Race Tech announces the release of the Shock Rebound Separator Valve (SMRS Series) for Dirt and Street bike models. The Race Tech Shock Rebound Separator valves replace the OEM Shock Shaft Nut with an asymmetric valve that provides a different flow rate in each direction of travel. On standard shocks the Low Speed Rebound Adjuster flows the same for compression and rebound.Testing shows that when the lowest speed rebound damping is quick enough to get good traction, the lowest speed compression damping is too mushy. In Dirt this causes a vague feeling and bottoming on long duration hits like big dips or gullies. For Pavement, Rebound Separator Valve's have the added benefit of pitch control (front to back movement during acceleration and braking). This keeps geometry more consistent.SMRS Series Rebound Separator Valves retail for $49.99.Race Tech products and services are available by emailing firstname.lastname@example.org or call Customer Service at (951) 279-6655.
