Yukon Gear & Axle YGK012STG3 Stage 3 Re-Gear Kit Dana 30/44 4.56 Ratio with Diff Covers & Chromoly Axles

The Yukon Gear & Axle YGK012STG3 Stage 3 Re-Gear Kit is the ultimate complete solution for Jeep JK differential upgrades, delivering everything needed to re-gear both front Dana 30 and rear Dana 44 differentials in one comprehensive package. This premium kit includes front and rear ring and pinion gear sets in a 4.56 ratio, master overhaul kits with all necessary bearings and installation components, heavy-duty Yukon Hardcore differential covers, and high-strength 4340 chromoly front axle shafts with 24-spline configuration.

Complete Stage 3 Package Includes:

• Front and rear Yukon ring and pinion gear sets (4.56 ratio) engineered with advanced heat-treating and precision manufacturing
• Master overhaul kits with premium bearings, seals, pinion nuts, crush sleeves, marking compound, and all small installation parts
• Yukon Hardcore differential covers for both front and rear axles, constructed from thick-walled nodular iron with powder coat finish
• Chromoly front axle shafts (4340 alloy) for superior strength and durability over stock axles
• Magnetic drain plugs to collect metallic particles and protect gears
• High-strength steel fasteners for secure installation

Performance Benefits:

The 4.56 gear ratio is ideal for enhancing off-road performance, restoring power lost to larger tires (typically 33-35 inch diameter), improving crawl ratio for technical terrain, and increasing towing capacity. Yukon ring and pinion sets add power and performance while keeping gears running cooler and quieter than stock configurations.

Premium Construction & Protection:

The Yukon Hardcore Diff Covers are constructed from thick-walled, high-strength nodular steel to protect lockers, gears and axles from the most extreme hits in off road driving. Contoured inner surfaces circulate oil more rapidly for faster cooling, while the black powder coat finish provides long-lasting corrosion resistance. The included 4340 chromoly front axles deliver substantially greater strength than factory axle shafts, reducing the risk of breakage during aggressive off-road use.

Quality Engineering:

Yukon Gear & Axle high-performance ring and pinion gear sets are the benchmark of quality in the automotive gear industry, using state-of-the art design, advanced heat-treating techniques, and leading-edge quality testing processes to ensure optimal performance and longevity. Each component is manufactured to meet or exceed OEM specifications for quiet operation and durability.

Important Installation Notes:

Professional installation is strongly recommended for proper gear setup and optimal performance. Differential oil is not included and must be purchased separately. If upgrading from factory 3.21 gears, a new carrier case may be required for the front Dana 30 axle. This kit is designed specifically for Jeep JK Wrangler models with non-Rubicon Dana 30 front and Dana 44 rear axles. Yukon Gear & Axle backs this kit with their comprehensive Y.E.S. (Yukon Extended Service) Plan, offering lifetime coverage for as long as you own your vehicle.
