Rocker Arm Bolts (16) LS1/LS2/LS3/LS6

The Rocker Arm Bolts (16) LS1/LS2/LS3/LS6 from Brian Tooley Racing are engineered fasteners designed specifically for the GM LS engine family—the platform of choice for high-performance builds, street rods, and forced-induction applications. These bolts secure the rocker arms to the cylinder head, a critical duty that demands precise specifications and reliable clamping force under extreme valve train acceleration and combustion pressures. Whether you're rebuilding a stock LS engine or upgrading a modified platform, quality rocker arm bolts are non-negotiable for proper valve train geometry and longevity.

Each bolt in this set of 16 features an 8mm x 1.25 thread pitch and measures 2.5 inches in length, meeting OEM LS specifications for rocker arm retention. Constructed from hardened steel and finished in black oxide, these bolts resist corrosion while providing the surface durability needed in high-heat engine bays. The black oxide coating also prevents galling during installation and removal—a common issue with raw fasteners in aluminum head applications. Proper torque sequence and specifications are critical; these bolts must be tightened to manufacturer specifications to maintain consistent preload across all 16 rocker arms.

LS engine builders and mechanics rely on dedicated rocker arm bolts when reassembling any LS1, LS2, LS3, or LS6 head—whether during routine maintenance, cam swaps, or complete engine rebuilds. Installation requires proper torque specifications and a sequential tightening pattern to ensure even clamping load and prevent rocker arm misalignment. This 16-piece set supplies all necessary bolts for a complete engine, eliminating the need to source fasteners individually and ensuring uniform quality across your valve train assembly.
