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-torqueing cylinder heads.
