Rocker Arm Bolt (1) LS1/LS2/LS3/LS6

The Rocker Arm Bolt (1) LS1/LS2/LS3/LS6 from Brian Tooley Racing is an essential fastener for any serious LS engine builder or performance enthusiast undertaking valvetrain work. This individual bolt is engineered to secure the rocker arm assembly on GM's legendary LS platform, where cylinder head integrity and valvetrain geometry directly impact power output, rev capability, and engine longevity. Whether you're rebuilding a stock engine, upgrading to a performance cam, or assembling a complete race motor, having quality OEM-spec or upgraded fasteners is non-negotiable.

Brian Tooley Racing fasteners meet or exceed OEM specifications and are manufactured to tight tolerances that ensure consistent clamping force and load distribution across the rocker arm saddle. The bolt's precise thread geometry and head design prevent loosening under thermal cycling and high-RPM operation—conditions where inferior fasteners can fail catastrophically. LS engines routinely see elevated valve spring pressures and aggressive cam profiles; this bolt is designed to withstand those demands without galling, stripping, or yielding under load.

Mechanics and engine builders rely on Brian Tooley Racing fasteners for LS1, LS2, LS3, and LS6 applications—from street builds to dedicated track engines. This single bolt is ideal as a replacement for stripped or damaged fasteners during disassembly, or as part of a complete valvetrain refresh using upgraded components. Proper torque specification and threadlocker application ensure reliable performance; always follow manufacturer guidelines and use a calibrated torque wrench during installation to maintain valve timing and prevent leaks.
