Moser Engineering’s MUSCLEPAK Rearends Are Drop ‘n’ Go

When it comes to selecting the right rear end for your muscle car, there are seemingly endless choices when it comes to spline count, gear ratio, and differential options. For the really wild custom cars, only a custom rear end will do. But for those of us doing something a bit more standard, but with a lot more power than stock, Moser Engineering offers a wide range of rear end solutions.

We’ll be discussing their Muscle Pak line of Made in America complete rear end packages. They come in three flavors; 9-inch, 12-bolt, and Dana 60 models.

All three rear ends are offered with a wide variety of options, from the economy disc brake upgrade (for those of you who feel the stock drums just aren’t enough) to the color you want the housing painted. Moser also offers a range of gear options, from high-speed 3.00:1’s on the Ford 9-inch to rock-crushing 5.13:1 gears for the Dana 60.

You can also choose the type of differential you want, depending on your application. But the best part of this whole kit is once you’ve decided what options you need for your Moser Muscle Pak rear end, it will be a bolt-in upgrade once it arrives, and Moser has built up a reputation as a reliable builder of badass rear ends. You can trust your ride with Moser.
