S/S Header Bolt Kit - 6pt. GM LS

The S/S Header Bolt Kit - 6pt. GM LS by ARP is a crucial upgrade for any serious LS engine builder or performance enthusiast engaged in a modern small-block swap. This kit is designed to withstand the extreme thermal cycling and combustion pressures that standard fasteners cannot endure, ensuring a reliable connection for your exhaust manifold or header.

Constructed from high-quality stainless steel, this kit offers superior corrosion resistance and thermal degradation compared to mild steel alternatives. The 6-point head design helps distribute force evenly across the fastener, reducing stress concentration and minimizing the risk of fatigue failure, which is particularly important in high-revving applications or aggressive builds.

Engine builders and mechanics working on LS conversions, turbo builds, or stock engine rebuilds recognize ARP header bolts as the industry standard for durability and fitment. This kit is compatible with both traditional cast-iron manifolds and aftermarket long-tube headers, providing the reliability needed for long-term service.
