Parts for the
Dana Model 20 Transfer Case
The Jeep & IH Dana Spicer 20 is one of the most respected transfer cases on the trail and street. Professional level rebuild work is possible for the conscientious shadetree rebuilder.
We offer nearly all parts at the component level, and our master rebuild kit, which includes the most thorough collection of parts offered anywhere.
The Master Kit
Our master rebuild kit has been assembled for our customer's rebuilds as well as our own. It is the most complete kit we've seen anywhere and features all the consumable and wear item components.
It is very common for our customers to do top-level rebuild work, using good methods and by following our included instruction guide.
We suggest the rebuilder have access to a set of snap ring pliers, and a small arbor press, in addition to standard shop tools. The full rebuild procedure is covered here.
Essentially all parts for the Dana 20, including gears, shafts, etc. are available new and affordably so. Our parts ordering module is provided below. For anything not shown, contact us.

In addition to this, its deeper pocket increases the fluid capacity of the Dana transfer case by about 16 oz., increasing the life of the components within.
The pan is made of corrosion resistant 6061 aluminum and then anodized in clear zinc for further protection.
Included are the stainless socket head button cap screws, drain plug and sealing washer.
