Manley 434212-1 Ratio: 1.65 - Stud: 7/16 in. - Fits: 1958-1981 Pontiac V8 (287-455 and 4.3L)
Our all-new Pro Series Billet Aluminum Rocker Arms are engineered for top performance across street, strip, and track applications. Machined from high-quality 2024 billet aluminum extrusions, these rockers feature precision-ground needle and cage bearings, reducing friction with full complement needle bearings. With the heat-treated and polished steel nose rollers, axles, and trunions, wear is minimized for lasting durability. An anodized finish enhances protection, and each 16-piece set comes complete with Poly Locks for secure installation.
