430-2001 LS1/LS6/LS2 Stainless Steel Hex Head Intake Manifold Bolts, ARP

Hawks Motorsports is pleased to offer our clients the following 430-2001 LS1/LS6/LS2 Stainless Steel Hex Head Intake Manifold Bolts from ARP. This polished stainless steel intake manifold bolt kit is designed for GM LS-series engines using the factory-style intake manifold configuration. The kit features six-point hex heads, M6 x 1.0 threads, and a set of 10 bolts with companion washers. ARP's current application information specifically identifies the 430-2001 for LS1, LS4, LS6, 4.8L-RL4, 5.3L-LM7 and 6.0L-LQ4 applications.

For the LS builder who likes an engine bay that looks as good as it runs, these polished stainless ARP bolts are a great finishing touch. The six-point hex head keeps the look clean and purposeful, while the polished stainless finish adds some serious hardware bling without going over the top. Whether you're freshening up an LS1 F-body, detailing a Corvette engine bay, or putting the finishing touches on an LS swap, replacing the factory intake fasteners with quality ARP hardware is a simple upgrade that makes the whole top end look more serious.

The 430-2001 uses a wide underhead flange and companion washers to help distribute clamping load across the intake manifold mounting points. ARP also specifies precision-rolled threads designed to promote consistent torque loading and reduce galling. The fasteners are nominally rated at 180,000 psi tensile strength.
