COLORADOSPEED LS Rocker Arm Trunnion & Bushing Upgrade Kit [10 GROUP PURCHASE]

DISREGARD THIS OLD IMAGE. THE LATEST VERSION IS A 3RD REVISION WHICH WE SELL

We use micro-polished hardened steel shafts and C932 bearing bronze bushings for our LS rocker arm trunnion & bushing upgrade kits. C932 bearing bronze is consistently used for bushings, thrust washers, bearings and pump/valve components due to its high strength, wear and corrosion resistance. By utilizing bushings instead of needle bearings, there are no small parts that may come loose and damage an engine. The bronze bushing also provides a larger surface area for distributing the load and the oil channels improve lubrication at the rocker arm.

Each trunnion is micro-finished to a specific RMA finish. The bushings are centerless ground and then micro-polished to clearance specs. Oil from the rocker is fed directly to the non-loading axle area of the trunnion and does not interfere with load capacity. The proprietary bushing material is fed with an oil channel at the 12 o'clock positions of the trunnion. This channel constantly feeds oil to the bushing surface ensuring proper lubrication unlike needle bearing trunnions that have to rely on oil finding it's way to the needles. The greater surface area of the bushing will support 300 times the load of what a needle will due to the fact on a needle bearing upgrade, your load is dependent on 3 or 4 needles to carry the load. The needle with the largest diameter will carry most of the load. Also there is no chance of needle bearings destroying the engine when using much more aggressive cam profiles and a rocker arm fails.

100% engineered and made in the USA.

Each kit includes 16 trunnions, 32 bushings and 32 c-clips and can be used with the stock rocker bolts. Fits all OEM LS rockers (LS1, LS6, LS2, LS7 and LS3).
