Dana 30 Reverse Cut Ring and Pinion

Dana 30 reverse cut ring and pinion gears deliver enhanced strength and efficiency for Jeep front axles running bigger tires or demanding trails. The Dana 30 reverse cut (high pinion) front axle — most commonly found in the front of 1984–2001 Jeep Cherokee XJ, 1987–1995 Jeep Wrangler YJ, early 1997–2006 Jeep Wrangler TJ (before the low pinion transition in some later models), and select 1993–1998 Jeep Grand Cherokee ZJ — positions the pinion above centerline with reverse cut gears for superior load handling, reduced driveshaft angles under compression, and better overall durability in lifted or aggressive off-road setups.

Popular ratios such as 4.10, 4.56, 4.88, and 5.13 compensate for 33–35" tires, restoring low-end torque, improving crawl ratios on rocks or steep inclines, and preventing engine strain. Premium sets from trusted brands fit the high pinion Dana 30 precisely (typically 27-spline pinion), but require matching master install kits (bearings, shims, seals, crush sleeve) for correct setup, backlash, and pattern to avoid premature wear.

Pairing new gears with upgraded axle shafts, heavy-duty U-joints, or differential reinforcements helps the Dana 30 withstand increased torque and abuse reliably. Whether you're correcting sluggish performance after a tire swap on an XJ, optimizing a YJ for trail performance, or building a classic TJ for serious wheeling, browse our Dana 30 reverse cut ring and pinion sets to find the ratio and quality that suits your Jeep.

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