Hi Guys,

I'm new in the Bronco world. I came across a cheap 71 that was heavily modified as a mud truck, and I want to make it more street-friendly, but still keep it as a very strong off-road vehicle. I spoke with the guys at Pirate 4x4 and I have a list for a game plan, and they recommend me to join this forum for more bits of advice. Have any you guys seen or worked on this Bronco?

Interesting suspension set up. Somebody put some time into it. How does it feel on the road as is?

It feels, loose, wild, slow and unsafe. ahahaha

I want to cut it all out, change the 39s to 35s and bring it down. And eventually, put a small block to bring the radiator back in.

Turn the exhaust out the side, the rear is a low pressure zone and will pull the fumes inside.

How the exhaust is set up now makes sense for a mud drag truck, but not for on the street.

I like the look of it. Its a mauler! I would try to work the suspension a bit to get it to handle the road better. Drive it for a while then add more power later. Very unique and built for business. Have fun with it.

Just read your thread on Pirate. Guys gave you spot on advice. It wouldn't take too much to fix that rear suspension. That's where I would start. And remove the front coil spacers asap. If you need rear shackles hit Migs up. He's a vendor on this site and makes a bad ass set.
If you do have F150 axles there are offset coil towers to fix the lean of the front coils. Pretty sure Duff's has them. You might be money ahead pulling the axles out and buying a set from someone that did a 1ton swap or something. Bolt right up.

Lift blocks on the front springs in my book big No no. I would get rid of those. And most bronco the leaf sprigs are on top of the axle not sure why they were put under the axle

Funny with all of that work it is still uncut. With 2 inches before you hit the rear fenders
Fun project

I will redo the rear and front suspension.

I wonder why the 39” tires are not all cut up as it is right now. Is it possible for the springs to be so hard that it doesn’t flex enough to rub?

I'd second the advice that's been offered already...take time to think about what you want to improve to start off with...suspension/handling would seem to be the highest priority for street handling (and you certainly seem to be on point in this regard)....lots of stuff that has popped up on here and other 4wd forums, in terms of "well intended and ill-executed" suspension work. Start from scratch here, get it handling well...it's a bit less overwhelming and a lot less of a financial impact to start with something that you can slowly work away at, while still having a functional Bronco....mine was bought and still is in 1000+ pieces!

Hey Tunderchief, welcome! And wow, what a Bronco!
But as has already been said and you already knew, it's certainly way off from being set up for the street.
I hope you got a reasonable deal on it too, because you'll be spending time and money for awhile. But then, that can be the fun part! (well, the spending time anyway. Not sure about the spending money yet).
Only worried about the money for how frustrated you might get when working on it. Not that the money you spent would not have been worth it. But just the beginning...

Sounds like you know your way around a wrench and are not afraid of tackling this, so you're ahead of the game already if that's the case.
I would say yes to the stiff comment. If it has spent any time at all bouncing in the mud, then much more flex in the suspension and the body would be thrashed already.
One possibility is that those tires were not on it for the fun, but another is that it has as yet not spent any time off-roading after the build was finished.
So don't take anything for granted yet or you may be doing more body work than planned.

At this point too, you should look at your time and costs for things like spring hangers and perches, radius arm mounts, etc. and then look around for an old frame that someone is getting rid of and see if it's not a better way to go.
At that point, VIN matching is the only thing you have to concern yourself with. Worth a little looking around anyway. Old frames in good condition would probably have been $200 a couple of years ago. Maybe still less than $1000 though?
Just thinking out loud anyway. Good luck no matter which path you take!

And enjoy that cool rig when you're done. I kind of like the pickup styling.
But can understand too why it's so sketchy to drive at this point.

Thank you,

Although I'm leaning toward putting 35s on it to make street-friendly and lowering it, I'm still debating if 37 would be worth it and if I take it easy until axle upgrade. Below is a list of things I collect in a forum at Pirate4x4 and talking with some people. Let me know what you think.

Rear suspension:
• Remove all the tractor links and cut off all the mounts that were welded on for them.
• Cut all the spring hangers off the frame and weld in some factory mounts, or aftermarket mounts in the factory location.
• Return to the factory-style shackle, remove revolver shackles and spring over the axle.
• Replace the rear axle with a full width to match the front axle???

Front suspension:
• Change coils and remove the spacers/lower coil buckets,
• Remove drop bracket for the steering stabilizer and the track bar drop.
• Bring track bar and drag link on the steering closer to parallel as possible.
• Replace the current track bar with a straight link???
• Upgrade the radius arm drop brackets to aftermarket long arms.

Welcome to Classic and congrats on picking up a solid looking 71.
You definitely have your work cut out for you but sounds like your on the right path. The front and rear suspension, axels, and brackets would definitely be the first thing to tackle.

I took a long look at it all and this is the situation.

For me to redo the rear closer to stock, I will need to cut the fender and put wheel wells to fit the 35s. To do that I need to move the radiator, and to move the radiator, I need to swap the engine.

The reason the 39s don’t rub is that the spring and link don’t let it flex that far to touch the fenders. Also, as the axle is on top, the gas tank is not much farther than the fender is from the tires. So if the tire rubs on the fender, it prevents the tank from being hit. It does run like something between and an old truck and a tractor.

Those tires have been there for a few years, so there must be something in the 3.5 gear axles to hold the 39s. Whoever put the time, money and engineering to make this Bronconstein, did something that is holding the 39x18.5 tires. It has semi float and all disk, so there was work done the axles. I did some research and it looks like something between a home-made rock and or mud racer. Until I swap engine and move radiator, I may put the 36 or 37 and redo the front a bit, I feel its higher than the rear anyway.

There’s something crass, hard and cool that I love about this truck. My idea has always been to have a cleanout Mad Max-like Bronco.

Also, I put a 35 on it to check and it looks a bit small for the lift, maybe because I'm used to the 39s. I found some 36x12.5 tires, but I'm not discarding the 37s idea yet, I don't know when I will be able to swap the engine and only then properly redo the suspension after it. I’m also concerned that as it is if 35s flexes far enough, it may hit the tank before the fender.

What’s a way to make this homemade 4-link set up be any better without having to swap to small block first?

How could make it somewhat ok until I swap engines?

Thoughts?

Hard for anyone to say from "way out here" really. I'd have to see it in person to make any reasonably accurate and sensible suggestions.
For starters that does look like a huge gas tank. You should take some measurements and we can compare them to known tanks that don't reside in the same space as the rear differential.
Most are made to clear even though they're larger than stock. The typical 23gallon tank will not be hit by the axle in most cases.

The spring-under-axle setup was for stability, but also to LOWER it (yep, lower it) from all the other modifications. The lift is achieved by not only the highly arched springs, but also the extreme spring hangers at each end of the leaf pack.
If you were to swap the axle back to under the springs for example, you'd probably lift it another 7" or so. That's the thickness of the axle tube, plus the thickness of the spring pack, plus the spacing of 2 spring perches. The one you're removing and the one that you're adding to the top of the axle housing where the originals used to be.

To then lower it that same amount (or more) you would remove the front hanger and replace it with something resembling stock. Same for the rear shackle hanger and shorter, stock shackle. You can see pictures of the stock setup hereabouts on any of the build threads where a bare frame is showing.
Then you'd still have to change out the tank for something that clears.

You're right to worry about the tire sizes and the body though. It's currently sitting as a purpose-built machine with no suspension compliance in order to save the stock body. If you make the changes back to a more stock-ish setup (as if!), with perhaps 5.5" of suspension lift, you'd still need to cut the rear fenders because most of the tire sizes you are looking at, along with the new wheels that you are needing to fit them, will be too wide to fit under the fenders when the suspension is moving. Way too wide probably.

But then you might lose much of the Mad Max look you were liking.
It's a tough one for sure. You're pretty much taking a purpose built vehicle and making another purpose built vehicle out of it. Either way it's a lot of dealing with the good, the bad and the ugly of a highly modified Bronco.
