The 10 Hole Pinion Support Shim Pack Kit from Moser Engineering is a critical precision component for builders and mechanics working with high-performance differential assemblies. This kit addresses one of the most overlooked yet essential aspects of differential setup: controlling pinion bearing preload and ensuring proper gear mesh geometry. Whether you're assembling a competition-grade differential, rebuilding a worn unit, or fine-tuning an existing setup for maximum reliability, pinion shims are non-negotiable for achieving correct backlash and load distribution across the ring gear.
Pinion support shims work by controlling the position of the pinion bearing cage relative to the ring gear, directly affecting both gear mesh depth and bearing preload characteristics. The 10-hole design of this kit matches Moser Engineering differential housings and provides multiple shim thickness options, allowing technicians to dial in exact preload specifications without guesswork. Proper shimming prevents catastrophic failures such as premature bearing wear, gear tooth stripping, and excessive noise—all common results of incorrect pinion geometry. These shims are manufactured to tight tolerances and work in conjunction with your bearing setup to maintain the precise contact pattern required for efficient power transfer and longevity.
This kit is essential for anyone building or rebuilding a Moser Engineering differential housing or working with compatible aftermarket components. Professional builders, race teams, and serious enthusiasts trust Moser Engineering products for their uncompromising quality and accuracy. Installation requires proper measurement tools, dial indicators, and a methodical approach to achieve the manufacturer's specified preload range. When installed correctly as part of a complete differential assembly procedure, the 10 Hole Pinion Support Shim Pack Kit ensures your differential operates at peak efficiency while maintaining the reliability demanded by street and track applications alike.
