Yukon 2007-2017 Jeep JK (Non Rubicon) Re-Gear Kit w/Covers - Dana 30/44 5.13 24 Spline - Front & Rear

The Yukon YGK014STG2 Stage 2 Re-Gear Kit is a complete front + rear differential upgrade package for Jeep Wranglers using Dana 30 front & Dana 44 rear setups. It includes matched ring & pinion gear sets, overhaul kit components, and Yukon heavy-duty diff covers. Designed for builds using 4.88 gearing and 30-spline front pinions, this kit addresses both performance and reliability. 

Kit Contents & Specifications

• Ring & Pinion Gear Set (Rear): 4.88 ratio for Dana 44 rear diff
• Pinion Spline Count: 30-spline for front Dana 30 diff
• Overhaul Kit: Bearings, seals, shims, and hardware for both front and rear diffs
• Diff Covers: Heavy-duty Yukon covers included for both front and rear differentials

Fitment & Compatibility

• Intended for Jeep Wrangler models that use a Dana 30 front axle and a Dana 44 rear axle
• Designed around 30-spline front pinions for compatibility with many factory Wrangler builds

Why Use This Package?

• Matched Gear Set Across Axles: Balanced front and rear gearing helps maintain driveline stability and performance.
• Complete Install Solution: Everything needed (covers, hardware, overhaul kit) included—no parts missing mid-build.
• Performance Upgrade: 4.88 gearing is an excellent choice for Jeep builds running larger tires or for trail/overlanding use.
• Build Efficiency: Purchasing one kit for both axles simplifies sourcing and reduces build complexity.

Installation & Recommendations

• Correct setup of backlash and pinion preload is critical—even with a complete kit, tuning per axle spec is needed.
• Use recommended gear oil and follow break-in protocols to ensure longevity.
• Evaluate U-joint angles, driveshaft length, and carrier bearing conditions during the upgrade.
• Always test fit covers and differential alignment before final torque.
