Parts for the

Dana Model 20 Transfer Case

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

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.

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.

Dana 20 front output rear bearing billet cap upgrade

Seal up and shim you front output shaft rear bearing from the inside with this innovative bearing cap assembly. The anodized cap, shims and o-ring sealed bolts are included.

Many parts are available for the Dana 20, including gears, shafts, 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.
