Precision-forged from heat-treated alloy steel or lightweight roller-tip aluminum, these rocker arms translate camshaft lobe lift straight to your engine valves with minimal mechanical friction. Featuring hardened trunnion bearings, micro-polished roller tips, and high-pressure oil passages, they withstand intense RPM thermal stress without valve float or pushrod wear. Every exact-fit rocker arm kit includes model-specific rocker shafts, fulcrum balls, and adjusting nuts for a direct bolt-on cylinder head overhaul. Reclaim smooth engine valve timing, reduced valvetrain noise, and uncompromising acceleration.
