JXB Peformance Sport Differential Brace
We set out to not just make a brace, but actually make sure it did something! To do that, we made a massive test fixture complete with subframe, sport differential, axles, hubs, and a driveshaft. We then welded a 12 foot long steel tube to the driveshaft and applied force with a load cell until we broke the weakest link. With our fixture we are able to apply almost 5,000 ft-lbs of force to the rear end. Here were the results: - Test 1 - Everything stock - RH OEM axle shaft broke at 1602 ft-lbs - Test 2 - Added JXB upgraded RH axle - LH OEM axle shaft broke at 1912 ft-lbs - Test 3 - Added JXB upgraded LH axle - differential rear mounting bolts broke out of casing at 1939 ft-lbs - Test 4 - Added our differential brace - RH JXB axle shaft broke at 2296 ft-lbs - Test 5 - Repeat of 4 with new RH JXB axle - Pinion flange shaft broke at 2210 ft-lbs (possibly due to damage from snapback from previous tests when components broke suddenly) So, what does this mean? At a MINIMUM, our diff brace
