Get Reliable Performance with PRW’s Pro Series Billet Aluminum Rocker Arms

Whether it’s for the street, strip, or track, PRW’s Pro Series Billet Aluminum Rocker Arms offer the reliable performance you need. It’s why professional racers, engine builders, and hot rod enthusiasts across the world trust the brand.

Made with high-strength 2024 or 6061 T-6 aluminum extrusions, the rockers are precision CNC-machined and hand-finished to ensure quality. They let you use larger valve springs and retainers to handle higher-lift camshafts. The full-cage, friction-reducing needle bearings add durability, and the roller tips are made from heat-treated GCR15/52100 or CR40 steel and hardened to minimize friction and wear that occurs between the tip and the valve stem.

Other features include:
• Wide range of ratios to suit almost any cam profile
• Rated at 750 lbs. open spring pressure (Super-Duty models rated at 800 lbs. open spring pressure)
• Internal oiling system for long-lasting performance
• Shot-peened to increase strength and reduce stress risers
• PRW RockerLocs included
• Distinctive blue or black anodized finish

PRW Pro Series Billet Aluminum Rocker Arms come in sets of 16 for most popular American V8 engines.
