D-Rex
Auburn Gear, Inc is proud to announce the introduction of its' D-REX Program. D-REX stands for Differential Replacement EXchange Program. Auburn Gear's Limited Slip Differentials are designed and manufactured with an unique and robust cone clutch mechanism. (See the figure below.) However, due to the matching of the side gear/cone clutch assembly during machining and assembly, this makes the differential case and side gear/cone clutch mechanism a matched set and therefore non-rebuildable. All other components within the Auburn Gear differential are replaceable and service kits are available.

Best Guarantees in the Industry - we back up our performance advantages by offering the best warranty in the business: a one-year warranty, plus an additional four years of  coverage. D-REX stands for Differential-Replacement EXchange. We will replace your unit, no matter the reason, within the first 4 years after purchase for the price of a competitor’s clutch pack. Every part you get will be brand new–the unit comes assembled, tested, certified, ready for installation. No more rebuilding and mixing old worn parts with new parts!
