    Product Description

    LS1 Rocker Arms Bushing Trunnion 4.8 5.3 5.7 6.0 6.2 LSX LQ9 LS2 LS3    
    Includes: 16 Trunions, 32 Bushings, 32 Circlips, 16 LS Bolts and 2 Installation Washers

    • Fits all OEM LS Rocker Arms.
    • Replacement Trunnion Kit for LS Engines 
    • Micro-polished hardened shafts with C932 bearing bronze bushings 
    • No small parts to come loose and damage your engine! 
    • Less prone to failure and loads are spread over a wider area 
    • Oil channels keep the rocker arm lubricated

    LS CHEVROLET BUSHING TRUNNION KITS: 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.

      Seems good quality. Everything fit very well in the rockers and even came with extra snap rings cause you know they like to go flying every once in a while!

      These seem to be a great value offering, and much nicer than the needle bearing offerings. Installation was pretty easy, I haven't gotten a chance to run the car with them yet.

      LS1 rocker arm bronze bushings

      Posted by Ben F on Feb 19th 2019

      Very quality kit, pressed in extremely well - no imperfections found. Can't wait to see how they hold up! Used the Comp Cams upgraded needle bearing kit, I like this much better. Will by again for the next engine I build for sure.
