PRW GM LS Pro Series Rocker Arms bring extra strength to your valvetrain without modification. PRW set out to create a stronger rocker arm that could drop in easily for a quick and efficient upgrade. Each arm is made using quality steel that's been reinforced in critical areas to provide more rigidity; and they're polished to eliminate stress risers and prevent cracks.

Choose between a bearing trunnion or bushing to complement your combination and complete your valvetrain. It doesn't matter if you're making big power in your muscle car, or just want the reliability for long hauls in your truck—PRW BTP rocker arms have you covered. Order the set recommended for your year, make, and engine application.
