Overdrive for a Deuce???

[JimTheScot989]

OK, so I have a mind which wanders aimlessly once in a while. But, has anybody successfully installed an add-on overdrive onto a Deuce to get highway transport speeds, like 65 mph?? I've seen Waterloo's xmission mods. I'm asking about an add-on in the drive train.

Bigger tires seems like the best bang for the buck. I doubt the engine makes enough excess horsepower to warrant a proper overdrive unit.

Yes.... I have but it would probably cost more to make a prototype with machining and molds then what a fleet of deuces cost. Then after that.... You will probably have to sell 1000 units to get close to being on track financially again. I figured if I wanted more speed and comfort. It would be cheaper to buy brand new luxury 4X4.

With my 395's I am cruising on the highway at 60 and can push 63-64......and that is running almost straight wmo.......I would agree that the bigger tires are the way to go....sometimes power just isn't there to keep it above 60 if you have head wind or much of an incline.

Just my thoughts but I could carefully consider the effects of modifying a deuce to run at that speed.

Thank you guys for your considerations. I thought about modifying the Deuce (which includes larger diameter tires) but that permanently puts the vehicle into that HP / speed/ power range, which permanently alters its off-road & heavy characteristics, basically making it a weak runner of its former self. Same with the transmission mod. So I'm looking for the "add-in" OD which used to be popular in the 60's. Anybody remember them?

Use the search function. This has been discussed many times.

I think Gear Vendors still has one for RVs that would do what you want.

Worth the expense and hassle? Not to me.

To each their own, but nobody here has gone down this road after doing the research IIRC.

Yeah, a brownie box. Called that cause they were made by Brown-lipe. They don't work with out a LOT of work, and the ones I know that were installed, lost the 6x6 feature. The link I provided is THE ONLY option that does not have any downfall, other than being a steep 5th. BUT you are wanting an add-on ratio, which will have the same issues as a taller 5th.

As said, its been done, feel free to look for it.

Hooray for tailwinds!

Some day when one of the world's billionaires comes to his or her senses and adopts me, the first thing I'll do is commission a six-speed Deuce transmission. The stock ratios are fine. All we need is one more gear after fifth.

this is simply not true. there is NO downside to the trans mod that i am aware of. it only changes the now somewhat useless 5th into what is in effect a real od. less money than tires and wheels, easy to install.

I have the the OD in my M108 and love it...

 

[Heath_h49008]

Even just for the longevity benefits, the Waterloo OD kit is worth it.

Well, just considering its weight; if that isn't positive feedback... what is????
