M66 Wavetrac Limited Slip Differential

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.
