    Product Description

    Brian Tooley Racing LS Rocker Arm Upgrade Trunnion Kit

    The Brian Tooley Racing (BTR) LS Rocker Arm Upgrade Trunnion Kit is designed to convert your stock LS rocker arms into captured roller bearing rockers, providing a reliable and durable solution for high-performance applications. The stock factory bearings are a known failure point in LS engines, often sending loose needle bearings throughout the engine when they fail. This upgrade eliminates that risk while improving rocker arm stability and performance.

    Strong, lightweight factory LS rocker arms become as reliable as premium roller rockers once upgraded with these trunnions. A must-have for any LS build, whether you’re running a stock 4.8L or a 1,000+ hp turbocharged setup.

    Key Features:

    • Captured Roller Bearing Design: Prevents needle bearings from escaping into the engine, ensuring long-term reliability.
    • Improved High-RPM Stability: Provides smoother operation and stability for aftermarket camshaft, turbo, supercharger, or nitrous builds.
    • Cost-Effective Upgrade: Retains lightweight OEM rocker arms while matching the durability of expensive roller rockers.
    • Proven Performance: Used successfully in builds from stock engines to 1,000+ hp turbo combinations.
    • Flexible Bolt Options: OEM bolts can be reused, or upgrade to Michigan Motorsports Allen Head Bolts, Brian Tooley 12pt bolts, or ARP 234-7207 stud kit.

    Applications:

    Fits all Gen 3 & Gen 4 LS engines, including: LS1, LS2, LS3, LS6, L99, LS4, LQ4, LQ9, L76, L92, LR4, LM7, L59, LM4, L33, L98, L77, LY6, LFA, LZ1, LY2, L20, LMF, LH6, LY5, LMG, LC9, LH8, 4.8L, 5.3L, 5.7L, 6.0L, 6.2L.

      BTR Rocker trunnion upgrade

      Posted by Michael. P on Jan 18th 2024

      Easy install, simpler and seemingly stronger design than factory, went together good on my L96 and will hopefully pair well with the truck norris cam and vvt delete kit that i am installing as well.
