New & Improved! Our custom Carbon Clutch & Spring upgrade kit has been utilized by many high horsepower and drag racers to save their Getrag differentials and make them stronger. The Getrag is a great differential but we've seen numerous customers wear out their diff's in just a few trips to the drag strip. You may have already burnt up your differential's clutches and not even know it. Most Getrag failures consist of the clutches failing turning your rear into an open diff, causing you to spin one tire.
HHP sponsored customer Jeff S., aka, "budoboy" shows how he installed this kit:
