After more than fifty years’ worth of use and abuse, it can be hard to gauge the quality and correctness of factory-installed parts. Rear end housings, for example, bore the full brunt of a big-block’s brute strength but are rarely inspected for straightness or twist. As long as fluid isn’t pouring from a road rash gash, they’re usually deemed “good enough” and filled with new gears and goodies.

We wouldn’t be so trustworthy of the singular component tasked with transferring both torque and tire bounce over the span of five decades. Fortunately, Moser Engineering can put the muscular mind at ease with their brand-new 8.75 housing and axle packages. Two varieties are available to cover applications ranging from race cars to restorations.

A stamped housing (P/N 875S) would look right at home on something stealthy that requires maximum strength and a close-to-stock look. Fill/drain plugs and a back brace are optional, but a set of axles is included either way.

For those that have a little more ferocity up front, a fabricated housing (P/N 875M) might be better-suited. A little more purpose-built, it could easily cap off the back half of a pro street or drag car build.

As is the case with most Moser products, a slew of options is available to construct something totally custom if necessary. Spline count, width, bolt pattern, stud size, brakes, and powder coating are all configurable to meet the exact needs of their Chrysler customers.
