Gear Splitter

I have a 1976 3/4 4x4, just wondering if there is a gear splitter out there that dosnt cost a fortune. I have the NP435 tranny. Can I get one that will bolt to the back of the tranny? There is quit a bit of space between the trans and the Case. Thanks for the help.

Howdy Cat! good luck finding one less than $1300. The ranger gear splitter is about the best option i've seen but it bolts in front of the tranny. Gear vendors makes one that goes behind the tranny but it is electric and more costly. This topic has been discussed before on this board, I recently asked about this too. Use the search and try to find more info. Have fun! -David

how about a overdrive 5 speed? the newer trucks come with a overdrive 5 speed and with a divorced transfercase this could be a good possibillity you would have to check input shaft and throwout bearing and bellhousing compatibility maybe fabricate a crossmember and have a new intermediate shaft made

I have Gear Vendors installed on my '79 Supercab. It was put on by the previous owner in California.

The truck has a C-6. The truck cannot be used in 4 wheel drive with the system on. It gives the trans. 1st, 1 1/2, 2nd, 2 1/2, 3rd, and overdrive. So essentially I now have a 6 speed trans with the system on. I love it. Not cheap though.

The gear vendors unit is awesome. It can be mounted either behind the tranny or behind the transfer case. If mounted behind the tranny you can use it in 4WD as well. If mounted behind the transfer case it can only be used in 2WD.

On my '79 the unit is mounted to the back of the t-case and will only operate in 2 wheel drive. Maybe it's differant for trucks with a divorced t-case.

I agree it is awesome. From highway driving to cruising around town it's totally differant than the stock shifting of the C6. Much smoother and OD on the highway.

From there sight:

GEAR VENDORS makes specific adaptation kits for each model of transfer case. This is far more costly than other manufacturers who will have you move your transfer case because GM/Dodge/Ford all use the same patterns between the transfer case and transmission (thus one kit fits all). Simple for them but a host of engineering problems for you and the truck. By making specific extension housings to each model/brand transfer case GEAR VENDORS is able to have a better engineered product with great engineering benefit to the final installation. Fact is, when you are in 4X4 there is very little desire to use GearSplitting and overdrive, it's 2wd where these benefits are needed. All our kits bolt directly to the rear of the transfer case and are electronically locked out during 4X4 operation.

Good point, I was refering to a divorced transfer case with a 4spd set up.

Which I don't have. It would actually work out well in an area with long, cold, slippery winters. Somewhere you stay in 4x4 for a whole season.

I haven't looked real good but I don't even see them listing anything for a truck older than a '82. Probably would have to give them a call.

This is easy to do with a 4x4. Do you know what kind of transfer case you have already (i.e. NP203 or NP205?) and is it married to the tranny or seperated by a driveshaft? You can use a 203/205 doubler which joins the range box from a 203 t-case to the front of an NP205. This gives you the option to split your 2:1 ratio down to 4:1. The kits can be had for as little as $500. All you need is that box from the 203 and a good 205 and you're in business. They are designed to work with the married cases but I think you can use them with divorced units IF you have a range box from a divorced 205.
