Product Description
ARP 134-3609 High Performance Cylinder Head Bolt Kit 1997-2003 4.8 5.3 5.7 6.0 Gen 3
Please verify which head bolts you need as GM used two different style LS head bolts:
1997-2003 Blocks used QTY 8 155mm Bolts, QTY 2 100mm bolts, and QTY 5 45mm bolts
2004-2014 Blocks used QTY 10 100mm bolts, and QTY 5 45mm bolts
ARP HP bolts are cold forged to ensure molecular integrity, heat treated prior to thread rolling and machining, are rated nominally at 190,000 psi. ARP HP head bolt kits are application specific. Hardened and parallel-ground washers are included with each kit to ensure even load distribution and accurate torque readings. These HP head bolts have a reduced wrenching hex and a wide area flange that help eliminate the need for valvetrain removal when re-torquing cylinder heads.
