The Stovebolt Site Forums The Shop Area Driveline What ring and pinion will work in my 46 3 qtr ton

I want to go faster , I need something in the 355 range

3:55 is what I put in my 46 1/2 ton.

Tim, not sure what would work best in a 3/4 ton. For the 1/2 ton guys the 3.55 is what most recommend. Perhaps an entire rear end change would be best for you money wise unless you're pulling a heavy load on the farm.

Hi Tim -- Welcome to our site! I'm going to move this to the driveline forum as I think you'll get a lot of specific help there.

Thanks for stopping by!

Not sure what fits in that 46 3/4 ton rear. Another option would be an overdrive trans like a T-5 and TALL tires.
Best of luck.
PS, I used a late 60s 3/4 ton 4:11 ratio in my 53 but not sure if it works for your year.

There isn't much you can do with a 3/4 ton rear. I think an OD transmission would be a good approach. However, your bolt pattern is going to be different than the 1948 and later which eliminates most OD transmissions that will bolt right in. Clark made a 5 speed OD that fit the old style clutch housings. It was a popular conversion 50 years ago, but the old Clarks are pretty rare these days. Most of them have been scrapped. Years ago, a friend of mine bought a Borg Warner OD from me that was for a Y-Block Ford and he made it fit, but I don't remember what all he had to do.

From what I can tell in the factory service manual, you have a full floating axle. I'm assuming it's the same as the later HO52's. In that case, you'll have the 4.57 gearset and the best you'll be able to come up with is a 4.11 set from the 68-72 trucks.

4.11 are getting hard to find, and you don't gain as whole lot. However, if you get faster gears, won't have enough HP to break the wind.

I think I have the 4.11 set that I took out. Send me pm if you want them.
