GM LS S/S Intake Bolt Kit 12pt

The GM LS S/S Intake Bolt Kit 12pt is a precision fastener assembly designed for General Motors LS-series engine platforms, widely trusted in performance and restoration applications across automotive, off-road, and powersports builds. This stainless steel intake manifold bolt kit addresses a critical need in engine assembly: replacing factory fasteners with corrosion-resistant hardware that maintains clamp load integrity under thermal cycling and extended service. Built by ARP (Applied Racing Products), a leader in high-strength fastener engineering, this kit ensures reliable sealing and durability where factory hardware often fails.

The kit features 12-point head bolts in polished stainless steel construction, offering superior corrosion resistance compared to zinc-plated OEM fasteners while delivering the aesthetic appeal demanded by modern engine builds. The 12-point head geometry provides superior tool contact and reduces the risk of fastener rounding during installation—critical when working with precision-machined aluminum intake manifolds. Stainless steel material maintains consistent tensile strength across temperature ranges, preventing stress relaxation that compromises manifold gasket sealing; polished finish resists oxidation and simplifies visual inspection for proper torque application and bolt condition during maintenance intervals.

This intake manifold bolt kit is essential for LS engine rebuilds, stroker conversions, and high-mileage restorations where original fasteners have corroded or fatigued. Technicians and engine builders benefit from ARP's precision tolerancing, which ensures proper fit in GM LS manifold mounting bosses without modification. Installation requires standard hex key tooling; proper torque specs should follow engine manufacturer guidelines or ARP documentation to achieve optimal gasket compression and long-term reliability. Compatible with all GM LS variants including LS1, LS2, LS3, LS6, LS7, and LS9 platforms used in Camaros, Corvettes, Silverados, and engine swap applications.
