ARP 2342503 Stud Kit

Awesome product! Just perfect.

High quality and can be reused. Worked on a GM 6.0

what i was looking for

Factory bolts are one shot use. Step up to the best.

dont reuse the old bolt and go with arp every time

Worked great! Its a 27mm 12 point socket to clear up any confusion, installed last night on my 2004 5.3 harmonic balancer.

Worked great for my project motor iam building

great quality, American made Forged bolt. Worked great to replace my stock bolt and can be reused, if I remember correctly a 12 point 1-1/16th socket fits it. quality product and a must buy especially if you work on your engine alot or are doing a rebuild to any GM LS engine

Would have given 5 stars but $40 for a bolt is riculouis.

Replaced the harmonic balancer on my 2000 corvette because the stock bold was leaking. The original GM bolt is a torque to yield bolt which is a one time only use item. This ARP bolt is not like that and can be reused. Literally just use the lube on the bolt and face, then torque it to 235 ft/lbs. NOTE: You must have a 12-point 1 1/16 socket to install this bolt. If it is not 12-point, it wont fit at all!
