05 Heavy Duty 3.90 Differential (New)

Give your Corvette serious muscle car-style acceleration! Available for 6-speed and automatic C6's. Performance ratio gear sets and heavy-duty output shaft will guarantee quicker acceleration while making sure your differential is bullet proof.

Automatic equipped Corvettes require computer tuning for installation, contact a Modified sales representative for more information. 6-speeds can benefit from quicker acceleration without any modification to your Corvette.

NOTE: Modified Corvettes, LLC recommends a specific break-in procedure when installing a new or rebuilt Getrag differential into your C5 or C6 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.
