The Jeep & IH Dana Spicer 20 is still one of the most respected transfer cases on the trail. Professional level repair, assembly and upgrade work is possible for the conscientious shade tree builder.

In addition to our master rebuild kits, we offer nearly all parts at the component level, as well as several upgrade part options.

These kits fit all Jeep Dana 20 Transfer cases and most IH Dana 20 transfer cases.

The Master Rebuild 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. This kit includes:

20MR

Right Stuff Gasket Maker Valvoline 80W-90 GL-5 Gear Oil, 1 qt 2 qt fill Dana 20 billet front output bearing cap

This kit includes:

World class bearings
Novak's premium hardened intermediate shaft with sealing o-rings
Premium bearings (deep ball, tapered rollers, races, needles)
High-grade seals
Shim pack
Shift springs
Poppet balls
Premium gaskets (including rubberized cork pan gasket)
O-rings (+ spares)
Shift rail thimble covers
Poppet plugs
Expansion plugs
Yoke nuts & washers
Intermediate shaft retainer plate
Novak's comprehensive rebuild guide
Customer access to Novak's experienced Dana transfer case experts

Our exclusive intermediate shafts are made at Novak from an alloy gear steel and case-hardened to exceptional hardness and have o-ring grooves at both ends, assuring a better seal than factory; extra o-rings are also included.

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.

The Intermediate Shaft Kits

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.

Valvoline 80W-90 GL-5 Gear Oil, 1 qt 2 qt fill

Dana 20 Billet Bottom Cover Pan

This extended capacity, anodized billet aluminum bottom pan solves a few Dana transfer case dilemmas:

Thick, machined mating flange replaces the dimpled, warped sheet metal original
Drip free sealing surface with the use of RTV or RTV + gasket
Increased fluid capacity by 16 oz
Adds rigidity to the structure of the transfer case
Superior heat shedding

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

Dana 20 Gaskets & Seals Set

There's not a better gaskets and seals kit available. The pan gasket itself (otherwise the most prone to leaking) is cut from a rubber-cork compound.

Turn Key, Fully Rebuilt Transfer Case

Our Dana 20 is professionally and meticulously rebuilt. We use the best components, including bearings, bushings, seals and gaskets built by our Dana 20 specialists and experts. All known updates and improvements are performed. Put the experience of thousands of Dana transfer case rebuilds to work for your Jeep.

Because of the variations involved and shipping options available, we encourage you to contact us directly by phone or e-mail. We will help you put together the transfer case which best fits your requirements.

Note that we can supply a core Dana 20 or we can arrange to have yours sent in with a core credit of $400. Transfer cases are built to order and typically take 1-3 weeks to ship. Contact us for current build times. Costs range from $1,667. to $1,795. depending on your configuration, shifters, etc.

Logistics

your transfer case package is palleted and wrapped (if trucking is required) or packaged in a double-wall box (if by parcel), 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 (if trucking), as residential and liftgate fees can add up to an extra $100. per delivery.
