    Product Description

    LS3 Rocker Arms - With Roller Trunnion Kit Installed

    Fits 6.0L 6.2L L99 L76 L92 L96 LS9 LSA LY6 L77

    These LS3 Intake Rocker Arms feature offset fulcrum for use on LS3 L99 L76 L92 LS9 LSA "square port" or "rectangle port" cylinder heads. Include new LS3 specific bolts for installation.

    Whether you have a stock LS motor or a highly modified LS motor, replacing your rockers with a true roller bearing setup is highly recommended. The stock bearings have a tenancy to fail. These rocker arms are a must have for any aggressive heads and cam combo. We utilize LS3 rocker arms and new LS rocker arm retro-fit 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 new design from utilizes caged roller bearings that greatly reduce the possibility of the bearing failure experienced with stock LS needle bearings, which can send loose needles throughout the engine upon failure.

    This kit includes:
    16 New LS3 Series Rocker Arms with Upgraded Roller Bearing Trunnion Kit Installed
    16 Bolts for LS3 Style Rocker Arms
