ARP 02A/02J Differential Bolt Set is designed specifically for VW Mk4 Golf '99-06, Jetta '99-'05, and Beetle '98-'09 with Wavetrac® Differential Types 02A/02J. Since the factory differential and ring gear are riveted together at the factory, when installing a Wavetrac« differential or a new ring and pinion in your 020, 02A, 02J or 02M transmission, you must drill out the rivets and replace them with special bolts and nuts. These are available from Volkswagen and also other aftermarket sources. After losing confidence with the quality and/or having been dumbfounded by the outrageous prices for these parts from these sources, Autotech decided to now offer the highest quality bolt sets available for your differential installation. Produced by ARP, the world leader in high grade fasteners, these bolt kits are made from certified CHQ 8740 Chrome Moly material (rated well above aircraft quality). Threads are rolled after heat treat ensuring the finest threads that can be torqued more accurately without binding. The splines on ARP bolts are sized correctly for the crucial press-fit into the differential flange. ARP 12-point nuts are rated at 180,000 psi or better. Bottom line: you won't find a better bolt set. You're buying the best differential available... now buy the best bolts to hold it!
