Yukon Jeep TJ & Cherokee XJ Complete Regear Kit - Dana 30 / AMC 35
YGK005
The Yukon Jeep TJ Complete Gear & Install Kit combines matching front and rear ring and pinion gear sets with master overhaul kits for Jeep Wrangler TJ and compatible Cherokee XJ models equipped with a Dana 30 front axle and AMC Model 35 rear axle. Regearing is one of the best ways to restore lost pulling power after installing larger tires, improve throttle response, and get your Jeep back into a more useful operating range. This complete package takes the guesswork out of sourcing the major components needed to regear both axles together.
Available in 4.56 and 4.88 ratios, this Yukon package is a practical upgrade for trail Jeeps running larger tires, added armor, or heavier off-road equipment. Numerically higher axle ratios increase torque multiplication, helping improve low-speed control, climbing performance, and transmission shift behavior. Both gear sets are matched to the selected ratio, and the included master overhaul kits provide the bearings, races, seals, shims, and setup components needed for installation. Depending on your existing factory gear ratio, replacement differential carriers may also be required.
Includes:
- (1) Dana 30 Front Ring & Pinion Gear Set
- (1) AMC Model 35 Rear Ring & Pinion Gear Set
- (1) Dana 30 Front Master Overhaul Kit
- (1) AMC Model 35 Rear Master Overhaul Kit
- Matching Front & Rear Gear Ratios
- Bearings, Races, Seals, Shims & Setup Components Supplied with the Master Overhaul Kits
Available Gear Ratios: 4.56 or 4.88
Important: This kit is designed for compatible Jeep TJ and Cherokee XJ models with Dana 30 front and AMC 35 rear axles. Vehicles currently running 3.54 gears require a replacement front carrier. Vehicles currently running 3.07 gears require replacement front and rear carriers. Replacement differential carriers are not listed as included.

FAQ
What comes in the Yukon Jeep TJ complete regear kit?
This package includes matching front and rear ring and pinion gear sets along with master overhaul kits for both axles. The front gears are designed for the Dana 30, while the rear gears are designed for the AMC Model 35. The overhaul kits provide the bearings, races, seals, shims, and related setup components needed for installation.
Should I choose 4.56 or 4.88 gears for my Jeep TJ?
Both ratios help restore lost pulling power after larger tire upgrades. The right choice depends on tire size, engine, transmission, vehicle weight, and how much highway driving you do.
| Gear Ratio | Common Applications |
|---|---|
| 4.56 | 33"–35" tires, mixed street/trail driving, and improved pulling power |
| 4.88 | 33"–35" tires, heavier trail builds, and greater low-speed torque multiplication |
Builder Note: These are general starting points rather than fixed tire-size recommendations. Engine output, transmission gearing, highway RPM, and intended use should all be considered before selecting a ratio.
Do I need new differential carriers when regearing my Jeep?
That depends on your current gear ratio. Jeeps equipped with 3.54 gears require a replacement Dana 30 front carrier when upgrading to the ratios in this package. Jeeps equipped with 3.07 gears require replacement front and rear carriers. Verify the existing carrier breaks before ordering.
Will this kit fit a Jeep TJ with a Dana 44 rear axle?
No. This package is designed specifically for a Dana 30 front axle and AMC Model 35 rear axle. If your TJ has a Dana 44 rear axle, you'll need a different rear gear set and installation kit.
Does the kit include bearings, seals, and installation components?
Yes. The included front and rear master overhaul kits supply the bearings, races, seals, shims, and related setup components needed for the regear. Replacement differential carriers and any additional axle repair components are sold separately.
Will regearing improve performance with larger tires?
Yes. Larger tires effectively raise the overall gearing, which can make acceleration feel sluggish and reduce low-speed control. Numerically higher axle ratios help restore torque multiplication, improve throttle response, and keep the engine and transmission operating in a more useful range.
Can I install this kit myself?
Ring and pinion installation requires specialized tools and experience setting pinion depth, bearing preload, backlash, and gear tooth contact patterns. Incorrect setup can cause gear noise, premature wear, or failure. We recommend professional installation unless you have experience rebuilding differentials.
Do the front and rear axle ratios need to match?
Yes. Front and rear differential gear ratios must match before operating the vehicle in four-wheel drive. This Yukon package includes matching front and rear gears so both axles can be upgraded together.
