Bottom line: you won't find a better bolt set. We use ARP 12-point nuts rated at 180,000 psi or better. The splines on our bolts are sized correctly for the crucial press-fit into the differential flange. Threads are rolled after heat treat ensuring the finest threads that can be torqued more accurately without binding. Produced for us by ARP, the world leader in high grade fasteners, our bolt kits are made from certified CHQ 8740 Chrome Moly material (rated well above aircraft quality). These are available from Volkswagen and also other aftermarket sources.Īfter losing confidence with the quality and/or having been dumbfounded by the outrageous prices for these parts from these sources, we now offer what we know to be the highest quality bolt sets available for your differential installation. Its the big bolt that is right above the slave cylinder. Flywheels are either a 6-bolt or 10-bolt design, depending on the engine. 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, 02Q or 02M transmission, you must drill out the rivets and replace them with special bolts and nuts. Anyways my question is what size is that bolt that i'm missing. The 02M uses a 240mm flywheel and clutch assembly, up from 228mm on the 5-speed 02A/02J.
