Aluminum Roller Rocker Arms
These are one of the strongest, most ratio-accurate light weight rocker arms available. You can expect 15+ horsepower just by bolting these on and tossing those heat generating stamped OE pieces, plus you'll increase your rpm range thanks to our lightweight construction. Extruded from 2024 aluminum, these rocker arms feature the best of everything! Including US-made bearings in the fulcrum, 4130 trunion, roller axle and adjusting nut, heat-treated 8620 steel roller tip and pushrod seat. Clearanced for 1.625" spring and retainer combinations. We finish them off with a stealth black anodized finish
