everything is completely symmetric in the rear with the 4 link wrt lateral loads. Lots of benefits. Probably really good on the trails to wrt flex. What diameter is the antirock rear sway bar? Did you have oem bar, what diameter was that? I don’t have the oem rear bar.

Yeah I am intrigued by this. Still wondering about the loads in the rear. 🤷‍♂️ I don’t think I have the stones to add this just yet or the time to play with it on the the trails. But I sure would love to beat on some other rig that has this setup to test it out. 😂

of course. Just trying to add to the conversation, but more likely rambling and confusing. 😂 I don’t like the cost or exhaust requirements. I am going to add the belltech or oem rear bar and probably the antirock front bar.

having a rear anti sway bar will add torsional rigidity to the rear. Left/right articulation is resisted by the torsional resistance from the anti sway bar. Uncoupling the sway bar (manual or electronic) removes the torsional rigidity and obviously increases articulation. articulation...

yeah I feel for the Ford engineers. It is easy to trash talk them but I am sure they are up against a crap ton of external safety constraints.

Not sure about what is exactly meant by steering angle. I am just learning the nuances of automotive engineering and terminology. Please add context if available. The linear motion of the steering rack, via the tie rod ends, is translated into rotational motion of the wheel. Since the wheel is...

Agreed. Ford may simply have some external constraints wrt rack programming. 🤷‍♂️ Based on kinematics, the front wheels are forced to rotate about the king pin axis. Axis defined by UCA and LCA wheel knuckle attachment points. The intersection of the king pin axis with the road surface plane...

Heavy 13.5” wide 37s have a much greater affect on MPG than a gear oil viscosity change in the rear diff. Yet most don’t question that.

Yeah I lived thru all of that. I must add that the data you got back then was usually pretty solid. 90% of everything out there nowadays is total crap. Way to easy just to make shit up now.

Good info right here. Thanks. When details are flushed out please compile in first post. I have been contemplating this also. I think with a light and skinnier 37 the OEM rear end will be fine if you don’t beat on it. At least for my use case. I have a 22 non SAS and it has mounting locations...

Very curious how the 4 link rear and walker shocks on the front anti sway bar is gonna ride on the road. Keep rockin on. 👊

@tobyw Did your front springs settle a little?

I wish I had some decent welding skills.

I appreciate the video on the FDU swap and the attention to details. Thanks for the effort. I am eventually going to tackle this job on the floor with jack stands. nice to clearly see the pita I am in for. Definitely going to do the steering rack at the same time. The guys on this thread...

Curious about this 4 link rear. how to keep the rotational forces at bay (Moments generated by offset of CG and roll center). ? Also reaction forces that are now carried by the links? And forces at frame mounts? Looks like the upper links are bent to accommodate the oem frame mounts but then...

that is not how engineering research and development should be conducted. That is merely inserting a product prematurely into a complex system and hoping for the best with random testing that doesn’t even adequately quantify testing and/or design variables. What variables are controlled during...

The gearing has been discussed quite a bit but the increased loading gets somewhat overlooked. No way I just add bolt on portals without addressing the loads.

many folks are just not very knowledgeable and easily influenced. Anyone with some basic knowledge will question things and easily see thru him. The tie rod brace is the perfect example.

Just saw this thread. Definitely worth the read. 🤣 Late to the party and would love to join in on the bashing. Anyone with some basic knowledge can easily see the guy buries himself every time he opens his mouth or poorly articulates something in writing. sad thing is, I fear much of the public...

I seem to recall that you have the rear OEM sway bar, the front antirock sway bar, rear track bar relocation, 6100 bilsteins (ford performance variant), and 33s. I was wondering if you had any additional thoughts on the suspension handling after some more time driving around? I am thinking of...
