Pinion Shim Dana

The Pinion Shim Dana by MOTIVE GEAR is a precision steel differential shim engineered for Dana 30, 35, and 50 axle assemblies. This component is essential for technicians and off-road enthusiasts who need to maintain proper gear mesh alignment and backlash settings during differential rebuild or repair. Pinion shims are critical wear items that ensure optimal power transfer and extend the service life of your differential assembly.

Manufactured from high-strength steel in natural finish, this shim functions by controlling pinion depth relative to the ring gear—a specification critical to differential function and noise reduction. The shim's precise thickness and material composition allow it to maintain dimensional stability under the extreme pressures and loads encountered in differential operation. Proper pinion depth, achieved through correct shimming, prevents gear noise, premature wear, and differential failure. At just 0.02 lbs with compact dimensions of 3.25 x 0.3 x 3.35 inches, this shim integrates seamlessly into standard Dana differential housings without additional modification.

This product is ideal for mechanics performing differential service on light-duty, mid-range, and heavy-duty vehicles equipped with Dana axles—from truck builds and off-road platforms to restoration projects. Installation requires proper measurement and shim selection during assembly to achieve manufacturer-specified backlash and gear mesh contact patterns. OEM MOTIVE GEAR construction ensures compatibility with all Dana 30, 35, and 50 applications, making this shim a trusted choice for professional shops and experienced DIY builders alike.
