Wavetrac Limited Slip Differential Chevrolet Corvette / Z06 (C5/C6) Automatic Transaxle Rear

Wavetrac Limited Slip Differential - Chevrolet Corvette / Z06 (C5/C6) - Automatic Transaxle Rear

The Wavetrac is a helical gear, torque-biasing limited slip differential that directly replaces the factory differential in the rear automatic transaxle of the Chevrolet Corvette and Z06 (C5 and C6). 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: Two special C-clips are included. The OEM stub shaft C-clip grooves must be modified to accept them. C6 Z06 owners also need one special (3mm wider) Timken bearing, part 387A-382-S, not included.

Fitment & Identification

• Vehicles: Chevrolet Corvette (C5/C6); Corvette Z06 (C5/C6)
• Gearbox: automatic transaxle
• Position: Rear
• OEM stub shaft C-clip groove modification required
• C6 Z06: 1 x Timken 387A-382-S bearing required (not included)

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
• New carrier bearings are recommended when the differential is changed
• Gear oil to factory specification (see below)
• OEM stub shaft C-clip groove modification
• C6 Z06 only: 1 x Timken 387A-382-S bearing (3mm wider)

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.
