1.6 Ratio Shaft Mount Roller Rocker Arms

The Harland Sharp CSP-S70016K is a heavy-duty shaft mount roller rocker arm kit engineered for extreme applications with high spring pressure and lift geometry. Designed for Big Block Mopar 350-440 engines from 1959-1978, this kit features full roller rocker arms with a 1.6 ratio and an orange anodized aluminum finish for increased durability. Each kit includes rocker arms, shafts, spacers, hold down clamps, adjusters, and nuts. The rocker arms utilize needle bearings that allow for enhanced oil flow to the rockers. These units are designed to work with stock valve covers up to .900 lift, but require the removal of oil baffles. It is noted that oil restrictors may be necessary to maintain adequate oil pressure. The specs for this kit include a 0.875-inch shaft diameter and a maximum spring diameter of 1.650 inches. They are not self-aligning and require the use of ball/cup style pushrods; their length will need to be determined after installation of the rockers.
