Ratech: Precision-Engineered Small Parts for Automotive Axles

Ratech has been a focused, specialist manufacturer of small parts for automotive and light truck axles since 1999. Based in Ohio, the company occupies a unique position in the drivetrain aftermarket: rather than spreading across dozens of product categories, Ratech does one thing exceptionally well — designing and manufacturing the precise, small-but-critical components that determine whether an axle rebuild succeeds or fails. Axle shaft bearings, shims, crush sleeves, seals, and gaskets are the backbone of Ratech's catalog, and each part is made in the USA to exacting tolerances.

What sets Ratech apart is a philosophy that is rare in the aftermarket world: the engineers and technicians behind these products actually use them on their own vehicles. That hands-on commitment to quality means every component is evaluated not just on a spec sheet, but under real-world conditions on the street and at the track. This approach has built a loyal following among professional builders, restoration specialists, and serious performance enthusiasts who know that the smallest parts can make the biggest difference in a differential rebuild.

Ratech serves a wide range of applications — from original equipment manufacturing (OEM) replacement work to racing builds and classic vehicle restoration. Their catalog covers popular domestic platforms from GM and Ford, with differential pinion shims and bearing components available for a broad spectrum of axle housings. Whether you're setting pinion depth on a GM 10-bolt or dialing in backlash on a Ford 8.8", Ratech provides the precision hardware to do the job right.

The brand's complete ring and pinion installation kits are a standout offering, bundling together the bearings, crush sleeve, gaskets, hardware, seals, shims, and marking compound needed for a full differential rebuild — taking the guesswork out of sourcing individual components. For builders working on driveline upgrades, Ratech also offers drive shaft pinion yoke components and seals to complement a complete axle service.

For those refreshing worn wheel ends, Ratech's wheel bearing kits deliver the same commitment to fit and finish that defines the rest of their lineup. With an average customer rating of 4.68 across hundreds of reviews, Ratech's reputation for quality and consistency speaks for itself — making them a trusted name for any shop or enthusiast tackling drivetrain work.
