Ford ½ Ton TTB to ¾ Ton 8-Lug conversion
For those that are interested.
Before we attempted this, there wasn’t a whole lot of info out there other than it can be done with Chevy stuff. ½ ton TTB cannot be converted to 8 lug using ford parts, at least not anyway that I’m aware of.
This is a quick overview of the parts required to convert a ½ ton TTB setup to an 8 lug ¾ ton setup.
After replacing the rear axle with a ford/sterling 10.25 in the ’94 Bronco, the front needed to match bolt patterns so we would only need to carry one spare tire. After lots of research and a few calculations as to cost, utilizing as many stock components as possible was best.
Sure some may argue that a SAS was a better option, but seeing we already had most of the donor parts laying around for the TTB conversion, it would be way to expensive to SAS it. We already had a dead F-250 heavy duty 4x4 donor laying around, that’s where most of the parts came from.
F-250 parts truck $500
misc front service parts $200
GM 10 bolt 8 lug axle used $100
Total cost of both axle swaps together was ~$800-900
Here are the parts required:
¾ Ton 8-Lug conversion parts list
1982-1996 Ford Bronco/ F-150 4WD
Front Axle Parts
Ford ball joints, inner axle shafts, knuckle U joints, drive shaft, and steering knuckles are stock components for a 1994 Ford Bronco without 4WABS.
TTB third member is a Dana 50 from a ’93 F-250 Heavy Duty
8 lug parts are from a 1988 ¾ ton Chevy Suburban, listed below:
The ford spindle studs need to be replaced with the longer Chevy ones.
This truck was converted back in March and has had about 5K miles put on the current setup so far with no problems reported to date.
The only pics I have are of the final result and they kinda suck, I wish I would have taken some during the initial build, but didn’t.
It’s pretty straight forward and could be easily accomplished in a day or two if you have all the parts already.

do you know exactly what calipers you used?
like jb5 or jb7?
I ask cause I got some from autozone, and traded in the old ones as cores, and the hoses don't look like then can even fit up to the calipers
