Howdiy's halfassed 4 link

[MNorby]

yeah, why do you want to do a wishbone upper?

 

[howdiy]

Why do you have to use a wishbone upper? What is up with the tweakage on the lower link mounts?

Wishbone-below

On the lower mounts I thought I would be able to get away with the mounts facing forward but it put the joints into way too much of a bind. I wasn't expecting my lowers to have this much angle. It's not a bad thing though.

I made some tabs out of 3/8 and will finish the lower mounts tomorrow.

It would have just been easier to package it, My links aren't that angled so the nuts touch each other making me have more separation.

I've been researching though and wishbones kind of suck, So I'm going to get some regular nonlock nuts and weld them to the tab and then cut of the excess bolt so I can get them as close as possible.

I ran the numbers in the calc and even If I have them as wide as possible on the mount pad they still check out. I should be able to get less than 6" separation though. Which will bring my roll axis angle to -1

what about these?

Good idea.
Thats what Ive used. Front and rear.


Now youre going with a wishbone?
Why?

 

[howdiy]

Not anymore, read above

The ballistic buckets won't really work with what I'm doing. Not much room

 

[odin]

My junk is also a Chevy
How does the rear of your frame have less room?

 

[howdiy]

This is close to the final numbers

 

[howdiy]

Paint is going on tomorrow

All that is left is some gussets, machining the upper links, and the upper coil buckets

 

[howdiy]

Painted and got a little extra clearence. I spent about 15 minutes with a sawzall and a grinder

I'm going to buy a cover also, I'll paint the housing when I paint the new cover

 

[sawzall]

Yeah I was thinking I will probably have to raise the timbren mounts and the truss would do that. I'm not sure yet, I'll get it under the truck first








And I think I'm going to do the upper mounts like this

I think my cousin has some adjustable ones of a race car that will work.

Is this a common setup? It seems like the all-thread would just buckle or bend, ever hear of that happening?

 

[howdiy]

Yeah racecars use them all the time

Every nascar has them on all four corners

I was just looking at your build thinking I have seen this before.Then realized I have on pirates.Looking good.I have thought about doing the jackscrew method on my Cj/buggy thing.Would be usefull for adjusting rideheight when loading it down for camping and not just a trailride.
Scott at rockstomper had a this set up years ago on his yota truck.Seemed to work fine.

 

[howdiy]

Almost done, just need to make the upper coil mounts and weld in my lower cross member.

I'll run the numbers one last time when I got it all to know what my AS numbers are for each hole

 

[SUPER'BURB]

Your work looks very good but.........
I was looking at the pics and thinking (probably a bad idea) that the coils don't look like they could compress much more with the load of the rig on them.
Am I right, wrong or do I just have no idea what I'm talking about/looking at?

 

[howdiy]

They are progressive rate, the upper part will collapse and then the next stage will begin. All together there are 4 stages

There is a lot left in this pic

I need to get some decent shocks. I think I'll get some FOA's so I can get them custom valved.

 

[Adventurous 4x4]

I am really curious to see how much droop you get out of the springs.

 

[howdiy]

Me too, Hopefully it's pretty decent, They compressed about 5" with the weight of the truck on them.

Well at least I was correct, I don't know what I'm typing about .

 

[Adventurous 4x4]

They should compress quite a bit less on my tubed out K5. I am a James Duff dealer so I should be able to get the springs cheap enough to try them out. I like the progressive rate they have too.

 

[howdiy]

Yeah I imagine

Just bouncing my truck around they seem like they may be too soft but I'm not sure if it's just the soft first progressive rate I'm noticing. I'll have to drive it around to find out.

It's pretty springy too with no shocks

 

[howdiy]

Heres a pic today that I took when the coils are under no load

I imagine the weight of axle pulling down will it a few more inches
