Ever had your factory knuckle studs loosened, rust, or even shear right off the knuckle? ARP (Automotive Race Products), the world leader in fastener technology, has become an industry standard when it comes to the highest strength and greatest quality fasteners.
These studs are made from a superior ARP2000 material - an exclusive, hybrid-alloy developed to deliver superior strength and better fatigue properties. The ARP2000 material is capable of achieving clamp loads in the 215,000-220,000 psi range.
Studs are .250 (1/4 inch) longer than stock to accommodate all aftermarket steering arms. Each stud features an 8mm hex head for easy removal with common tools.
Studs should be tightened to 20-25 ft-lbs in the knuckles. Stud nuts should be tightened to 80 - 100 ft-lbs. Both kits include free .2ml Turbo-Lock Red Permanent Threadlocker.
