Gear Vendors Overdrive
Hey guys, I bought a new gear vendors overdrive for my 96 dually. I was just wondering if any of yall have one and what your opinions of them were. I can't wait to have a double overdrive.

i had the US gear on my 89 its basically the same thing, i liked it especially with the manual transmission. it was nice having that inbetween gear running the hills so you can keep it right in the sweet spot of the power. double over was nice on the flat stuff but with a head wind or any climb the egts come up in a hurry. If i wasnt gonna get a bigger truck to tow my trailer i would put one in my F250, but im looking at a medium duty like a international 4400 to do it.

nev,
It works great, my mileage went from 420 a fill up to over 500 when I'm not pulling. Probably something like 17 or 18 from 14mpg. I love it. The install kinda sucked because I had to fab some of my own stuff. When it comes to single cabs, gear vendors doesn't have a clue. Extended cab or crew cab you could have it bolted in in an hour. They sent me a few different brackets, and none worked. Not to mention I have my exhaust running up through the middle of the bed for my stacks. That was tricky. But I made it all work. But I had to wrap my exhaust in header wrap double thick to keep from overheating the gear unit. All in all not to bad.
Kwik,
Your right kinda.....You can use it engine braking. But not below 30ish mph. The gear unit works off hydrolic pressure. The od won't engage until the driveshaft is spinning fast enough which is about 30 mph. So you can't split first and second. I tried to split 3rd going up a hill and it shuttered like it didn't have enough pressure. So I split 4th, and 5th. But if your pulling massive shizzle then no you don't want to use it to slow down. It will do it, it just has it's limit. So far with a gooseneck and a 8000 lb truck no problem. When I'm pulling that heavy I only use 4th over. Because going forward 4th with the od unit on is stronger than your stock 5th gear. And yeah the guys at gear vendors said you shouldn't back really heavy loads on soft ground. The way I figure, if I gotta back my rig up in the mud fully loaded, I screwed up somewhere and should pay the price of having to figure out how to get out of there without backing up. But forward, it's bullet proof. Not to mention, I ain't gonna split reverse no way. I quit smoking crack years ago LOL! But over all, no problems with it as long as you know it's limits. Just like every thing in life though right? And I would HIGHLY recomend this gear unit to anyone interested.

Why do the EGT's increase when in double over?
