ARP Ring Gear Bolt Kit, GM 12-Bolt / 8.2" 10-Bolt, RH Thrd

Brand: Automotive Racing Products (ARP)

Ring gear bolts are subjected to incredible stresses, especially in racing applications. All of the torque going through two tire contact patches has to first pass through the ring gear bolts. A drag launch represents an explosive shock load, while road racing generates cyclical loads with upshifts and downshifts. You need bolts that are up to the job!

ARP Pro Series ring gear bolts are forged from 8740 chrome moly alloy steel, then heat-treated to 200,000 psi tensile strength. Threads are then rolled (not cut) after heat treatment (not before) for superior strength and resistance to fatigue.

This bolt kit fits all GM 12-bolt ring gears as well as 8.2" 10-bolt ring gears. Includes twelve 3/8-24 x 0.800" bolts with right hand threads. (10-bolt ring gears will be left with 2 extra bolts.)

Installation Note: These bolts are engineered for use without washers. Installing them with washers may cause the bolts to loosen, with potentially catastrophic results. Use Loctite 242 (Blue) Threadlocker (Part No. LT-24221, sold separately) on the bolt threads and ARP Ultra-Torque Assembly Lube (Part No. ARP100-9908, sold separately) under the bolt head.

Application Note: GM 7.2", 7.5", 7.625", and 8.5" 10-bolt ring gears use larger bolts with left-hand (reversed) threads. These ring gears require the ARP Ring Gear Bolt Kit for GM 10-Bolt Ring Gears, Part No. ARP230-3002.
