    Jeeps are off-roading beasts. They muscle through extreme conditions and are the ultimate transport for crossing rivers, cresting wilderness ridges and climbing near vertical angles. If you acquired a vintage Jeep from Craig’s list, the classifieds or the local salvage yard, chances are it needs some work. Identifying the T-case for replacement can be tough for novice and enthusiasts alike. Once it’s identified, there may be Dana 20 rebuild kits to replace what you’ve got, providing more power.

    Identifying the Model
    The Dana Model 20, released in 1962, is one of the most respected T-cases around, whether it’s street bound or trail roving. It was called the “silent-type” as its centered rear output housing enabled efficient direct drive, 2-wheel drive. Most markings begin with “C18”, so make sure you don’t mistake this for the larger Dana 18 case or the single speed, automatic only Model 21.

    Built to Last
    The Dana 20 transfer case is cast iron, which makes it nearly indestructible. It’s one of the strongest of all transfer cases. It’s light, compact and capable. Replacing worn or factory parts with high-quality aftermarket components can give it new life, delivering its original power.

    Fit Your Vehicle
    Some parts may be universal, but many Dana 20 transfer case parts such as the manual trans output shaft gear are proprietary and can be used with only this T-case. Use the Dana 20 transfer case diagram to ensure components match. Other parts such as the TJ Wrangler Transfer Case Yoke may be used with a couple of different cases.

    At 4WD.com, we know you’d rather be behind the wheel than in the garage. Use our vehicle tool to make sure the part you order is the part that fits your make and model. Place your order today and our six warehouse locations and vast inventory ensure you get the parts you need to get you back on the trail, fast.
