A number of high performance models are available for specialist applications such as drag racing, competition rock crawling and heavy tank-track type snow equipment.
Designing locking differentials for applications such as these presented our engineering team with some significant challenges. Not only did the locker have to be able to withstand more traction torque than a standard differential, but it had to also tolerate massive amounts of torque handling facilitated by the substitution of custom made high alloy aftermarket axle shafts, which are cut with larger than standard diameter splines. This was particularly difficult owing to size constraints dictated by the original axle assembly. ARB met this challenge using a combination of aerospace grade materials, and a design guided by the results of high torque testing using computer simulations and destructive testing.
