Pricing is on an exchange basis. We build and ship you a differential, you install it, then ship us the core back on or in the same box or pallet. If we do not receive a rebuildable core back within 30 days, we will charge you a minimum of $750 for the differential core. Contact us if you do not have a core differential.
Prices subject to change.

These packages will give you an idea of what we offer. We are always coming up with new upgrades, so don't think of this as a list of all that we can do. Look at the differential parts page for upgrades you can add to these packages. If you have a custom project or something else in mind, just give us a call.

$995.00 - Quaife ATB Differential upgrade for C5/C6 Corvettes - The Quaife torque biasing differential enables your car to accelerate quicker and corner faster. The Quaife Differential powers both drive wheels under nearly all conditions, instead of just one. With an ordinary open differential, standard on most cars, a lot of precious power is wasted during wheelspin under acceleration. This happens because the open differential shifts power to the wheel with less grip (along the path of least resistance). The Quaife, however, does just the opposite. It senses which wheel has the better grip, and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.

(Includes Grand Sport with manual transmission)
