The K-Tech DDS "Pro" shock absorber has been developed for use at the highest level of racing and has been further developed in the major championships worldwide. Like all other K-Tech products, it has been designed and manufactured in the UK using the latest design software and the highest quality materials. As you would expect from a high quality racing product, the DDS "Pro" has adjustments for compression and rebound damping, length adjustment and hydraulic spring preload. It also features our unique ByPass valve adjuster which controls both compression and rebound damping adjustment to improve chassis control at low speeds of shock movement and optimise tyre feel and grip. The DDS system uses a smaller piston rod which makes the system more stable over a wider temperature range due to the lower displacement. Damping is controlled by a 32mm piston which allows the use of larger schims for improved feel.
