The bushing design provides superior lubrication to the trunnion while also providing maximum load capability. Our innovative design prevents premature failures caused by the weak O.E. or replacement needle bearings, eliminating the possibility of debris from a bearing failure that can cause severe engine damage. Our special C932 bushing material is bathed in oil via grooves at 2 different locations on the trunnion..
These channels constantly feed oil to the bushing surface ensuring proper lubrication. The greater surface of our bushed trunnion will support 300 times more load than a needle bearing trunnion. Our bushing gets more lubrication and has less load applied to it than the bushing in the small end of a connecting rod, giving it long service life. Includes two stands - enough for both heads.

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. 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.

High port flow gives great performance now, and more later when additional upgrades are done.
Heads are fully assembled with springs and valves, and are available in silver or black powder-coat finish to match OEM components.
Compression ratios vary depending on cylinder heads chosen, pistons used and engine displacement.
Heads are machined for compression releases (sold separately).
S&S rocker boxes required when using S&S compression releases.
