About this part

Product Details

ARP makes this CA625+ 12-point head stud kit for high-performance GM LS engines. If you're building a serious engine for your 1997-2004 Corvette, or a 1998-2002 Camaro or Firebird, these studs offer a solid upgrade over stock head bolts. They provide more consistent clamping force, which is crucial when you're pushing the limits with boosted or high-compression setups.

This kit uses ARP's CA625+ material, a proprietary alloy that offers superior tensile strength and fatigue resistance compared to standard ARP 8740 material. The 12-point nuts and parallel ground washers ensure even load distribution. Each stud is centerless ground for a perfect concentricity and heat-treated to achieve optimal strength.
