ARP Pro Series Head Bolt Set, Hex
Fits GM LS Series with All Same Length Bolts (2004-On)

PROFESSIONAL SERIES

All Pro Series bolts are cold-forged to ensure molecular integrity, heat-treated prior to thread rolling and machining, and are rated nominally at 200,000 psi. ARP Pro Series head bolt kits are application specific & designed for use with typically competition only components. These fasteners deliver superior strength and meet the ARP €œZERO defect€“ ZERO failure quality standard. Hardened and parallel-ground washers are included with each kit to ensure even load distribution and accurate torque readings. All Pro Series head bolts have a reduced wrenching hex or 12-point head and wide area flange to eliminate the need for valve train removal for cylinder head re-torquing and permits the use of larger diameter valve springs. Most applications have undercut short bolts that can help eliminate head gasket failures through providing more €œstretch to compensate for the additional compression of gaskets.
