4 link axles.
 

I have driven and owned both Chevelles and 5.0 Mustangs with thier versions of the tri angulated 4 links.

But there are kits to mount the upper bars next to the pumpkin to accomplish the same thing.

How do these handle or act in comparison. Since they move the upper bars further apart?

what about a '98 and up P71 rear axle. It is a 4 link with a watts link mounted on the front of pumpkin. It was also designed for high offset wheels, so the suspension mounts are clear of the axle ends and bearings are well outboard.

that last generation crown vic represents the pinnacle of full size rear axle suspension design

Re: 4 link axles.
 

The axle your reffering too I think is the 2003 amd later.

That axle is practically wider then the car I got. It barely fits under a F100 or C10 with modern rims.

The 4 link portion would require cutting the floor for room, and nessitate frame mods to accommodate the width. With the watts link likely being quite easy.

The 2002 and earlier would be a good choice to cut down with 9" ends to start the project. As I can add perches to the axle and use the leaf spring mounts as the lower links

Re: 4 link axles.
 

From your other threads on tire sizes and engine choice, combined with this one on 4 link I thought this was going to be an extensive build so axle shortening would not be out of the question.

Assuming this thread is about your '54 sedan....
Any 4 link into a '54 frame will require a lot of work, the frames are a hat cross section box of relatively thin material even before 71 years of corrosion, you need to build up the mounting points for control arms, spring mounts and shocks. The frame is also not very rigid with few cross members, none under the rear half a very beefy. It relies on the integrity of the box section for what torsional strength it has

It would be much easier to put a Camaro width rear axle under there with leaf springs and a sway bar

What are front suspension plans?

Re: 4 link axles.
 

Not really sure as what are my ultimate goals, but the over arching idea is. I want the 54 to perform like a muscle car with a catalog of bolt-on suspension parts thrown at it.

I like to do road trips, and go to the mountains. So I dont want it to be a the lumber bus.

By my place. I have the Angeles crest highway which I have taken to go visit family in the desert. By Bishop there is south lake. Where the roads are slightly curvy. Also the 395 just south of the NV border. These are places I go often enough that I want to have a competent vehicle to drive through. I have Zero illusions of being on the lead lap.

Also I have a tendency to drive 75/80 mph on longer drives just to make some time. So if I have to slam on the brakes. I want to stop pretty quickly, and not roll into the ditch.

The front is likely to be a Jag clip I have, but I also have a Chevelle front clip too. Either works good enough for my fevered dreams. Just want to bring the rear up to spec as much as easily possible. As I may want to bag the car for fun

Never used them but there is a company in the southeast called "Fatman Frabrication". As I recall they offer basic Mustang II front kits along with upgraded kits.
I think they offer rear end 4 link kits.

Re: 4 link axles.
 

They sold out to one of the employees about 4-5 years ago, and that guy ran the business into the ground, they're shut down now and people that paid for parts never got them towards the end. One of our customers got ripped off by them.

Re: 4 link axles.
 

Have you looked at the Chris Alston Chassisworks site? They list set ups for your car in their catalog as well as lots of DIY components.

Re: 4 link axles.
 

Not extensively.

I was just looking at entry level parts instead of full blown kits. Which to me they are more known for.

I got the Vid from my son, but Saturday we got the car. So I had a decent look at it, and it needs the 4 inch rear block removed first. Then I am going to lay out build process to move it towards a highway car I want.
