Differential Shim Kit

The Frankland Racing Differential Shim Kit (MPN: KT0445) is a precision steel component designed for racers and high-performance enthusiasts who demand reliable gear mesh control in quick-change differential systems. This shim kit allows you to fine-tune backlash and preload settings, critical adjustments that directly impact power delivery, tire wear, and differential longevity under racing conditions. Whether you're campaigning a circle track car, bracket racer, or street performance build, proper differential shimming ensures consistent handling and maximizes the lifespan of your drivetrain components.

Manufactured from durable steel, the differential shim kit provides the precision thickness control needed to achieve exact gear mesh geometry in Frankland Racing's Superlite Quick Change differential housings. Shims work by adjusting the axle carrier bearing preload and ring gear-to-pinion distance, allowing you to dial in the optimal contact pattern and load distribution across gear teeth. The compact, lightweight design (0.07 lbs) makes it easy to carry in your pit kit, and the precisely dimensioned shims (2.6 x 0.4 x 4.9 inches) fit seamlessly into Frankland's quick-change platform without modification or additional fabrication.

This shim kit is essential for owners of Frankland Superlite Quick Change differentials who need to maintain or restore proper backlash and preload after assembly or repair. Track mechanics and tuners rely on differential shim kits to troubleshoot noise, vibration, or premature wear—common signs of incorrect mesh geometry. Installation requires basic differential knowledge and proper measurement tools, but the results deliver noticeable improvements in power transfer efficiency and differential reliability. Keep a kit on hand as part of your racing maintenance program.
