Enjoy muscle car-era acceleration in your C4 Corvette! Whether you're looking to add low-end performance to your Corvette or would like to cruise comfortably at 70 MPH, Zip has the right Corvette differential for your 1985-1996 manual transmission equipped Corvette.

Built in-house by our own skilled technicians, each Dana 44 Corvette differential core is inspected, cleaned and reassembled using all-new parts including a performance 3.90 ring & pinion gear set, Timken carrier and pinion bearings, OE-style positraction clutch packs and pinion/side yoke seals. New ring & pinion gears are matched sets and properly set-up to eliminate any unwanted "whining" often found with worn-out gear sets.

All Zip Corvette differentials are sold on exchange. Add $1800.00 refundable core charge if 1985-1996 Corvette Dana 44 differential core does not accompany order. Cores must include a rebuildable carrier that is not cracked or hallowed out at the center pin and Dana 44 housings must not be broken or welded on. Call your Zip sales representative for details on core charge refunds.

All rebuilt 1984-1996 Corvette differentials are backed by Zip's satisfaction guarantee and include a 3-year unlimited mileage warranty against defects in materials and workmanship. Does not include racing or abusive applications.

Zip Corvette recommends a specific break-in procedure when installing a rebuilt differential into your Corvette. Failure to follow the break in procedures will allow excessive heat to build up causing a less than desirable pattern on the face of the gear resulting in noise and eventually a possible gear failure. Zips 3-year unlimited mileage warranty is contingent upon following the procedures outlined in our Differential Break-In Procedures to safeguard your Corvettes differential. Break-in procedures and differential core return instructions are found under our product download tab.
