CK5 - The Full-Size GM Off Road Community

We are now taking orders on our new Billet NP203/205/D300 kit's.

The adaptor is comprised of four main pieces, the Reduction box (203), Center indexing ring, and final T case (205, D300 etc) and billet 8620 shaft. All of which (shaft excluded) are 6061-T6 aluminum.
Each mating part was mapped out using digital equipment, the fit and accuracy is excellent.

The design allows the customer to mount each transfer case at whichever desired location they want (and able to change it at any time).


The NP203 Reduction box can be mounted at stock, 90* left/right, or inverted.

The NP205/D300 can remain in factory location, or be clocked (at the front output) 1, 2 or 3" up or down from stock. There are other rotations possible (205 front output below the input, or 1 2 or 3" left right from this location) that are less common. The combinations are nearly endless, and should suit any need. These combinations are atcheived with ONE adaptor. You don't need a different adaptor for different rotations.

This allows you to get the product, and try various combinations to find what works best for YOU. Every rig is different.

Also, if you wanted to change either transfer case (from a D300 to a 205, ford to a chev etc) at a later date having already purchased an adaptor you only need to change ONE part of the adaptor, the cost is minimal. The center index ring will mate any combination.

The photos shown above are the prototype version.
Some new added features:
All clocking ring mounting holes are blind tapped holes, and accessible from the outside of the adaptor. This means ZERO leaks through the clocking holes.

-All unused clocking holes, both drilled thru and tapped are filled and supported with steel plugs.

-The NP205 and NP203 plates seal against the clocking ring using large o-rings, for ease of dis/re-assembly. You don't end up with an RTV mess.

-The Intermediate shaft support bearing is fully encompassed in the NP203 plate.

The introductory price for the kit is $699Usd + Freight. This includes:
8620 billet mainshaft, All necessary hardware, gaskets and seals.

Lead time on the adaptor is only a few weeks for a chev version, with the ford and D300 versions to follow.
We also carry the accessories such as yokes, u joints, everything right up to rebuilt T cases. Some more info is availible on our website www.NorthWestFab.com (http://www.northwestfab.com/)

PM me for shipping quotes. :waytogo:

can't wait for mine to show!:D

very nice! you plan on making other types of adapters? I was thinking more of a klune-205 doubler? :) them boys over at klune want an arm and a leg for adapters tho. :mad:

j

Can you list the transfer cases that will work with this?


For example, I have a 203 that was mounted to a t350, and a 205 that was mounted to a t350. What would I need to install the doubler?

I would need the pattern (and rotation) of the klune, along with the face-to-face measurment, and which 205 pattern you want to mate to. I can do it, one-off parts can somtimes be expensive. What are they asking for the intermediate adaptor?

Currently you need a Big bore case with either a 31 or 32 spline (short) input gear. I've got competitive prices on the input gears (new) I also have Factory 31 spline input gears I can cut a great deal on.

You will need to bore your case if you have a 27 spline version. If you need to know how to take your case apart, I can walk you through it. Boring the case should be $40-50 at your local machine shop.

We also have rebuilt TH400 version NP205's starting at $399. Shipping on a complete case is usually around $100.

So the Ford version isn't ready yet? Or will it just be a week or so longer than the Chevy one? I need to take a look at finances but may be contacting you very soon.

Ford's arn't far behind the chev's, maybe a week or two. I had pre-orders for the chevs first, so they get done first. Otherwise its all good, I've got the ford 8620 shafts here in stock.

Any good news for us 10 spline 465 freaks? :D

how about prices on full kits, IE: rebuilt transfer cases, all put together and with shifters?

awsome, will it come out of the box and be able to bolt up to a 700r4?

or mabye a 4L80E?

Bolting up to a 700-R4 requires nothing more than a factory TH350 adaptor and a spacer between the transmission and NP203. I've got TH350 adaptors in stock, and I can probably source the spacer.

4L80E will require drilling and tapping of the face of the 203 range box. Fairly easy task, simply index the 203 range box onto the splines of the 4L80E, rotate it to where you want it orintated, clamp it, and drill it. Easy trick if you don't have a set of transfer punches is to use a drill bit of the same OD as the adaptor hole to allow it to pilot to center, then drill to the correct tap drill size for 3/8NC.


*edit* Whoops. Wrong log-in. Can't find the delete button either...:confused:

awsome, the saving has begun
god i got to much crap to get:D

what kind of space do you need when using the TH350 adapter? I was planning on a new output shaft for my 700R4 and drilling and tapping the 203 to the 208/241 pattern.

In factory form, the TH350 adaptor is very short. once you add the required spacer, I beleive your approx the same as a 700R-4 and a factory NP208 adaptor. Use the NP208 adaptor and re-drill, you don't need an aftermarket tailshaft.

If you go the AA tailshaft route with the factory 1.1" thick TH350 adaptor, you have the shortest combo possible. This can potentially lead to driveshaft and pan clearance problems. This combo is about 3.5" shorter than the factory NP208 adaptor, albeit probably the most cost indusive.

If you currently have a 700-R4 and NP208 adaptor....I'd leave the tailshaft be, redrill the face of your 203 and call it golden.

haha just reread the pirate post, nvm

8620 Billet Anyone?
32 Chev on the left, Ford Center, and D300 on the right. :saweet:

me me me!:woot:

want to touch the shaft... hm never thought I'd say that.

Do you have 32 spline inputs for a 203 available for sale? How much?

Have you thought about producing either a 32 spline input for the 203 or a 27 spline output for an SM465 (32spline) so clutchmen have the ability to use an SM465 with a TH350 input 203?

Harley

do you sell rebuild kits of a 205 if so how much?

Yes we do sell 205 rebuild kits

They go for $169us

We have 32 spline inputs availible for the 203 brand new, I won't be able to confirm a price for you until monday.

27 and short 32 spline 465's are in the works to offer more options to the 4 speed crew. We have so much "in the works" its ridiculous. Need it? We either have it, or will make it.

Any good news for us 10 spline 465 freaks? :D

10 spline 465/ 203/ 205 setup!
Equivalent to the 1st Gen ORD thing that they figure no-one wants anymore... (they are wrong!)

Good to see a Canadian version coming out. And at a competitive price!

Just let me keep my 10 spline 465! :)

Updated photos on first page! :D

(prices assumed chev cases)
For a rebuilt NP203 range box (assembled to the adaptor), NP205 (th400 version), and adaptor it is $1327 plus freight charges. This includes a $50 credit when purchasing an adaptor and T case at once.


I have a 465/203 (yep,the rare 465/203) in my truck now- 10 spline. If I were to order the entire kit as quoted above, what would I need to bolt it to my 465? And what would it cost above and beyone the $1327?

right now I have a 700R4 with a 2" spacer mated to a figure-8 205 via a TH350-to-np205 adapter. I have a spare 203 range box laying around... is there an easy way to get from where I'm at now to a doubler?

Jethro,

The $1327 quote is with a rebuilt 203 rangebox, if you already have a 203 to mate to your transmission, then we can subtract thathe cost of a rebuilt NP203 rangebox from your total.

If you need a Adaptor and 205, The costs are as follows:

Adaptor $699.00

NP205 $449.00 (TH400 version chev NP205)
I can offer a Chevrolet case with a Ford 31 spline input for $399.00. Might as well save $50, one spline won't make a strength difference.

32 spline front output for the NP205 - We offer these @ 79.00 when installed in a rebuild case and HIGHLY recommend the swap. LOTS more yoke options and a strength increase aswell.

We offer $50.00 credit when purchasing an adaptor and NP205 together.

Twin stick rail mod for the 205? It is $59.00, this is a personal preference option.

If you already have the rare SM465/203 combo, you would need:

Adaptor: 699.00
NP205 399.00 - 587.00 Depending on options chosen.
Freight is usually $120ish depending on your Zip
It'll range from about $1220 to $1406 depending how pimp your 205 is.

We've also got 1410 and 1350 yokes for your 32 spline 205 :D

Take off your NP205 adaptor, and put a factory TH350 adaptor and range box right on the end of the spacer and everything will bolt up nicley. We have TH350 range boxes and adaptors in stock if you'd like a fresh unit.

The AA shaft will work if you want to save 2" of driveline, but if you have the spacer, I really wouldnt bother even a K5 has the driveline to work unless your lifted sky-high.

actually, i think i have a 350-to-203 adapter laying around somewhere. Its the really thin one right? like an inch thick maybe?

nah, about 5-6" is all Im ever gonna lift, I have 5" and 39.5s right now. fenders be damned. ;)

Im gonna have to seriously think about this. I was pondering a Klune-V... but I have the 203 and 205 and the adapters/spacer already. Might have to go doubler... maybe get a 1410 yoke for my ff14b at the same time. I live in WA, if I road tripped it maybe I could save some shipping $$$?

Yup, the TH350 adaptor is about 1" thick. I wouldn't be surprised if you had one, they're very common.

If the 205 you have right now isn't a female input gear we're offring free ford NP205 input gears with the purchase of a 203/205 adaptor to convert your current 205. If you already have a TH400 or ford type case, then we will ship your adaptor to you for free. :D

If you've never done any NP205 work, you can bring your case to our shop and get it freshened up with a rebuild and we will install the new input and show you how to do NP205 service work for the future.

It's a bit of a trek, since we're on Vancouver island you have to get the ferry from Angelas to Victoria, or from Vancouver to Nanaimo. I'm not sure how well the drive from WA to the island will fit into the ferry schedules.
You're always welcome to swing by whenever you like for a visit.

We've got 1410 yokes for NP205, D60 and 14FF on the shelf. Thats what I run in my K5.

Cheers,

-Kyle

damn, forgot about the 205 input part. Yeah, mines definitely not the th400 version, so I'll prolly need a new one. A furd one would be fine, I won't miss the 1 spline. ;) I have messed with my 205 a little bit, I swapped in the ford 32 spline front output myself, and didn't screw that up. I also have the relatively well done write up they did in Petersens a while back. I could prolly figure it out. Is there a rebuild kit for just the reduction portion of the 203? Also, will I need to modify my current 205 any to use that furd 31 spline input? sorry for all the annoying questions. I was always planning on going Klune... ;) :grin:

j

This may be a stupid question, but are your prices in Canadian or American dollars?

Although we are in Canada, we sell 90% of our products to the USA, and thus we list in american dollars to make everything easier on the majority of our customers.

:thumb:

Currently have 6 kits on the shelf...going fast :grin:

Do you have complete rebuild kits for the NP208 also?? Chain included??
-Randy

We Sure Do :D

Currently 15 kits on the shelf, going fast!

well i got to try my doubler out over the weekend and man did this thing work great. Perfect fit,shifters work good and it crawled up just about everything i pointed it at. Anybody thats thinking of this as part of there build up dont worry about the parts or quaility because its all there. They give you everything you need in the kit to do the job..

The hardest part is the big snap ring on the main shaft. till i got the right tool.

Thanks again to Kyle and Jordan for the quiality parts and the service after the fact.

Thanks everyone for the awsome year.

Do you offer a shifter boot for your triple stick?--Eric

I am interested in your kit. I currently have a th350-205, both factory in my 71 blazer, and will be picking up a th400-203 this weekend. What is needed to do a doubler?
