  • Brian Tooley LS Rocker Arm Upgrade Trunnion Kit includes 16 upgraded bolts - stock bolts can be used.
  • 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
  • Used on all LS style rocker arms including the following: LS1 LS2 LS3 LS6 L99, LS4, LS9 LSA LQ4 LQ9 L76 L92 LR4 LM7 L59 LM4 L33 L98 L77 LY6 LFA LZ1 LY2 L20 LMF LH6 LY5 LMG LC9 LH8 LS4 4.8 5.3 5.7 6.0 6.2
