Wavetrac Limited Slip Differential VW Golf R (Mk7/Mk7.5/Mk8) / Audi S3 (8V) / TTS (8S) 0AV (MQB) AWD Rear

Wavetrac Limited Slip Differential - VW Golf R (Mk7/Mk7.5/Mk8) / Audi S3 (8V) / TTS (8S) - 0AV (MQB) AWD Rear

The Wavetrac is a helical gear, torque-biasing limited slip differential that directly replaces the factory differential for the VW Golf R (Mk7 / Mk7.5 / Mk8), Audi S3 (8V) and TTS Quattro (8S) MQB AWD rear axle. Unlike conventional helical LSDs, Wavetrac's patented design keeps driving the wheel with grip even when the other wheel is unloaded or in the air - where other helical diffs behave like an open diff. There are no clutch packs to wear, adjust or rebuild.

Note: Requires custom machining of the welded factory ring gear. ARP ring gear bolt set included.

Fitment & Identification

• Vehicles: VW Golf R AWD (Mk7 / Mk7.5 / Mk8); Audi S3 Quattro (8V); Audi TTS Quattro (Mk3 8S / FV)
• Gearbox / axle: 0AV (MQB) rear final drive
• Position: Rear
• Application: 0AV MQB platform rear differential
• Factory ring gear is welded - custom machining required

Please confirm your gearbox or axle code, final drive ratio and model year before ordering. If you are unsure, send us your VIN and gearbox/axle code and we will confirm fitment.

What's Included

• Wavetrac differential assembly (carrier with internal gear set)
• ARP ring gear bolt set

What You'll Also Need

• Your factory ring gear, machined from the welded factory differential
• New carrier bearings are recommended when the differential is changed
• Gear oil to factory specification (see below)

Installation

Installation by a professional driveline specialist is always recommended. The welded factory ring gear must be custom machined off the original differential before it can be bolted to the Wavetrac with the supplied ARP bolts. Torque the ring gear bolts to 12 ft-lb (16 Nm) with Loctite 242 (blue) - red Loctite is not recommended. No break-in is required for the Wavetrac itself - follow the break-in procedure only if a new ring and pinion is fitted at the same time.

Gear Oil

• Use the gear oil specified by your vehicle manufacturer - the Wavetrac is compatible with virtually all factory-fill gear oils
• Avoid gear oils with limited slip (friction modifier) additives - they reduce the friction a helical differential relies on
• Do NOT use Red Line ShockProof or similar oils - this voids the Wavetrac warranty
• For racing, Wavetrac recommends Motul synthetic high-performance gear oils

Strength & Maintenance

Wavetrac differentials use high-strength 9310 alloy steel gears in case-hardened billet or forged steel housings, assembled with ARP fasteners. In almost any gearbox or axle, the Wavetrac is not the limiting factor in torque capacity. There is no scheduled maintenance and no rebuilds are required.

Warranty

Wavetrac limited lifetime warranty against defects in manufacture, material, workmanship and wear-out, when used in the application it was designed for - including racing - and transferable to subsequent owners. Excludes differentials that are incorrectly installed, fitted to the wrong application, modified, or run in ShockProof-type oil. Proof of purchase from an authorised Wavetrac dealer is required.
