As our vehicles become more and more capable rigs, and after developing areas such as suspension, lockers and tires, we find our vehicles lacking in one area: Control and Gearing. The lower your gears are, the more control you will have over your vehicle. With proper low gearing wou will be able to ‘crawl’ your vehicle over obstacles that you previously viewed as impossible! This is where our Dual Transfer Case kit comes into play. Our Adaptor kit allows you to mate the reduction box portion of a NP203 transfer case to the stout NP205. The addition of the NP203 range box gives the option to run either transfer case independently in high or low (1:1, 2:1) or to run both in low (2:1 x 2:1) and DOUBLE your reduction for an astounding 4:1 low! Our kit mates factory NP203 and NP205 transfer cases, giving a wide array of vehicle application compatibility, not to mention the all-gear combination is capable of handling big block power! We offer everything from our base kit, to everything including rebuilt transfer cases. Read on, you’ll come to find that the NorthWest FabWorks kit is far more than just average... 
- NP203 Adaptor Plate - Center Index Ring and breather - NP205 or D300 Adaptor - 8620 Billet Intermediate Shaft - PTO Cover with fill Plug - Mounting and Clocking Hardware - CR Seal & O-Rings - Fiber Gaskets What Else Do I Need? On top of our basic kit you will need: - 1 NP203 to mate to your transmission - 1 NP205 with either a short 32 spline or 31 spline input gear, or a Dana 300. - A 2nd crossmember or custom crossmember - A means to shift each transfer case from high to low range. - Modify your driveshafts to fit new driveline length. Are There Different Versions Of Each Transfer Case? Our Adaptor kit is compatible with a "Figure 8" NP205 that has either a TH400 short 32 spline input (from the factory), or a 31 spline ford input (Swapped in) installed. "Figure 8" Style NP205's are found the GM and Dodge vehicles. This will require an input swap and boring of the case if your current NP205 is a 10, 23 or 27 male spline version, as the 31 and 32 spline female inputs use a larger input bearing. GM and Ford 6 Bolt Round NP205 Our Adaptor kit is compatible with the 6 bolt round pattern GM and Ford NP205 transfer cases. The GM round pattern case was found in 1985 and newer GM applications. These GM cases require an input gear swap to the short style input gear, but does not require the case to be bored out. All married ford cases are short female 31 spline input with this 6 bolt round pattern. We have drilled both the Ford and GM patterns onto one adaptor plate. Jeep Dana 300 Our Adaptor kit is compatible with the Jeep Dana 300 with the 6 bolt round pattern front face. The Dana 300 can be used with 23 spline female input gears, or aftermarket 32 spline input gears. The 32 spline input version may require work to be done on the 32 spline NP203 output shaft. Our adaptor kit allows you to mount the D300 in passenger or drivers drop configuartion, however be prepared for custom fabrication if you run your D300 in a flipped configuration. Figure 8 Kit 6 Bolt Round Kit Dana 300 Kit 
______________________________________________________________________ Our Adaptor kits can bolt ANY combination of Ford GM or Dodge NP203/NP205 or Dana 300 together. There is NO upcharge for a weird combination at all! Since our adaptors bolt together, if you require changing a transfer case in the future (ie. change your NP203 from ford to GM type) you do not need a whole new adaptor, you only need to replace 1 of the adaptor plates, its a minimal cost in comparison! Blind Tapped Clocking Holes & O-Ring Seals: The bolts that hold our adaptor together are what is called "blind tapped" meaning the holes do not go all the way through the adaptor plates, and thus no leak points. The center index ring of our adaptor kit is sealed on both surfaces with a large O-ring, also eliminating any leak points. Clocking Bolts Externally Mounted: The bolts for Center Index ring are mounted outboard, and can be easily reached with a wrench. You do not need to completely disasemble the adaptor to change clocking locations. Precision Manufacturing Our Adaptors are 100% CNC machined out of 6061-T6 Aluminum. They are NOT welded together, and as such are always perfectly parallel. The bolt patterns on all of our adaptors are extremly accurate, and as such we run tight tolerances on all our parts. Billet PTO Cover 
We now include a billet PTO cover with fill plug for your NP203 Range Box. These covers are anodized for lasting looks and etched with the NWF Logo. These covers are not welded - therefore always 100% flat. Only the best from NorthWest Fab. Completeness: We offer everything you need, and we don’t cut corners. You’ll find everything you need right down to cut gaskets, breather fittings and all the hardware nessesary for your installation. Mounting: The NP203 adaptor plates is drilled and tapped to 1/2"NC at the base for easy mounting, the spacing matches a factory NP203 foot orintation. This allows the use of a 2nd crossmember to properly support the combo. Billet Mainshaft: .jpg)
Our Kit includes an 8620 Billet mainshaft to connect your NP203 to the NP205 or D300. These shafts are heat treated 8620 gear steel; they are super strong and super tough and made in the USA. We do NOT respline factory shafts. With our kit you can drop the clutch in confidence! **Our Billet Mainshafts are availible separately for $299.00USD Tapped Adaptor Holes: Our adaptor is tapped on the NP203 adaptor plate. This means you do NOT need one wrench on the bolt head and one on the nut. You simply tighten the bolts through the NP203 range box directly into the adaptor. Its all in the details. Finally, And Certainly Not Least, CLOCKABILITY The NorthWest FabWorks Dual Transfer case is the most versatile adaptor for sale today, nobody even comes close to offering the options that our adaptor kit does. First things first – What on earth is “clocking”? Clocking is the ability to mount (usually a transfer case in the 4x4 world) at different rotated position. Rotating a transfer case up or down from the factory location has its advantages as well as downsides: Clocking your transfer case up is often done as it easily increases ground clearance under your transfer case. However it will also create steeper driveline angles on your front driveshaft. Steeper driveline angles require expensive driveshafts to run at the required angle. Clocking your transfer case down is sometimes necessary on vehicles with a large amount of lift. This is done to flatten driveline angles; however this is at the cost of ground clearance under your transfer case. Although some of our competitors can offer their adaptors in a clocked position (usually at an upcharge!) or allow you to weld an adaptor into a fixed position, none offer a truly versatile clockable and re-clockable adaptor. Our adaptor allows our customers to mount their transfer cases in various positions to find what works best for THEM. At any point you can disasemble the adaptor, change the rotation, and try the new position in your rig. 
Your first positioning choice is for your NP203 Range box. You Have 3 Options: Option 1) You can mount your NP203 in the factory vertical position. This makes for the least amount of custom fabrication, as well is more compatible with factory adaptors. Option 2) You can mount your NP203 upside down from the stock position. This rotation will increase ground clearance, however a portion of the range box will enter the cab of the vehicle. Only a few factory adaptors will allow this rotation to take place, and shifting the unit is slightly more complex. Option 3) You can mount your NP203 90* to the right or left, (dependant on which side your rear transfer case has its front output on). Ideally you want the shifters to be located on the top of the range box, to avoid any potential leaks through the shifter. Slightly less floor modifications are nessesary over the inverted setup. Again, most factory adaptors will not work, and will require custom fabrication. Your 2nd set of clocking options is for your 2nd transfer case, either a NP205 or Dana 300. There are many options: The Center Index Ring allows your NP205 or Dana 300 to be clocked 4" up or down in 1" increments, aswell as left in stock location. Meaning you can move you NP205 1", 2", 3" or 4" up or down, to find whatever fits YOUR needs best! Nobody else can even come close to giving you these options. Not to mention you can change your clocking position whenever you like! It does not matter if you have a passenger or drivers side drop transfer case, you will still be able to clock your transfer case in the same manner. Click Here For 203/205 Installation Guide
