Full Master Rebuilt Transfer Case


Our Dana 18 is professionally and meticulously rebuilt. We use the best components, including bearings, bushings, seals and gaskets built by our Dana 18 specialist and expert. Any available updates and improvements are performed.


Because of the many variations involved and shipping cost variations, we encourage you to contact us directly by phone or e-mail. We will help you put together your transfer case to best fit your requirements.  If purchasing online, choose the "Contact me with a shipping quote cost" shipping option.



Transfer cases are built to order and take 1-6 weeks to ship. Contact us for current build times.





Your transfer case package is palleted, wrapped, fully insured and ready to bolt into your application. Novak will seek the best competitive shipping rates with our extensive trucking networks. It will arrive at a location of your choosing, though we strongly recommend a business location with a dock / forklift for delivery, as residential and liftgate fees can add up to an extra $100. per delivery.

All transmissions and transfer cases are built to order. Average lead times vary from days to weeks depending on the time of year. Please call our salesmen at 877-602-1500 for current lead times.


Parts for the

Dana Model 18 Transfer Case

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.

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.

There are three kits available; one for each of the three major generations of the Model 18. Our exclusive intermediate shafts are made at Novak from a triple-alloy gear steel and case-hardened to exceptional hardness and are the strongest and hardest shafts available. They also feature o-ring grooves at both ends, assuring a better seal than factory; extra o-rings are also included.


All kits include all the bearings, seals, gaskets, shims, small parts, intermediate shaft, and comprehensive rebuild guide.


For Early Generation Versions


For Mid Generation Versions

For Late Generation Versions

Applications & Compatibility

This kit fits all Jeep Dana 18 Transfer cases and most IH Dana 18 transfer cases.

For 1-1/4" Versions


Dana 18 Billet Bottom Cover Pan

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 grey for further protection. A shallow version is also available as a stock upgrade.

Included are the stainless socket head button cap screws, drain plug and sealing washer. Read the review at 4x4review.com


Dana 18 PTO Port Cover  

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.


Dana 18 Gaskets & Seals Set

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.

Installation Requirements

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.
