The ubiquitous GM 10-bolt rear—in 8.2- and 8.5-inch ring gear sizes—came standard in many GM cars from the ‘60s through the ‘80s. While not known especially for ultimate strength, they can more than hold their own in most high-powered street vehicles, and with a little care, can be made into excellent performers. On the negative side, the GM 10-bolt uses a c-clip to retain the axles, which is a no-no in drag racing. To remedy the problem, many racers use external axle retention—called a c-clip eliminator. While these do perform the requisite safety function, they are less desirable for the street because their ball-bearing design is prone to failure and leakage. Strange Engineering has the solution with their specially designed c-clip eliminator kit (part No. A1033) which uses tapered Timken bearings. These are capable of surviving severe side loads and constant use. The kit also features two seals per axle shaft, ensuring a completely sealed axle end. Complete axle and c-clip eliminator packages are also available. The A1033 kit makes your 10-bolt a win-win scenario with low operating cost (about $180), high strength, and the ability to handle the stresses of street work.
