Moser Engineering: Built by Racers, Proven on the Street and Strip

Moser Engineering has been one of the most trusted names in American-made rear-end and drivetrain components since its founding in 1982. The company's origin story is as grassroots as it gets: Moser Engineering was started by Greg Moser, a racer who resplined a pair of axles and, in doing so, launched what would become a leading aftermarket performance brand. Headquartered in Portland, Indiana, the company has built its reputation on a straightforward but powerful promise — supply the highest quality, American-made parts with some of the fastest custom build times in the industry.

A Complete Drivetrain Ecosystem

What began as a focused axle shop has evolved into a comprehensive drivetrain resource. Today, Moser Engineering's catalog spans rear end assemblies, axle shafts, axle shaft bearings, wheel lug studs, drive shaft pinion yokes, differential covers, C-clip eliminators, spools, and complete housing-and-axle packages. Whether you're building a dedicated drag car, a weekend muscle car, or a daily-driven performance truck, Moser offers components engineered to fit the application precisely.

Moser's axle shafts are a cornerstone of the lineup. Manufactured from premium alloy steel — including 1541H and custom alloys — and available in a wide range of spline counts and lengths, these shafts are designed to handle the demands of both street and competition use. Because many of their axles are built to order, Moser can accommodate applications that off-the-shelf parts simply can't address. This custom-build capability, combined with quick turnaround times, is a major reason builders and racers continue to return to the brand.

Attention to Every Detail in the Drivetrain

Moser understands that a rear end is only as strong as its weakest component. That's why their product range extends to supporting parts like wheel lug studs — grade 8 press-in units engineered specifically for use with Moser axle flanges — and axle shaft bearings built to exacting tolerances for long service life. Their drive shaft pinion yokes are precision-machined in steel and come with all required hardware, making them a direct, reliable upgrade for popular rear end platforms including Ford 9-inch, GM 12-bolt, Dana 44, and more.

Rounding out the rear end story are Moser's differential covers, which combine functional protection with a clean aesthetic in a powder-coated finish. Available for common applications like the Chevy 12-Bolt and Dana 60, these covers are a natural complement to any Moser rear end build.

Made in America, Built for Performance

Moser Engineering's commitment to domestic manufacturing isn't just a marketing point — it's central to their quality control philosophy. Every component is produced with advanced machining processes and inspected to ensure durability and dimensional accuracy. For enthusiasts who want peace of mind knowing exactly where their parts come from and how they're made, Moser Engineering stands as one of the industry's most compelling choices.
