PQx ® Platinum SERIES Alloy Steel UpGrade Rocker Arms for GM LS3/L92/LS9
The exclusive PQx ® Gen III/IV Bolt-to-Pedestal BTP design Rocker Arms by PRW, are the perfect alternatives to increase the durability and performance of your GM LS Series valve train. These upgrade drop-in replacements fit under stock valve covers and designed specifically for high RPM conditions. PRW factory engineering and technicians enhanced the design structure of proven stock rocker arms with heavy-duty rails and modifications to the nose to reduce drag. We added billet steel trunnions, full complement roller bearings, and hardened steel retaining rings to complete the assembly.
The upgraded rocker arms include alloy steel Grade 12.9 M8 fasteners specifically designed to minimize interference when used in conjunction with higher lift camshafts. These combined components improve the reliability of your GM Gen III/IV engine and are a must whenever incorporating high performance camshaft or higher load valve springs.
