K-Tech Suspension is pleased to announce its new 35DDS Pro series of high performance Direct Damping System rear shock absorbers! This is the same championship winning rear shock used around the world!

The 35DDS Pro features a CNC machined billet aluminum body and internals, with independent circuits for rebound and compression damping. Each circuit has 32 clicks of adjustment for precise suspension tuning and damping control under any street, track day, or racing conditions. The aluminum body and internals of the 35DDS Pro are hard anodized for great looks and wear resistance. Additionally the 35DDS Pro rear shock offers length adjustment for easy geometry changes, and includes a hydraulic spring preload adjuster for easy sag adjustments. Also included is the K-Tech developed By Pass Valve, adjustment circuit is included to provide precise fluid control under the most demanding conditions (16 clicks of adjustment).

The By Pass Valve (BPV) is an additional unique external adjuster found only on the 35DDS Pro Series rear shock absorber. The BPV adjuster allows oil to flow freely between the two circuits (compression and rebound) at very low velocities. The BPV adjustment feature is not found on any other brand rear shock, and is highly regarded by riders and tuners who have experienced its benefits. This feature would otherwise require additional custom valving (that might approximate the results) and tuning on top of the base cost on competing brands.

The benefit of this BPV adjustment is fine control of initial chassis movements. This can give extra initial support or be used to pick up more side grip, enhancing off corner traction and acceleration. The BPV also allows for quick setup changes for rain or slick conditions.

The BPV adjuster should only be used once you have found the base chassis balance using the correct spring and pre-load.

The 35DDS Pro is fully service-able and rebuildable via nationally recognized dealers and service centers.
