gear vendors....anyone use them?

[wide body]

i've read alot on here about how to "hot rod" these trucks and how great the mileage gets after putting a "tuner" on them. but i haven't read anything yet about using something like a gear vendors setup. does anyone on here use them? i've read a few articles where differen super duty owners have put them on their trucks and how great they worked. one of them was an f450 or f550 that had an increase in mileage from 8 something to 11 something. the truck weighed in at around 12,000lbs from what i remember. if you were to couple GV setup with an H&S/spartan tuner we'd be getting better mileage than a prius

From what I understand about the GV overdrive unit, they can't handle to torque these trucks make (even in stock form), and also can't handle to load of towing. No first hand experince, just what I've heard/ read about them.

i don't have any first hand experience with them either. i also have not talked to anyone personally that has used their products....BUT, from what i've read about them, they are designed to help with towing, improving mileage and longevity of the motor by lowering the RPM at highway speeds. i went through their site yesterday and there is a number of wrightups on different PSD combinations using them. i was just curious if anyone on here has used them and what their opinions were of them. they are NOT cheap though. most kits seem to be in the $3000 range. OUCH! but they claim that trucks with a gear ration of 4.10s or higher tend to see a 20% increase in fuel mileage

The US gear one is much better uses and electric solinoid instead of hydraulics. Meaning you can use it in reverse and in 4wd. GV does not offer this. I know the Us gear one can hold 2,000 ft-lbs, so its plenty strong.

Uhhh, scratch that last, I did a google search and it looks like they went out of business.

I wanted to get a GV for my F550 with 4.88's but they said it wouldn't last. Apparently it has a 25k lb max rating and if you try to tow for extended time at anywhere near that combined weight they said it'll overheat and fail. I tow one specific customers boat back and forth from southern New England down to Key West every year, it goes over the scales at 23k combined, and the guy at GV said I'd be pushing my luck even with that.

I heard good things about the US Gear unit but I guess they are out of business? I'd love to find something like US Gear unit that would work. Anybody know of any other options available?

I think that your only bet is to find a good used one.... good luck!

thank you for the input! that's exactly what i was looking for. i don't see a point in adding something to these trucks that would limit what they can do. especially at the price of a GV system

thanx again
