Revhigh LS7 Rocker Arm Upgrade Trunion Kit

 

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.
 
Kit is for LS7 engines only.  See Part Number 55100 for other LS applications


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 (shorter for LS7's)
  • 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.
