Product Description:
Hawks Motorsports is pleased to offer our clients the following LS1/LS6/LS2/LS3/LS7 12-Point Front Timing Cover Bolts, ARP, part number 134-1502. This ARP timing cover bolt kit is designed for GM Gen III/IV LS-series engines and features black oxide-finished 8740 chrome moly bolts with compact 12-point heads. ARP identifies the 134-1502 specifically as the Gen III/IV LS Series 12-point timing cover bolt kit.
For the gearhead building an LS from the block up, the little details matter. Once the timing cover is going on, this is the kind of hardware that gives the front of the engine that finished, purpose-built look instead of leaving a pile of mismatched factory fasteners scattered across a fresh build. The compact 12-point heads are especially handy around the front of an LS where access can get tight, making this a solid choice for a street car, swap, or serious engine build where the hardware deserves as much attention as the parts underneath it.
The 134-1502 uses 8740 chrome moly steel with a black oxide finish and a 12-point head design. ARP rates its timing-cover fasteners at approximately 170,000 psi tensile strength, and ARP's catalog indicates that washers are included with its timing-cover bolt kits.
