Bolt - Rocker Arm 7.0L LS

The Bolt - Rocker Arm 7.0L LS from Chevrolet Performance (MPN 11588791) is an OEM-specification replacement fastener engineered for GM LS-series cylinder heads. This is a critical drivetrain component—not a tactical item, but rather a precision engine hardware piece that demands exact fitment and material integrity. The rocker arm bolt secures the rocker arm assembly to the cylinder head, where it experiences thousands of load cycles under varying engine temperatures and pressures.

This fastener measures 8mm x 1.00 thread with a 1.875-inch length and is manufactured from steel with a black oxide finish for corrosion resistance. Black oxide coating provides a durable protective layer that resists surface rust and minor oxidation—critical for engine bay environments exposed to moisture and thermal cycling. The 0.04-pound weight reflects the precision machining typical of OEM Chevrolet Performance components. LS-series engines demand exact hardware specifications; substituting incorrect fasteners risks rocker arm misalignment, valve train noise, and potential catastrophic engine damage.

Buyers restoring, rebuilding, or servicing LS-platform engines—whether in light-duty trucks, muscle cars, or performance builds—rely on OEM-matched hardware to maintain factory engineering tolerances. Chevrolet Performance supplies this bolt as a single-unit replacement, suitable for technicians who need to replace damaged, stripped, or corroded fasteners during cylinder head work. This part integrates seamlessly with 7.0L LS applications and other compatible LS variants where head bolt specifications match this standard.

LS-series engines remain industry standard for both original equipment and performance aftermarket builds. Sourcing correct OEM fasteners ensures repeatability and eliminates guesswork during assembly—a principle any serious engine builder or restoration technician understands. This Chevrolet Performance bolt delivers authentic spec compliance at competitive pricing.
