Product Overview
Roller rocker arms can reduce sliding contact at the valve tip and change effective valve lift compared with stock-ratio rockers. A 1.6:1 ratio also changes valvetrain geometry and clearance requirements.
Before installing, check stud size, pushrod clearance, spring travel, retainer-to-seal clearance, guide plates and piston-to-valve clearance.
