When installing a Wavetrac differential or a new ring and pinion in your 020, 02A, 02J, 02Q, or 02M transmission, it is necessary to remove the rivets that hold together the factory differential and ring gear. These rivets should be replaced with special bolts and nuts, which can be obtained from Volkswagen or other aftermarket sources. At Autotech, we offer high-quality bolt sets produced by ARP, the world leader in high-grade fasteners. Our bolt kits are made from certified CHQ 8740 Chrome Moly material to ensure the finest threads that can be torqued accurately without binding. The splines on our bolts are correctly sized for the press-fit into the differential flange. We use ARP 12-point nuts rated at 180,000 psi or better for added strength and durability. If you are in search of a top-of-the-line differential, it is only fitting to use the best bolts to hold it in place.
