We have seen broken diff hats and broken B Series Diffs (6spd RZ). Axle Tramp is the enemy of traction. It overloads components by hammering the drive train until it breaks. It's causes are largely due to harmonics in the IRS setup and low traction conditions.
We broke both diffs under power when changing from 2nd to 3rd gear while losing traction due to a combination of power, not so good tyres and road surface. Once it gripped, it chipped the teeth on the crown and pinion wheels. Racetune have engineered a solution based on our own experience and existing products and have made it accessible to all.
Factory bushes are nearly impossible to find in stock world wide at the same time and are more expensive! We have engineered a unique solution with the ease of installation with hand tools.
