USA Standard Gear Transfer Case

About USA Standard Gear

USA Standard Gear has built a strong reputation among professional mechanics and serious enthusiasts as a go-to source for drivetrain and transmission components that meet or exceed original equipment specifications. The brand's philosophy is straightforward: deliver parts that are affordable without sacrificing the quality standards that demanding applications require. Whether you're rebuilding a weekend off-roader, restoring a classic truck, or maintaining a working vehicle, USA Standard Gear offers a comprehensive lineup engineered to perform.

Drivetrain Expertise You Can Count On

USA Standard Gear's catalog spans a wide range of drivetrain categories, including ring and pinion gear sets, differential rebuild kits, axle shafts, and driveshafts for a broad array of domestic and import applications. Their products are manufactured to tight tolerances, helping ensure proper fitment and long service life — a critical factor when working with components that bear the full load of an engine's power output.

One of the brand's standout strengths is its deep coverage of manual transmission components. Rebuilding a manual transmission demands precision-matched parts, and USA Standard Gear delivers with their Manual Transmission Rebuild Kits — comprehensive kits that include the key components needed to restore a transmission to like-new function. For shops or DIYers tackling individual component replacement, the brand's Manual Transmission Gears provide direct-fit options across a wide range of popular transmission models, helping you source the exact gear you need without compromise.

Seals and bearings are often overlooked during a rebuild, yet they are critical to keeping a transmission running smoothly and leak-free for the long haul. USA Standard Gear addresses this with their Manual Transmission Bearing and Seal Overhaul Kits, which bundle the necessary bearings, seals, and related hardware into a single convenient package — saving time and reducing the risk of missing a critical component during assembly.
