Wavetrac Limited Slip Differential for 1030/1031 Volvo Axles

These differentials are gear type but have enhancements to prevent a loss of traction that can happen if one drive wheel is unloaded with a typical gear type (Torsen, True-Trac, Quaife) differential.  They are compatible with all Solid axle RWD Volvo's that use the 1030/1031 differential.      The speedometer tone ring adapter allows for the factory diameter tone ring used on the g80 rear differentials to be installed onto the Wavetrac.  You can select the correct number of windows or tones with the dropdowns.  Typically ABS cars have the 48 tooth count tone rings and electric speedometer non-abs cars have the 12.     • Innovative: Patented Wavetrac® design automatically improves grip in low traction conditions. This feature is truly innovative and unlike any other torque biasing diff design. • Superior Materials: 9310 steel gears run in case-hardened billet or forged steel bodies. ARP® fasteners used throughout. • Maintenance Free: As supplied new, the Wavetrac® differential will perform a lifetime of service without maintenance or rebuilds. • Customizable: If desired, you can alter the diff’s behavior to suit your needs using optional components. • Limited LIFETIME Warranty: All Wavetrac® differentials include a transferable, Limited Lifetime Warranty.
