I'm not overly impressed with most linked suspensions people just piece together. You really have to do your research and get all the geometry perfect to end up with something that works right. Most the time getting that link geometry right involves building the chassis around your suspension. I have wheeled with a lot of people that don't have their roll center high enough and there junk flops way too easy off camber. I have also wheeled with a lot of people that don't have their squat values even close to dialed and their pile hops like crazy, while my leafed rear end with proper setup on the wrap bar hooks with no hopping involved. One particular person had the proffits kit and the thing just didn't work, which is why i'm not a fan of prefabricated link geometry. Not trying to steer anyone away from getting their kit all the brackets and stuff is great but make the geometry work with your particular truck, COG wheelbase, that sort of stuff.
I would not use 80 parts all those links are way too short to start with, your roll center and anti-squat would suck…
thats the part Im' afraid of with the links. I'll get the number wrong and it will flop and wheel like crap...But in all honesty...it can't be *that* hard...I suppose if you model it "similar" to a heep rear, it should work well.
You really think the 80 rear would be all wrong??? There's a page that someone swapped the full suspenion (i wouldn't do the front) and it seems to be working real well on a 40.
I know the springs wouldn't work..but it's all basically geometry...plug it into the calculator and go correct? The lower links have to be close to 34" or in that range. if you used them top/bottom and did the geometry on the 4 link calcs....
I know the longer leaf springs would probably be the easiest. maybe using stock XJ rear springs, or dakota rears? But I don't really want to mess with flipping the rear/doing rear d-shafts right now...so that might screw me over.
Because even with the longer shackles...it still doesn't really flex for poo at the rear.
