Moser Engineering opened its doors in 1986 and has spent the past 40 years producing some of the best driveline components on the market. To celebrate its 40th anniversary, Moser is offering free assembly on all of its popular MusclePak rearends in the month of May.

The MusclePak lineup covers a wide range of applications. Each rearend is designed and manufactured in the USA, with Moser even utilizing its own casting boxes to produce several variations of these high-performance rearend housings.

If you’re looking for a strong 9-inch-style rearend at a competitive price point, Moser’s John’s Industries unit is an excellent option. This MusclePak rearend is available in multiple configurations as a bolt-in solution for a variety of applications. Moser also offers a 12-bolt MusclePak rearend for those seeking a durable, direct-replacement upgrade for multiple applications.

For builders chasing big horsepower, Moser’s MusclePak lineup includes even stronger solutions. The Moser M88 is an upgraded version of Ford’s iconic 8.8 rearend, offering improved strength and durability. For extreme performance applications, Moser also offers a fabricated M9 (9-inch) MusclePak rearend, as well as a Mopar 8 ¾-style fabricated rearend designed to handle serious traction demands.

Keep in mind, the free assembly offer on MusclePak rearends is only available through May. You can view eligible rearends and learn more about this limited-time promotion on Moser Engineering’s website.
