M10 x 1.25mm 12-Point Chromoly Bolt Kit

The ARP 02A | 02J Differential Ring Gear Bolt Kit is engineered to provide a robust solution for replacing the often problematic VW "rivets" found on 02A and 02J transmission ring gears. Manufactured in the USA by ARP, these bolts are constructed from high-strength chromoly with a durable black oxide finish, offering a substantial yield strength of 200,000 psi. This ensures that your differential will remain securely in place, even under high-stress conditions. The kit includes all necessary hardware, such as washers, and features a 12-point head style for easier installation and torque application. The thread size is M10 x 1.25 mm, with an underhead length of 1.18 inches. This bolt kit is specifically designed for the 02A and 02J transmissions, offering a superior alternative to the factory fasteners and preventing the risk of the ring gear breaking free. However, it is important to note that early 02A transmissions with code ATA and a production number up to 12099 require the 020 gear bolt kit (part #204-3001). Always verify fitment for your specific vehicle before purchase.
