Brian Tooley LS1 Rocker Arm Trunion & Bolt Kit 4.8 5.3 5.7 6.0 6.2 Trunnion BTR
  • Brian Tooley LS Rocker Arm Upgrade Trunion Kit Includes Allen Head Bolts
  • 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.

  • 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).
