Dana 30 Short Pinion Axle Parts

Dana 30 short pinion ring and pinion gears, axles, traction devices and more. The Dana 30 short pinion (also called low pinion or short reverse pinion) variation was used in 1997-2006 Wrangler TJ (all non-Rubicon), late 2000-2001 Cherokee XJ, mid-1996-1998 Grand Cherokee ZJ (some), and certain other applications, featuring a shorter pinion shaft design (1.376" diameter, 26 splines), 7.2" ring gear, (10) 3/8"-24 ring gear bolts, 10-bolt cover, and carrier break at 3.55/3.73 (3.55 & lower on one carrier, 3.73 & higher on another). This low-pinion setup (standard cut gears) is distinct from high-pinion/reverse cut versions in earlier XJ/YJ or JK models, with common factory ratios of 3.07, 3.55, 3.73, 4.10, and 4.56—aftermarket options extend to 4.88, 5.13, or 5.38+ for larger tires (31-35"+) and improved crawl/torque, though the short pinion can limit some gear choices and requires specific install kits for proper preload/backlash. Popular upgrades include regearing to match rear ratios after lifts/tire upsizing, stronger chromoly shafts for off-road abuse, fresh bearings/seals rebuilds, or traction devices (lockers like OX, Eaton Truetrac, or Spartan) to enhance grip—while the design offers good strength for mild to moderate builds but often sees swaps to Dana 44 for extreme use. Browse a wide variety of high-quality Dana 30 short pinion components, including precision bearings, heavy-duty shafts, ring and pinion gear sets in available ratios from trusted brands, traction devices like lockers, and installation kits, to help you rebuild, regear, or strengthen your TJ/XJ/ZJ Dana 30 for dependable trail performance and longevity.
