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.
OEM bolt's can be reused with this trunnion kit or choose to upgrade your bolts to one of the following:
Michigan Motorsports Allen Head Bolts
Brian Tooley 12pt heads
ARP 234-7207 Rocker Arm Stud Kit

BTR Rocker trunnion upgrade
Easy install, simpler and seemingly stronger design than factory, went together good on my L96 and will hopefully pair well with the truck norris cam and vvt delete kit that i am installing as well.
