel, Porsche, and others rely on the latest developments of the owner-operated suspension manufacturer in their official factory customer Motorsports programs.

Extended range of four-way and five-way adjustable racing shocks

The “KW Competition 4A Inline damper” with its solid piston damping system, it is suitable for all types of non-wheel-guiding axle constructions such as double wishbones or pushrod suspensions.

The 4A Inline damper does not require an external reservoir, as the expansion tank is integrated into the damper housing. The new solid piston 4-way dampers are also available as KW Competition 5A, depends on the axle geometry, which features a blow-off feature with 12 clicks of adjustability and lowspeed and highspeed rebound and compression with 18 clicks of adjustability. This design provides a large achievable force range of 1500N to 12000N and can be tailored to meet the requirements of the customer.

The modular KW valve technology allows specific damping characteristics with the use of various main valves and spring configurations. The low and high-speed valves for the compression and rebound damping are positioned laterally in series and can be precisely tuned and offset with 18 clicks of adjustment. By connecting the valves in series, we achieve a cavitation-free function at a low gas pressure and our development has a precise high-frequency function due to the low valve lift. The entire system ensures low hysteresis and direct response in damping.

Also available for MacPherson strut applications

The KW Competition 4A USD has been designed for racing cars with MacPherson struts and utilizes KW’s inverted mounting design. Our piggyback reservoir can be rotated 360° and if required by the mounting position, the expansion tank can be connected via a stainless-steel braided line.

The valve manifold with its series-connected valves for adjustment in the low and high-speed compression and rebound stages is directly connected to the damper. With our inverted damper design, we achieve a higher stiffness compared to similar dampers with a 30 mm piston rod. Our damper cartridge is made of 25CrMo4 chrome-molybdenum steel and has a diameter of 40 mm.

With all our four-way adjustable shocks, a functional characteristic curve design is possible. Depending on the field of application, we can also convert our solid piston system to a two-way adjustable shock and our racing customers can choose the compression and rebound stages of adjustment in low or high speed.

The KW Competition dampers are designed according to our solid piston design and are also available as cup dampers to take advantage of a cavitation-free function, low hysteresis, high forces and fast response in various brand cups. The characteristic curve is pre-defined, and the valves cannot be adjusted according to the respective regulations to ensure competitive equality.

Further development from GT4 and TCR motor sports developments

The new three-way adjustable KW Competition 3A EXR damper is a further development of the KW Competition 2A EXR damper from the GT4 and TCR motorsports. The damper with external reservoir generates the damper forces at the working piston and at the low-speed and high-speed pressure stage valves in the expansion tank. The gas volume can be adjusted to the damper stroke thanks to the position-independent reservoir.

The EXR damper enables us to work with a lower gas volume than with other systems.

For MacPherson axle geometries, the new 3A EXR upside-down damper has a 40 mm or 45 mm diameter cartridge made of 25CrMo4 chrome-molybdenum steel. The pressure stage valve block in the expansion tank can be rotated; if required by the installation system, a hose connection of the reservoir is also possible.
