Gear Splitter for NV4500

Does any one know if it possible to put a gear splitter off of a medium duty truck on too the nv4500. Basically what I am looking for is an overdrive gear splitter but I'm not sure if it is even possible to do. I tried searching for some threads on it but it seems that know one has brought this topic up. If anyone has any alternate options that they like better than the gear splitter or if you have any idea about which one would be a good for the nv4500 please let me know.
thank you,
Grady

Gear Vendor makes a Underdrive to Direct set and a Direct to Overdrive set. I looked into them for a while, but then found out that they are rated to "only" 700 ft/lb of torque input. If you stay mostly stock you'll be ok, but I'm already far out of that range on the output.

Most likely the ONLY way you could use a MD unit,would be to divorce mount the t-case. Have short shafts run between the trans and t-case. All it takes is money.

don't forget about US gear.

edit: and, i think you can downshift and utilize engine braking w/ the US gear unit. i have heard that you cannot on the gearvendor unit.

I can see the need for a extra gear box if you are going to stay with a some what stock engine, but couldn't you just add a turbo, injectors and do a little pump work and end up with the same drivability, more power and easyer to drive? If you are set on this you could allways look into a 6 speed or a fuller 7, or 10.

I don't think he's going for more power. Besides even if he was, a overdrive wouldn't add any. I'm guessing he wants another gear for better mileage and a splitter for towing with less drop in RPM at shifts.

Ya thats exactly what i was going for, I do a ton of highway driving because i commute for school everyday and im around 2100 rpm at 70 and if i could drop that down I'd be happy. Also i live in the city with a bunch of hills and sometimes my gears really get hindered by the hills. Ya it does seem like it's more trouble than its worth, my friend ran the idea by me and I wasnt sure if it was possible. Gear Vendor does seem like a good bet but my truck is rated for about 750 ft/lbs and I dont think i would want to risk that about of torque on it. I really appreciate yalls imput. I really thought the one manufactured by US gear would be the best bet. Have any of you hear of anyone pulling one from a medium duty truck in a junk yard?

More torque and RPM would solve the problem. If it is a stock truck and you want to stay as close to stock as possible, just add a 3K GSK or a 4K GSK that way it does not stop adding full fuel until 2700 or 3600. The 4K gsk will require 60 lbs springs on at least the exhaust. The Governor Spring Kit will make you fell the difference, and shift gears less. A GSK will not make you change a clutch or change the drive line.

To get more torque you will need a new clutch soon and to get it you can slide the fuel plate change the DV's and holder then get larger injectors, DV's and Holders are optional.

If it was me and I did not feel like getting more power I would add the RPM with a GSK if you install it yourself it will cost 150 dollars or less and take a afternoon, taking you time and reading the instructions. Also add a little timing say to 14.5 degrees it will help.
