Brian Tooley BTR Trunnion Kit V2 Rocker Arm Trunion LS1 LS3 4.8 5.3 5.7 6.0 6.2
- BTR Trunnion Kit V2 Rocker Arm Trunion Kit. The all new Trunnion Kit V2 features a Trunnion with pre-installed inner race bearings..
- The V1 kits have stood up to an enormous amount of abuse, but BTR decided to upgrade the to a pressed inner race comprised of 52100 Heat Treated Bearing Steel, over the more commonly used 8620 Carburized Steel found in our V1 kits and many OEM applications..
- 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)..
- Additionally, these feature a self oiling axle with priority feeding to the Trunnion itself..
