Dana Axle Fitment Guide: How to Find the Right Spicer Part

Dana Spicer OEM parts are application-specific. The same component — a U-joint, an axle shaft, a ball joint, a pinion seal — comes in different part numbers depending on your exact axle model and configuration. Ordering the wrong part number means waiting twice. This guide helps you identify exactly what your application requires before you order.

Step 1 — Identify Your Dana Axle Model

Most Dana axles have an identification tag or casting stamp on the differential housing that identifies the axle model. If the tag is missing or illegible, your axle can also be identified by vehicle year, make, model, and trim. Common Dana axle applications by vehicle:

Dana 30

Light-duty solid front axle. Found in Jeep Wrangler TJ (1997–2006), Jeep Wrangler YJ (1987–1995), Jeep XJ Cherokee (1984–2001), Jeep MJ Comanche (1986–1992), Ford Bronco, and GM S-10 Blazer. The Dana 30 is also used as a rear axle in some early Jeep CJ applications.

Dana 35

Light-duty solid rear axle. Standard rear axle in Jeep Wrangler YJ (1987–1995) and Jeep Wrangler TJ (1997–2006 base models), and Jeep XJ Cherokee (1984–2001). Identified by its smaller 7.5-inch ring gear diameter.

Dana 44

Medium-duty solid front or rear axle. One of the most versatile Dana axles ever produced. Front applications: Jeep Wrangler TJ Rubicon (2003–2006), Jeep JK Wrangler Rubicon, Ford Super Duty (some years), Dodge Ram 2500 (front). Rear applications: Jeep Wrangler TJ Rubicon, Dodge Ram 2500 (rear), GM 2500 trucks (some years).

Dana 50

Medium-heavy solid front axle. Found in Ford F-250 and F-350 Super Duty trucks from approximately 1998–2004 with front leaf spring suspension. The Dana 50 uses a unique outer stub shaft design — part numbers are not interchangeable with Dana 60 front components.

Dana 60

Heavy-duty solid front or rear axle. The benchmark one-ton truck axle. Front applications: Ford F-250/F-350/F-450 Super Duty (2005+), Dodge Ram 2500/3500 (front). Rear applications: Ford F-250/F-350/F-450, Dodge Ram 2500/3500, GM Silverado/Sierra 2500HD/3500HD. Identified by its larger 9.75-inch ring gear.

Dana 70

Heavy-duty rear axle. Found in Ford F-350/F-450, Dodge Ram 3500, and GM 3500HD trucks. Used primarily in single rear wheel heavy-duty applications requiring greater load capacity than the Dana 60.

Dana 80

Maximum-duty rear axle. The largest production Dana axle. Found in Ford F-350/F-450/F-550 Super Duty and Dodge Ram 3500 with dual rear wheel configurations. Features a 10.5-inch ring gear and is designed for maximum payload and fifth-wheel towing applications.

Step 2 — Confirm Front or Rear Application

Many Dana axle models are used in both front and rear positions, but with different part numbers for each position. A Dana 60 front axle shaft is not the same as a Dana 60 rear axle shaft — confirm your application before searching by part type.

Step 3 — Find Your Part Number

Once you know your axle model and application position, navigate to the relevant collection — U-Joints, Axle Shafts, Ball Joints, Seals, etc. — and filter by your Dana series to narrow results. If you have an old part in hand, the Dana Spicer part number is typically stamped on the component or printed on the original packaging — use that number to search directly.

Step 4 — Verify Before You Order

OEM part numbers are the most reliable fitment reference. Cross-check your part number against your vehicle's confirmed axle designation if you have any doubt. A five-minute confirmation call saves a week of waiting for a return and reorder.
