Description
Stock shock damping feels vague and unpredictable during aggressive driving because compression and rebound flow rates are identical—leaving your suspension mushy and prone to bottoming. The RACE TECH Shock Rebound Separator Valve SMRS 1215000 replaces your factory shaft nut with an asymmetric valve that decouples these flow paths, delivering precise low-speed damping control and a responsive, planted feel through long-duration hits. If you’re serious about suspension tuning and consistent lap times, this is the upgrade that bridges the gap between stock geometry and truly dialed-in performance.
