Tomei Rocker Arm Stopper — SR20DE(T) — TA311A-NS08A
The Tomei Rocker Arm Stopper (RAS) is a proven valvetrain upgrade designed for SR20DE and SR20DET engines. At high RPM, aggressive driving, or during over-rev situations, the SR rocker arm can deflect or jump, which may lead to serious engine damage. The Tomei RAS helps control rocker movement by stabilizing the lash adjuster side of the rocker arm, reducing the risk of rocker arm failure during high-load operation.
