Lightweight Performance for Small Block Mopar

The PRW Platinum Series Shaft Mount Rocker Arm System is engineered for the serious Small Block Mopar builder. Featuring a full roller design and lightweight aluminum construction, these rockers are designed to reduce valvetrain mass while providing maximum stiffness. The 1.5 ratio is perfect for street-performance and race engines, offering reliable valve actuation at high RPMs.

Why Choose Platinum Series?

  • Full Roller Design: Reduces friction at both the tip and the trunnion for smoother operation.
  • Clear Anodized Aluminum: High-strength, lightweight material that dissipates heat effectively.
  • Shaft Mount Architecture: Eliminates the need for guide plates and provides superior rocker alignment.
  • Precision Engineering: Designed for a perfect fit on Small Block Mopar cylinder heads.

These rockers are the gold standard for those looking to improve throttle response and engine longevity. By reducing reciprocating mass in the valvetrain, your engine can rev faster and more reliably. The clear anodized finish not only looks great but also provides a protective layer against corrosion.
