The Race Tech Shock Rebound Separator Valve, model SMRS 1215000, replaces the stock shaft nut to provide more controlled shock-fluid flow during compression and rebound. This asymmetric valve design helps separate the flow rates for each direction, allowing the suspension to deliver more effective low-speed damping without the overly soft response often associated with the original configuration.
Designed for performance suspension applications, the Race Tech SMRS 1215000 addresses a common issue with stock low-speed rebound adjusters that flow at the same rate during compression and rebound. That shared flow rate can make low-speed damping feel mushy, contribute to bottoming during long-duration hits, and reduce suspension responsiveness. By correcting the flow path, this separator valve helps improve chassis support and maintain a more controlled feel over demanding terrain.
Fitment is intended for compatible shock assemblies that use the applicable stock shaft nut and low-speed rebound adjuster configuration. Verify shock compatibility and installation requirements before purchase. The Race Tech manufacturer part number and vendor part number are both SMRS 1215000. This valve weighs approximately 0.35 lb and is designed as a specialized suspension component for riders, builders, and technicians seeking improved rebound-control performance.
