    Product Description

    LS1 Rocker Arms with Trunion Bearings Professionally Installed

      LS1 Rocker Arms have been disassembled and new Trunion Bearings have been professionally installed

    LS1 style bolts are included 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 LS rocker arms and install new LS1 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 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.

    Fits all these applications: LS1/LS2/LS6/ LR4 Vortec 5300 LM7 L59 LM4 L33 – 4.8/5.3/5.7/6.0/ Engines. Will not fit Rectangle Port/"LS3" Style heads. 

    This kit includes:
    16 LS Series Rocker Arms with Roller Bearing Trunnion Upgrade Installed
    16 High Strength Allen head bolts for LS Rockers
