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.
