Dana 44 HD Ring and Pinion

Dana 44 HD ring and pinion gears deliver extra strength for demanding applications in vehicles that tow heavy loads or see off-road abuse. The Dana 44 HD (heavy-duty variant) — most commonly found as the rear axle in 1993–2004 Jeep Grand Cherokee (ZJ and WJ models, especially towing packages), with some older Dodge and International truck applications from the 1950s–1970s — features an 8.5" ring gear diameter, 29-spline pinion, 10 ring gear bolts, and thicker components for increased torque capacity compared to standard Dana 44 axles.

Available ratios such as 3.54, 3.73, 4.10, and 4.56 allow for tire size compensation, improved acceleration, or better crawl on trails when upgrading from stock gearing. Quality aftermarket sets from brands like Dana Spicer OE, Revolution Gear, USA Standard, Motive Gear, or Yukon fit the Dana 44 HD precisely but require a master install kit (bearings, shims, seals, crush sleeve) for proper backlash, preload, and pattern to ensure quiet operation and longevity.

Pairing these gears with upgraded axle shafts, heavy-duty bearings, or differential covers helps the Dana 44 HD handle increased power, larger tires, or towing stress reliably. Whether you're re-gearing a Grand Cherokee for better towing performance, strengthening an older truck setup, or building a durable rear axle, browse our Dana 44 HD ring and pinion sets to find the ratio and quality that matches your needs.

Dana 44 HD rear ring and pinion gears are available in ratios: 3.08, 3.54, 3.73, and 3.90.
