The K-Tech DDS "Pro" rear shock has been designed for use at the highest level of racing and developed in major championships around the world. Like all other K-Tech products it has been designed and manufactured in the UK using the latest design software and highest grades of materials. As you would expect from a high quality racing product, the DDS "Pro" features compression and rebound damping adjustment, length adjustment and hydraulic spring preload adjustment. It also features our unique ByPass Valve adjuster which controls both compression and rebound damping adjustment to assist with chassis control at low velocity shock movement to enhance tyre feel and grip. The DDS system uses a smaller piston rod which keeps the system more stable over a wider temperature range due to its small displacement. Damping is controlled by a 32mm piston which allows the use of larger shims for improved feel.
