Heavy Duty 1.2:1 Steel Rocker Arm Set for GX200 and Small Block Clones Including Shredder

These are the same 1.2:1 ratio HD stamped steel rocker arms included with all of our Shredder heads. Comes with steel rocker studs, lash adjusters, and locking nuts. 

Formed from 0.095" steel, making them a full 50% thicker than standard clone rocker arms that are stamped from 0.060" thick steel. 

These rocker arms are safe up to .400" valve lift, but the lower opening can be ground on the valve side (not pushrod side) from .350" to .390" total length and they will support up to .450" lift without binding..  

Ratio is 1.2:1, so multiply your cam lift by 1.2 to get your net lift at the valve. 

Example: .308" x 1.2 = .369" lift with these rocker arms. 

Use 5.260" pushrods for non-hemi block with Shredder or other inline valve head.

Use 5.200" pushrods for hemi block with Shredder or other inline valve head. 

Not for use with hemispherical heads. Sold as a set of two.
