HAHA. Hey thanks for helping me out the other night. I put up my measurements and 3D rendering in the extreme suspensions section for critiquing and scrutiny.

Hope you have better luck with your build the rest of the week.

here is some of that info I was telling me about for the 4 link stuff maybe you can find it helpfull sure helped me alot

As far as four link stuff goes, here's a clip from a write up I did:
From talking to many, many people with linked rear suspensions it seems that anti-squat percentages between 50% and 100% work well in the rocks. Too little anti-squat and your rig will want to flip over backwards, too much and the axle will try to drive under the truck and it will hop.
Keep your roll axis angle as close to 0 as possible. If your design necessitates a few degrees of roll axis angle it will probably be ok. Having lots of roll steer sucks.
The COG height and roll axis height should be close. They don’t have to be exactly the same but if they’re off by a lot you may be in trouble.
Some will recommend that your uppers be ~70% as long as the lowers, this helps keep the antisquat numbers consistent through bump and droop travel.
Equal length upper and lower links will keep the pinion angle consistent throughout the suspension travel.
You don’t need to triangulate the links like I did, many people run links that are parallel with the frame (straight) and only triangulate the uppers. Some people converge the upper links at the frame side and keep them wide at the axle.

Here's the whole thing, pretty long read.

My anti squat is 77% and I like it a lot. Wouldn't change it. Longer links will keep your numbers more consistent throughout the suspension travel (there are tabs at the bottom of the four link calculator that show you how the suspension changes as it cycles) but generally are lower clearance. I think mine are ~32" and they are definitely on the short end of what most people do.
Keep the links as flat as you can, keep the anti-squat between 50-100%, triangulate the links at least 40 deg, keep the roll steer low and you'll be ok. There are always compromises but think about making brackets off of your existing axle and frame to get the links where they might work better. It's not easy working with an existing frame and getting numbers you like, measure on the truck, put it in the calculator, go back and look at the truck, etc. You'll find something that will work fine.

worked on the truck today for about any hour. now comes the hard part LINKS.

Looks like you invested some $$ into jack stands too....lol

Looks good so far!

 

[JeepRecoveryTeam]

Yea I got those big 12 ton ones when we did some work on my dads motorhome but yea its like jackstand heaven in my garage cant wait to not see any under there.

any updates

JeepRecovery, Very nice. I love reading about builds like yours, great way to learn. Wondering if you could explain your 203/205. Kinda confused on how your able to run the chevy drivetrain and hp60(driver side)?

I would assume that he has a cehvy NP203 (to match the trans adapter and the small cehvy output shaft) and the rear case is a Ford NP205 to give him the drivers drop to be able to run the Ford front axle.

^^^ Bingo!

 

[JeepRecoveryTeam]

You got it he nailed it. yea got some progress frames done links are planned and mocked up need to finish truss front and rear. havent been out there to much because the wifes family was in town but there gone and ill be back out there. need to order coilovers and full hydro and efi for the 350 and put the cab back on sound easy enough

 

[JeepRecoveryTeam]

well I have been gone for awhile havent posted up any progress well... because there is none I picked up a 96 f350 for a tow rig and have been working on that think for over a month now. but soon enough ill be back grinding on the ranger project

 

[crawlin91]

I was wondering how your project was going. What are the specs on the f350? 7.3 Diesel?

 

[Josh40601]

definitely subscribing to this build....

Sounds like there are a few of us running the chevy setup... 5.3/4L80E/Atlas going in next winter
