Set-up made simple

Compression is adjusted at the base of the damper with an easy-to-use clicker, no extra tools required. Rebound is altered via an integrated adjuster at the damper rod, or with the supplied twist wheel where applicable. This lets you quickly tune turn-in, mid-corner support and ride comfort to suit daily driving, fast road or track sessions.

Built to last

Each damper is rigorously tested during production to meet strict quality standards. The stainless construction is rust-free, and the threaded platforms remain operable year after year, so you can maintain your chosen stance and geometry with confidence. When installed by a KW specialist, the Variant 3 kit is eligible for up to a five-year warranty.
