Wavetrac Limited Slip Differential - VW Golf / Jetta (Mk4/Mk5/Mk6/Mk7) - 02J-B 5-Speed / 02S 6-Speed Manual
The Wavetrac is a helical gear, torque-biasing limited slip differential that directly replaces the factory differential for the VW Golf and Jetta Mk4 (2004+) to Mk7 with the 02J-B 5-speed or 02S 6-speed manual. 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: Suits the later 02J-B gearbox (Mk4 2004+ and Mk5-Mk7) and the 02S 6-speed, with a 113mm ring gear ID. The early 02J to 2004 uses a 114mm ring gear ID - see 10.309.180WK. Includes an ARP ring gear bolt kit.
Fitment & Identification
- Vehicles: VW Golf / Jetta Mk4 2004+ & Mk5-Mk7 (02J-B 5-Speed Manual / 02S 6-Speed Manual)
- Gearbox / axle: 02J-B 5-Speed Manual / 02S 6-Speed Manual
- Position: Gearbox (transaxle)
- Includes ARP ring gear bolt kit
- The 180WK 02J (to 2004) has a 114mm ring gear inner diameter
- The 181WK 02J-B (after 2004) has a 113mm ring gear inner diameter
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 You'll Also Need
- Your factory ring gear, transferred from the original differential
- The factory VW/Audi ring gear is riveted to the open differential - the rivets must be drilled out and the ring gear bolted to the Wavetrac with ARP bolts
- 02J-B / 02S install kit (10.398.002K - carrier bearings, end cover gasket, speedo drive gear and O-rings) recommended
- Gear oil to factory specification (see below)
Installation
Installation by a professional driveline specialist is always recommended. The ring gear is transferred to the Wavetrac and backlash and bearing preload are set to factory specification. 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.
