Product Description:
Hawks Motorsports is pleased to offer our clients the following 234-3726 LSA 6.2L 12-Point Pro Series Cylinder Head Bolt Kit, ARP. This head bolt kit is specifically intended for the GM LSA supercharged 6.2L engine and features ARP Pro Series 12-point cylinder head bolts manufactured for high-strength engine applications. The kit includes hardened parallel washers designed to provide even load distribution and consistent torque readings. ARP identifies the 234-3726 as a Chevrolet LSA application.
When you're putting an LSA together, the cylinder head fasteners aren't the place to cut corners. A supercharged 6.2L making serious power puts plenty of pressure on the head gasket and fasteners, and upgrading the clamping hardware is part of building an engine you can lean on. The 12-point heads also give you solid tool access when you're working around the tight confines of an LS-based engine bay.
The 234-3726 is an ARP Pro Series head bolt kit using ARP2000 material. Current ARP catalog information identifies 234-3726 in the Gen IV 6.2L LS9/LS-series head-bolt application listing, while ARP's individual product page identifies the application as Chevrolet LS-series LSA. Hawks Motorsports specifically lists this kit for the GM LSA supercharged 6.2L engine.
