PRW Rockers are designed to maximize the valvetrain efficiency of your Oldsmobile Engine
PRW Platinum Series Stainless Steel Rocker Arms are made from high strength 17-4ph stainless steel with each piece precision CNC machined and finished by hand to ensure that the customers receive the very best PRW has to offer. PRW stud mount steel rockers are specially machined to allow for larger springs and retainers with full-cage friction reducing needle bearings for added durability. These full roller designs feature large micro-polished trunions for superior strength. The nose rollers and shafts are Cr40 steel, heat-treated and hardened to minimize the wear that naturally occurs between the roller tip and the valve stem.
As with other PRW products, these are in-stock for immediate delivery. All PRW aluminum rockers come complete with PRW Extreme Pressure Assembly Lube and RockerLocs™ at no additional cost.

*Picture may not be of actual ratio assembly, however pic does display quality of rocker. Rocker arms are nearly identical in quality and appearance and compete directly with the overpriced sets.
Others claim to have equally good products but close scrutiny by professional engine builders and machinists tell a different story. Beware of false claims.
Imitation sets of rocker arms are being sold all over ebay. Notice in the picture of a PRW Stainless Steel Rocker arm the clipped ends of the roller pin. Unlike all PRW rocker arms, the cheap $100 rocker arms have pressed in pins which are prone to stress cracks that will ultimately result in failure. Those designs definitely cannot stand up to high spring pressures and high RPM like PRW rocker arms.
