The correct length results in proper rocker contact centered on the rocker pad or roller and the correct lifter preload or valve lash per the lifter/rocker manufacturer's procedure.
Full Answer
The correct length results in proper rocker contact centered on the rocker pad or roller and the correct lifter preload or valve lash per the lifter/rocker manufacturer's procedure. Use an adjustable pushrod/checker to simulate the final rod and verify geometry before ordering or installing final pushrods.
