Hawks Motorsports is pleased to offer our clients the following 130-2001 LS1/LS6/LS2 Chromoly Hex Head Intake Manifold Bolts, Set of 10, ARP. This ARP intake manifold bolt kit is designed for Chevrolet LS-series applications using the factory-style OEM intake manifold configuration. The kit includes 10 black oxide chromoly bolts with hex heads and companion washers. ARP specifies an M6 x 1.0 thread and 4.480-inch underhead length for this application.

For the gearhead putting together an LS-powered street car, swap, or performance build, the little details matter. Once that intake is sitting on top of the engine, you want solid, properly sized hardware holding it down—not a collection of mismatched bolts pulled from the parts bin. These ARP fasteners give the engine bay a clean, purpose-built look while providing the kind of precision-machined hardware you'd expect when you're taking the time to build an LS the right way.

The 130-2001 kit uses black oxide 8740 chromoly construction, a hex head design, and a wide underhead flange with companion washers intended to distribute clamping load across the intake manifold mounting points. ARP's application information identifies this part for LS1, LS4, LS6, 4.8L RL4, 5.3L LM7 and 6.0L LQ4 applications using the stock/OEM-style intake configuration.

This kit is specifically associated with the stock intake manifold application. ARP lists separate fastener kits for LS applications using Edelbrock intakes with 45mm underhead length requirements and GM Performance intakes with 55mm requirements, so intake configuration should be verified before ordering.
