Description
Description
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.
