Vehicle Fitment

• 1984–1990 Jeep Cherokee (XJ) (2‑Door/4‑Door, 4.0L I6 and 2.5L I4, RWD/4WD)
• 1987–1995 Jeep Wrangler (YJ) (2‑Door, 2.5L I4 / 4.0L I6, 4WD)

Fitment Notes

• Specifically for vehicles equipped with Dana 30 front axle (reverse rotation) and AMC/Model 35 rear axle. 
• 4.88 gear ratio — if your vehicle currently runs a different ratio (for example 3.54 or 3.07) you may need to change carriers or other components. 
• Trim levels and special editions (e.g., Sahara, Renegade) included as long as axle configuration matches; trimming needed if axle type differs.
• Does **not** fit beyond 1995 under verified sources. Confirm axle and gear ratio before purchase.

Features

• Includes front and rear ring & pinion gear sets — all in one kit for a full regear job.
• Master overhaul kits included for front and rear axles — bearings, seals, shims, hardware to support installation. 
• High‑performance heat‑treated gear sets designed for durability under off‑road and heavy use conditions. 
• Optimised for 4.88 final drive ratio — improves low‑end torque, towing capacity, and larger tire compatibility. 
• Ring & pinion set engineered by Yukon Gear & Axle, known for precision manufacturing in the gear industry. 
• Lifetime Y.E.S. protection plan offered by manufacturer (for as long as you own the vehicle) — provides confidence in purchase. 
• Comprehensive kit means fewer separate purchases — simplifies installation and ensures matched components. 
• Ideal for off‑road, rock crawling, or larger tire builds where stock gears are insufficient and higher ratio is desired.

Product Description

The Yukon Gear & Axle YGK002 kit is a full re‑gear solution designed specifically for select Jeep XJ and YJ models equipped with the Dana 30 front and Model 35 rear axles. With its 4.88:1 final drive ratio, this kit significantly boosts low‑end performance, making it an ideal choice for off‑road enthusiasts, large‑tire builds, or vehicles used for towing and heavy duty applications.

Each kit combines front and rear matched ring & pinion gear sets along with complete overhaul hardware — bearings, seals, shims and installation components — ensuring the job is streamlined and the components are well matched for optimal gear mesh, noise reduction and long‑term durability. Yukon’s use of advanced heat‑treating and precision manufacturing techniques provides a robust platform worthy of high‑stress use.

When installing, you must ensure that your vehicle’s axle configuration matches: a Dana 30 front axle (reverse rotation) and an AMC/Model 35 rear axle, and that the existing gear ratio is compatible (you cannot simply drop in 4.88 gears if you currently have a non‑compatible carrier without modifications). If you’re upgrading tire size, need stronger gearing, or want an all‑in‑one kit for reliability and quality, this YGK002 kit from Yukon is a top choice.
