OEM Rocker assembly that has gone under extensive treatments to improve integrity, reducing common cracking failures, and reducing wear of the part.
Hand removal of casting flash and sharp edges that create stress risers. Special Tumbler micropolishing process for further deburring, removal of surface irregularities, and uniform smooth finish inside and out. This is key for significant reduction in stress cracking.
Ultrasonically cleaned for 100% removal of debris.
VVL pad is removed and chemically treated with Melonite QPQ coating that creates a protective barrier with reduced friction between the cam lobe and the pad. This is key for significant reduction in material transfer that is the common cause of cam/rocker wear in these engines.
Rocker set is shipped assembled and ready to install.
