GM LS Engine 03/Earlier ARP2000 Head Stud Kit, 12 pt

All Pro Series ARP2000 head studs are centerless ground, heat treated prior to thread rolling and machining, nominally rated at 220,000 psi tensile strength and are reusable as compared to the OEM Torque to Yield (TTY) head bolts. Optimum design, enhanced reliability and increased strength are the main attributes of ARP's Pro Series head stud kits.

  • Ten M8 studs
  • Thirty parallel ground washers
  • Thirty 8740 chrome moly 12 point nuts

GM LS Engine Main Stud Kit

ARP Main Stud kits eliminate main cap walk and fretting, as well as protect the threads in your engine block. All kits come complete with high quality nuts. The studs are manufactured from 8740 Chromoly steel, heat-treated in-house to 190,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others.

  • Ten Inner studs - 4.770 long
  • Ten outer studs - 4.550 long
  • Ten side bolts - M8 bolts
  • Twenty  8740 chorme moly 12 point nuts
