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 By-pass 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.
