The Brian Tooley Racing (BTR) LS Rocker Bolts are designed specifically for trunnion upgrade kits on LS1, LS2, and LS3 engines. These bolts are shorter than factory bolts, ensuring proper fitment and secure installation when upgrading the rocker arm trunnions. Using factory-length bolts with an upgraded trunnion kit can cause improper seating, leading to potential valve train failure. With these performance-engineered bolts, you get enhanced durability, precise fitment, and reliable valve train stability for high-performance applications.
