Mopar Performance Hemi Rocker Arms & Components

Product images may differ from actual product appearance.

Mechanical Rocker Arms are made of SAE 1041 forged steel, featuring hardened valve tip pads (to help prevent scuffing) and internal bushings. Can serve as a replacement for original production rockers. Fits both cast iron and aluminum 426 Hemi heads. High ratio rockers may require grinding on block and head for push rod clearance.

Stainless Steel Roller Tip Rocker Arms are made from high-strength, investment grade cast stainless steel and have a roller tip to reduce friction & improve geometry. Designed for drag racing and high strength, they use standard Hemi rocker ratios.
