      Features, Description, Reviews, Q&A, Specs & Installation


      • Fits Front Dana 30 Axles
      • 4.88:1 Ratio
      • Requires a 3.92 Carrier or Numerically Higher
      • 26 Spline Count
      • 1 Year Warranty
      • Fits 1997 - 2006 TJ Wranglers

      Gear Specs. Designed to match front Dana 30 axles, this Yukon Gear gear set is installed by off-roaders who want to run larger than stock wheels for stronger torque, without the loss of power entailed in too low a gear ratio. These tough Yukon gears greatly improve off-road performance even in very rough terrain or under suboptimal conditions. The 26 spline count enables smooth meshing with stock axles if desired, and the final gear ratio is 4.88:1. Upgrading to a 3.92 or numerically higher carrier is must if you want to install these gears. Yukon offers a 1 year warranty.

      Application. This gear set fits 1997 - 2006 TJ Wranglers with the Dana 30 short pinion front axle.

        Listen up Lifted Jeep owners

        After I lifted my TJ 6" and threw on 37's, I loved the look of it but dramatically felt the power difference. There are a bunch of myths on forums of upgrading a muffler or other bogus, but this is the only solution to regain original performance. Have a mechanic install because there is extreme precision required. Make sure to run the same ratio on front and rear axles, because if you don't and just happen to turn on 4WD, you will hear a crack and your wallet will be surrendered.

      I am re-gearing my 2000 Sport to help run 35s over my stock 31s. When re-gearing, is this all I need or are there additional parts I need?

      • The Yukon Gear Dana 30 Ring Gear and Pinion Kit will include the front ring and pinion hears only, you will still need shims, a gasket and pinion seal, and marking compound, as well as the same parts and gears for the rear diff.
