    Product Description

    Michigan Motorsports Rocker Arm Trunion Kit - Specific to Gen V LT1 LT4 LV3 L83 L86

     These LS Series retrofit trunion kits are designed to convert stock LS Series rocker arms into captured roller bearing rocker arms.   The factory bearings are a known failure on the LS Engines.  When they fail they send small bearings through the entire engine.  The upgraded trunions use a captured roller bearing allowing for a reliable smooth rotation. The upgraded trunions also give more stability at higher RPM. 

    We use these trunion kits in anything from stock 4.8's all they way up to 1,000+hp turbo motors. 

      The stock factory LS rocker arms are very strong and very light. Once you upgrade the bearings and trunions the rocker arms handle similar to very expensive roller rocker arms (at a fraction of the cost). These are a must have for anyone installing a aftermarket Cam, Supercharger, Turbo or Nitrous. The Kit includes the rocker arm trunions, rocker arm bearings, and rocker arm retaining rings and upgraded bolts for a complete installation. The bolts we supply are slightly shorter than factory bolts so they do not protrude into the intake ports. Bolts are stronger than a grade 8 bolt with a minimum tensile strength of 170,000 psi.

    16 rocker arm trunions

    32 rocker arm bearings
    32 rocker arm retaining rings
    16 upgraded bolts 
    2 washers for pressing bearings  

    Installation is fairly simple with the use of a press or a simple vise along with basic hand tools.  Instructions are included to aid in the installation.
