Greddy Rocker Arm Stoppers, allow you to rev higher than stock without risk of kicking off rocker arms. A common problem on SR20's. A finger rests above each of the eight rocker arms if they've began to float and raise then they hit the finger and this keeps them from coming off their seat and causing catastrophic engine failure. - $66.00


Greddy cam gears. These allow more adjustment than the JWT cam gears and are priced to sell. $109.20 each These allow the re-use of your spider gear for the crank angle sensor too!


JGYCustoms Valve Clearance Measuring Service. SR20 Valve trains are hydraulic but they still require the use of shims to keep the rocker arm level on both sides. After a valve job is performed or a new valve is installed these shims must be precision measured and replaced as needed. Failure to do so results in rapid cam and rocker arm wear and possible damage to motor. $100
