Dana 30 Standard Cut Ring and Pinion

Dana 30 standard cut ring and pinion gears bring back lost torque and improve off-road capability when fitting larger tires to classic Jeep front axles. The Dana 30 standard cut (low pinion/standard rotation) front axle — most commonly found in the front of 1974–1983 Jeep CJ-5 and CJ-7, 1984–1986 CJ-7 and CJ-8 Scrambler, early 1987–1995 Jeep Wrangler YJ (select configurations), and some Jeep Wagoneer or Comanche models — uses conventional low pinion placement with standard cut gears, delivering a lightweight, proven design that's easy to source parts for and widely used in vintage restorations.

Typical upgrade ratios such as 4.10, 4.56, 4.88, and 5.13 offset the gearing loss from 33–35" tires, regaining low-speed grunt, enhancing crawl on rocks or steep climbs, and reducing engine strain during highway driving. Quality gear sets fit the Dana 30 low pinion precisely (usually 27-spline pinion), but proper setup demands a master install kit (bearings, shims, seals, crush sleeve) to dial in backlash, preload, and pattern for quiet, long-lasting operation.

Pairing fresh gears with upgraded axle shafts, heavy-duty U-joints, or differential covers helps the Dana 30 withstand added torque and trail abuse reliably. Whether you're re-gearing a classic CJ for better trail performance, correcting sluggishness in a YJ after a tire upgrade, or building a vintage Jeep for modern capability, browse our Dana 30 standard cut ring and pinion sets to select the ratio and quality that matches your project.

Dana 30 standard cut ring and pinion gears are available in 3.08, 3.54, 3.73, 3.90, 4.10, 4.11, 4.56, 4.88, and 5.38 ratios.
