The Jeep & IH Dana Spicer 18 is still one of the most respected transfer cases on the trail. Professional level rebuild work is possible for the conscientious shade tree 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.
For Early Generation Versions
For Mid Generation Versions
For Late Generation Versions
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.
There are three kits available; one for each of the three major generations of the Model 18. Our exclusive intermediate shafts are made here from case-hardened triple-alloy and are the strongest available.
All kits include all the bearings, seals, gaskets, shims, small parts, intermediate shaft, and comprehensive rebuild guide.
This kit fits all Jeep Dana 18 Transfer cases and most IH Dana 18 transfer cases.
These kits are a reduced version of our Master Kits. They contain the specially hardened intermediate shaft, O-rings, thrust washers, bearings and snap ring.
For 3/4" Versions
For 1-1/8" Versions

This extended capacity, billet bottom pan is the answer to a few Dana transfer case dilemmas. Its rigid construction replaces the thin, warped factory pans virtually assuring a drip-free seal and adds rigidity to the transfer case. Extended depth increases fluid capacity of the Dana transfer case by about 16 oz. extending the life of components within. The pan is made of corrosion resistant 6061 aluminum and then anodized clear for further protection.
Included are the stainless socket head button cap screws, drain plug and sealing washer. Read the review at 4x4review.com
Sometimes utility and eye-candy can cross over. But, go ahead and get it muddy if you'd like. After seeing the difficulty of finding Dana 18 PTO covers, we added this one to our line-up. It's made from 3/16" thick aluminum (great for heat dissipation), media tumbled and anodized black. We follow up with a little engraving. Because of its rigidity, it will seal better than factory PTO cover.
There's not a better gaskets and seals kit available. This one makes it possible to have a Dana 18 and a drip-free garage floor. The pan gasket itself (usually the most problematic) is cut from a rubber-cork compound.
Essentially all parts for the Dana 18, including gears, shafts, etc. are available new and affordably so. Our parts ordering module is provided below.

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.
