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, locking nuts and our custom designed steel guide plate cut just for the Shredder head.  Formed from 0.095" steel, making them 37% thicker than standard clone rocker arms that are stamped from 0.060" thick steel. These rocker arms are safe up to .380" 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. Do not use WITHOUT lash caps. Guide plate is cut for 3/16" diameter pushrods. 1/4" will not fit and you will have to open up the slots. The huge and hollow aluminum pushrods should never be used with this guide plate.  Ratio is 1.2:1, so multiply your cam lobe 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 Predator 224 non-hemi 136.5mm deck h
