Jeep TJ Differential Install Kit - Front + Rear - Yukon Gear & Axle - Dana 30 Front & Dana 44 Rear - 4.56in Ratio - `97-`06

Jeep TJ Differential Install Kit - Yukon Gear & Axle - Dana 30 Front & Dana 44 Rear - 4.56 Ratio ('97-'06). This complete kit supplies matched front and rear ring & pinion sets plus Yukon Master Overhaul Kits to re-gear your TJ with confidence.

Designed for Jeep TJ models with a Dana Spicer 30 front and Dana Spicer 44 rear, this Yukon package combines precision-manufactured ring and pinion gears and the comprehensive overhaul components required for a full front and rear re-gear. Yukon uses advanced heat-treating and controlled quality testing to meet fit and durability needs. The kit is ideal if you’re increasing tire size, seeking more towing capacity, or replacing worn gears. Note: if your vehicle currently runs a 3.73 ratio you will need a new rear carrier; if it runs 3.08 or 3.54 you will need new front and rear carriers to complete the swap.
