Description
ARP | Cummins 12 Valve 12MM Headstud Kit (89-98)
ARP Pro Series cylinder head studs are cold-forged to ensure molecular integrity. They are heat-treated prior to thread rolling and machining, and all kits come complete with hardened parallel washers for an even load distribution and accurate torque readings.
It is for good reason that virtually every top professional engine builder relies on ARP Pro Series head studs for their all-out competition powerplants. Simply stated, theres not a better stud setup on the market today. ARP uses a premium grade 8740 alloy that is rated far superior to aircraft quality. Then, each stud is placed vertically in special racks and precisely heat-treated to 220,000 psi. ARP studs are thread rolled after heat-treat, which gives them about 1000% (thats ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). You wont find a better quality stud on the market from any other source.
Features:
- Increased Strength
- Increased Reliability
- ARP2000 rating
- 220,000 PSI Tensile Strength
- 8740 Chrome moly construction
ROCKER PEDESTALS WILL NEED TO BE MACHINED FOR HEAD STUD INSTALL
