Shim Kit - Ultra Case Pinion Depth

The STRANGE Shim Kit - Ultra Case Pinion Depth (Part Number N1962UC) is a precision differential adjustment kit designed for fine-tuning pinion bearing preload in Strange billet and ultra case differentials. This shim kit contains eight individual shims in four graduated thicknesses—two each at 0.003, 0.007, 0.008, and 0.010 inches—allowing technicians to achieve the exact pinion depth required for optimal ring and pinion mesh geometry.

Proper pinion depth directly affects gear contact pattern, bearing preload, and differential noise levels. The shims feature a 6.480-inch outer diameter and 5.075-inch inner diameter, fitting Strange's billet and ultra case housings without modification. Each shim's thickness is precisely controlled to enable incremental depth adjustment during differential assembly or rebuild. The complete kit weighs 0.31 pounds and measures 7.4 x 10.8 x 0.55 inches, making it compact and portable for shop or field use.

This shim kit is essential for high-performance and street rod builders, differential technicians, and motorsport competitors working with Strange differentials. Whether during initial assembly, bearing preload adjustment, or ring and pinion replacement, these shims enable the precise adjustments necessary to eliminate gear whine, reduce bearing friction, and ensure proper load distribution across the gear teeth. Technicians can combine shims to achieve any depth between 0.003 and 0.037 inches in 0.001-inch increments, providing flexibility for various applications and setup requirements.
