VAG Built Axles

Regal Autosport is offering machining and installation services to customers to VAG rear axles! 

VAG rear axles on the VW/AUDI MK7R/8V  were manufactured with a friction-welded ring gear and differential. To fit a performance Limited Slip Differential, like the Wavetrac, the ring gear needs to be separated, machined, drilled and tapped to accept bolts, to then attach it to the Wavetrac LSD. 

3 options explained: 

1) Ring gear separation, drilling, tapping of customer suppled ring gear and differential

You deliver to us your single piece ring gear and differential, we separate the ring gear from the differential, machine, drill and tap to accept bolts and a Wavetrac LSD. We ship the ring gear to you. 

2) Ring gear separation, drilling, tapping and install into customer supplied usable axle (excluding Wavetrac)

We take your usable axle you supply, deconstruct, take your original, single-piece ring gear and differential, separate it from the differential, machine, drill and tap to accept bolts, you supply us with the correct Wavetrac LSD, and we fit it to the axle. We ship the built axle to you. 

3) Supply and fit Wavetrac LSD into customer's supplied axle (pending condition) 

We take your usable axle you supply, deconstruct, take your original, single-piece ring gear and differential, separate it from the differential, machine, drill and tap to accept bolts, supply a Wavetrac LSD, and fit to the axle. We ship the built axle to you. 

Applicable models: 

0AV-W = MK7/7.5 GOLF R, 8V S3

Before ordering, we recommend you send your VIN to check if this item applies to your vehicle. Due to manufacturing and design variances across years, we also recommend that you provide us accurate measurements of the factory ring gear and differential assembly before purchase so we can confirm fitment.
