Rocker Arm Bolt LS7 M8 x 1.25 x 35MM UHL

The Rocker Arm Bolt LS7 M8 x 1.25 x 35MM UHL is a precision fastener designed for high-performance GM LS-series engine builds, especially those utilizing LS7 cylinder heads. This bolt is essential for anyone involved in rebuilding or servicing LS powerplants, whether for street performance, track vehicles, or restorations.

Manufactured from hardened steel and featuring a black oxide finish, this bolt is engineered to meet OEM specifications for diameter, pitch, length, and head geometry. The M8 x 1.25 metric thread is precisely cut to factory tolerances, ensuring consistent clamping force when torqued to specification, which is crucial for maintaining the integrity of the valve train under high-stress conditions.

Engine builders and technicians restoring LS-series platforms will find this bolt particularly beneficial, as it allows for the replacement of individual fasteners without the need to replace entire assemblies. Correct fastening hardware is vital for ensuring rocker arm geometry and preload remain within factory parameters, as using undersized or incorrect fasteners can lead to performance issues.
