Description

                                   
  •  Kit includes: 16 Gen III LS Series Rocker Arm bodies - 32 rocker arm bearings, 32 rocker arm retaining rings, 16 rocker arm trunnions 
  •  AMS Racing LS Series retrofit trunnions are designed to convert stock LS Series rocker arms into captured roller trunnions for added durability in higher horsepower applications. 
  •  We utilize LS rocker arms and install new LS1 rocker arm retrofit trunion kit that replaces the cageless, loose OEM needle bearings and powdered metal trunion with a premium 8620 steel alloy trunion and caged roller bearings for added durability. The caged roller bearings that greatly reduce the possibility of the bearing failure experienced with stock LS1 needle bearings, which can send loose needles throughout the engine upon failure. 
  •  For use with a max .600" lift camshaft in all these applications: LS1 LS2 LS6 LR4 Vortec 5300 LM7 L59 LM4 L33 – 4.8 5.3 5.7 6.0 Engines
