doubler ??

[Jason4x4]

Is it possible to use a 203 t-case with the 203 range box?

yes, but why? get a np-205. there is more adpt. out there and they alot more stonger. my 203/205 doubler has never failed me yet.

the reason I ask is that I already have a rebuilt 203 in my truck, and I have another one for the range box in my garage. What would be involved?

Uhh, you would break the second '203

Seriously, I doubt the chain in the complete box would handle the new (doubled) torque input, even if new, especially under any serious wheeling.

To use an ORD doubler, the second case would have to be a TH400-style with 32-spline input.

NWF's setup requires a 31- or 32-spline input.

After you drop several hundred bucks to a grand on the adapter proper, plus several hundred more for a triple stick kit, new mounts and driveshafts, and whatever else, another coupla hundred for a '205 is well worth it . Otherwise you have a polished turd

It could be possible but not if it's in a blazer as the thing would be way too long and you would have very little rear driveshaft. It would also require a special intermediate shaft to be custom made with a male spline to mate into the female input shaft of the full 203 t-case.

A rebuilt 203 would easily sell for the cost of a 205 so you could then pick up a 203/205 doubler. As mentioned above using the 203/203 combo your chain isn't going to last all that long.

I'd hate to see you spend all the money on custom adaptors etc, just to have it grenade after a couple of days on the trail.

I was thinking the input of the '203 -- presuming it was a TH400-style -- would be identical a TH400-style '205, so the same adapter/intermediate shaft would work.

The logic being -- never having seen a TH400/203 combo and trying to stay that way -- that if they both bolt up to a TH400, they should be the same, right?

Anyway, it's all academic, as a 203/203 would suck, but I'm thinking out of my butt

Thanks for the replies, I was driving home last night and was thinking about it. I will definatly stick with a 205.
