Dana 44 TJ Rubicon Rear Ring and Pinion

Dana 44 TJ Rubicon rear ring and pinion gears are essential upgrades to restore power and improve trail performance when running larger tires on your Jeep Wrangler. The Dana 44 rear axle — standard on 2003–2006 Jeep Wrangler TJ Rubicon models (all trims) — uses standard cut/low pinion gears with an 8.5" ring gear diameter, 24-spline pinion, 10 ring gear bolts (mixed 7/16" and 1/2" pattern), and 30-spline axleshafts for enhanced strength and durability in off-road conditions compared to non-Rubicon TJ models (which use Dana 35 rear).

Common upgrade ratios such as 4.11 (stock-like), 4.56, 4.88, 5.13, and 5.38 compensate for 33–37" tires, regaining low-end torque, boosting acceleration on steep inclines, and maintaining crawl efficiency. High-quality aftermarket sets from brands like Revolution Gear, Yukon Gear, Nitro Gear, Motive Gear, or USA Standard fit the TJ Rubicon Dana 44 rear precisely but require a master install kit (bearings, shims, seals, crush sleeve) for accurate backlash, preload, and contact pattern to ensure quiet, long-lasting performance.

Pairing these gears with upgraded axle shafts, heavy-duty bearings, or differential covers helps the Dana 44 handle increased torque and abuse reliably. Whether you're re-gearing your TJ Rubicon for better rock crawling after a tire upgrade, optimizing for trail duty, or building a capable off-road rig, browse our Dana 44 TJ Rubicon rear ring and pinion sets to find the ratio and quality that matches your setup.

Dana 44 Wrangler TJ Rubicon ring and pinion gears are available in ratios: 4.11, 4.56, 4.88, and 5.13.
