Rockwells and 4 Wheel Steering Build

For the record I blame JCF for this. Had she not shown me Area BFE and the rigs that run there I would not have decided to do this.

I have been looking for axles and talking about building a four wheel steer rig for a while. I have almost bought a few but the deals never worked out. After many texts and a few phone calls to another member that Builds them Big I was introduced to Red River Parts in Texas.
Red River Parts & Equipment, Inc.
I bought two 2.5 Rockwells both front steering axles for $1938 shipped to me. The truck arrives tomorrow and then the fun starts. Stacy's Civic gets moved out of the garage and the Rocks get a new home. I need some more jack stands and will weld up some with wheels to move them around better. Rocks are not light.

I will start with stripping them down and replacing the drum brakes with pinion brakes, replace all bearings and seals, install lockers F/R.
I have spent a great deal of time on Pirate researching other Rockwell builds. WF is great but not many of us are running Rocks. So if you are thinking of doing this here is some light reading.
Link's to rockwell question's and info... - Pirate4x4.Com

Part, parts and more parts. Many people have them these are a few.

Red Barn Customs, 2.5 Ton Rockwell Axles, Mud Boggers, CNC Plasma Cut, Yale Mich
- ROCKWELL PARTS
Patooyee's Parts
ROCKWELL PRODUCTS

I will be making my own link tabs and towers. But the Top hat from Mudpro looks very easy. Might buy that one.

As for the rest of the build I am thinking YJ frame and tub, CJ front, Atlas II and an undetermined motor and tranny. Coil overs and 4 link F/R and 49" IROKS

Another helpful Pirate thread.

New Version of my 4-link Analyzer & Request for Help - Pirate4x4.Com

Some things I will NOT be doing. I will not be discussing my 4 link calculations at ALL. I do not want to even get started with that discussion.
I will not be done any time soon. This project will be a time lapse.


I will be posting plenty of pictures. Hopfull the first will be tomorrow.

Get some good chemical stripper for when the housings are ready slap it on and let it sit, save the wire wheels for the crap that won't come off. That olive drab is a @%$!%. I built a ranger on rockwells a few years ago here's a few more sites. Much respect on this one I know what's involved keep us updated!
Ouverson engineering (if your running over 500 hp)
Ballistic fabrication (for your brackets)
Boyce equipment
Eastern surplus

Links not working.


I won't be over 500hp. This is going to be a four seater family rig not a KOH rig.

I will most likely fab the brackets myself except I really like the Mudpro Works Top Hat. I am an engineer and use Solidworks every day. I will model my frame and axles and all brackets. I am really looking forward to using the 4 link calculator with the 3D software to see the flex before I weld.

Sounds like a cool project. Subscribed.

How about a cummins for the engine? Not really sure how you drive or the type of wheeling you do but I feel like that would be a good engine for a family-oriented rig.

When I do my next rig it will be wishbones front and rear with airshocks I like the wishbone better than the 4bar stuff as its easier to get right the first time, tougher, and way way less joints to buy.

You paid less than a dollar/pound for Rockwells. Well played!

This will be fun.

I am going to 3D model everything in SolidWorks. I will even plug the 4 link calculations into SolidWorks to calculate Roll Center, Roll Axis, COG etc.

The ME's at work are chomping at the bit to start. I will make pdf drawings available to anyone interested.

I was happy to see that they were not covered in grease and grime.

I am thinking of blasting them before I take them home. I was planning on replacing all the boots, seal and bearings. One of the guys at work thinks this is a bad idea. Any thoughts?

Also thinking of using the drums as the base for jackstands.

Wonder why he doesnt think you should? I dont think that stuff is expensive and I would definately consider it if they were mine. Yeah the drums would be good stand bases, my super tall ones use 16.5 wheels as bases.

He thinks the grit will be to difficult to get out and get behind seals etc. I am replacing all the bearings, seals and boots. I am more concerned about rust. If I blast them now I will have to lay a coat of primer on to keep them from rusting while I work on them. Then I will have to sand off the primer when I weld.

I was planning on 49" IROKS but I found a place that sells the Michelin XML 395/85R20 for $695 for a set of four.
395/85R20 46" Michelin XML tires

The big downside to these tires is that they tip the scales at 220lbs each.

Ive heard poor, poor things with those michelins, youll need to groove the hell out of them, they are like 8 ply sidewall so they dont flex well and ride like a train wheel.

And just axles and tires your rig will weigh more than TJ lol.

Oh and btw, I hope to the offroad gods you are posting this on pirate or even JF. Much better help, and tech than here at WF.

You make me want to sell the axles im building, and buy two 14 bolts and shave em and cut em down

I have read all the bad things about the Michelin's too. The price and the fact that this rig will not be driven on road has me considering them. The weight is ridiculous though.

I am only posting here because this is really nothing new for Pirate. Pirate is where I get nearly all my schooling.

But its still appropriate there for some good questions you may need!

Id reckon 30% of people here don't know what rock's are lol.

But they wont be bad for offroad, heavy, and i dont think they grip too well. But then again, all hearsay.

Don't worry I get all my questions answered on Pirate. I just don't think they need another ho hum Rockwell build. Just like WF doesn't need another Wave thread.
