ARP - Head Stud Kit - 1994-2002 Ford 7.3L Powerstroke 250-4201
Part # 250-5801
Main studs hold down the main caps on the crankshaft.
Studs provide the ability to obtain much more accurate torque values because the studs don't twist during tightening as do bolts. Because the studs remain stationary during nut tightening, the studs stretch in one axis alone, providing much more even and accurate clamping forces.
