RBS is now stocking the latest rocker arms from Manton to fit Fat head type Hemi cylinder heads that are using Manton rocker stands. This complete hi-ratio intake rocker arm in one affordable package with all the latest improvements and upgrades that a racer could ever want for their Hemi engine.

Rocker arms are made from forged tool steel with a 1.8 ratio and fit all .870" diameter rocker shafts. Intake rocker arms have .570" diameter roller tips with .275" roller pins and are equipped with pressed-in bronze bushing honed to a very precise +/-.0001 tolerance. Rocker arms have weight reduction pockets to reduce weight but not sacrifice strength on high rpm engines with lots of valve spring pressure.

Rockers use a 7/16" adjuster with a 3/8" ball and are made from H-13 tool steel then black oxide finish to give the racer the ultimate in strength and durability. Rocker arm nuts are 1/2" twelve point.

Each rocker arm includes a pushrod adjuster with adjuster nut. Rocker arms are sold each. Tool steel rocker arm is shown in the pictures.
