Shim Kit - Ultra Case Pinion Depth

The STRANGE Shim Kit - Ultra Case Pinion Depth is a precision adjustment component designed for differential builders and serious gear enthusiasts who demand dead-accurate pinion depth setup. Proper pinion depth determines bearing preload geometry, gear mesh contact pattern, and ultimately the longevity of your ring-and-pinion assembly. This shim kit eliminates guesswork during assembly and ensures your gears sit exactly where the manufacturer intended.

Manufactured to tight tolerances, each shim maintains flatness and dimensional consistency across the carrier bore, preventing rocking or binding. This shim kit functions as a fine-tuning instrument for setting pinion depth without trial-and-error disassembly cycles. By allowing incremental pinion positioning adjustments, the kit lets you dial in the correct bearing preload and ring gear contact pattern in one pass.

DIY builders, professional shops, and gear installers benefit most from owning this shim kit before dropping a differential on the bench. Installing shims correctly eliminates the risk of improper mesh contact—the leading cause of premature gear failure under load. Compatible with STRANGE Ultra case differentials and most other standard differential cases, this kit is essential for any serious gear installation.
