    Upgrade your factory LS or LT rocker arms with this premium bushing trunnion kit, designed to eliminate the weaknesses of OEM needle bearings. Featuring micro-polished hardened shafts paired with C932 bearing bronze bushings, this kit offers increased durability, better lubrication, and superior load capacity. With no small needle bearings to fail, you can rest assured your engine is protected from catastrophic debris-related damage.

    Key Features

    • Fits all OEM LS rocker arms
    • Replacement trunnion kit for LS and LT engines
    • Micro-polished hardened shafts with premium C932 bronze bushings
    • No small needle bearings to break loose and damage the engine
    • Improved load distribution for increased reliability
    • Integrated oil channels keep rocker arms consistently lubricated

    Why Choose a Bushing Trunnion Kit?

    The innovative bushing design provides maximum lubrication and load-handling capability, far surpassing OEM or replacement needle bearings. Oil grooves at two locations feed constant lubrication to the bushing surfaces, ensuring long service life. The greater surface area of the bushed trunnion supports over 300 times more load than a needle bearing, making it less prone to failure. With better lubrication and reduced load stress, this kit delivers long-term performance and peace of mind.
