any body running one? if so how was the install or did you fab it up your self and how hard was it and how much did it cost?

JeepCoMJ

interested too...but for a comanche.

I'd guess it's only as hard as a front longarm.

i found one online but its 1500 and id rather build one than buy one for that price

There's a bit of fabbing to do in order to run coil springs.

JeepCoMJ

a couple buckets and some plates. to run coils...big deal.

but if you just run coilover springs then you only need a couple mounts.

im just wondering about the triangulation and the length of the arms and stuff like that and where they were mounted

not really.

exactly.

rockkrawler makes a kit $1500

You didn't watch extreme 4x4 this weekend? Ian showed us all how to build a rear 4 link!! it was a good show... should have seen it!! there are several variations of the 4 link. do some research elsewhere if you don't find anything here. i wouldn't spend 1500$ on a kit. just build!!

claygrassmann

lol i did watch it im just askin around for some ideas about where to mount the endlinks, like if i should weld them on the unibody somewhere or make up a crossmember to mount them to or something like that

a1racer

the thing you have to remember is that we have unibodys and he was working with frame rails. so there is a lot more work to it than just slapping on some mounts and calling it a day. that is why the aftermarket kits cost so much

muddeprived

there's more to it than that.

kilbrethj

yes... being these are uni bodies you are def gonna need some support under there!!! if it was me i would build a new cross member to go between the somewhat frame rails and bolt it and weld it. then make a plate to bolt/weld to the cross member then put your 4 link mounts to that. but i would def tie it into whatever you can find under there( frame rails, floor, pretty much everything!!)

go play with some 4 link calculators to see whats involved in building one. not as easy as slappin some rod ends on some tube and making the link brackets wherever they fit

JeepCoMJ

my response was directly geared towards the following statement by you:

the fab work for coil buckets is SIMPLE. that's easy as hell.

the fab work for your mounting points isn't too hard as long as you're a good welder and fabricator.

the geometry of the setup is the hardest part, but frankly I don't think it's too hard to get right. if you do your setup correctly, you may be off by 1" or less. and if you're smart in your design, they're adjustable to make up for that 1" without stressing the joints too much more.


I don't see why everyone craps over building longarms. fabrication is NOT that big of a deal. cut, grind, fit, repeat until it fits, then copy for the other side.

I'm doing a wishbone 3-link in the rear of my MJ when I'm to that point. the upper link will have it's body side mounts behind the axle, with a trussed mount and a superflex joint at the center of the axle, and the lowers will be coming from towards the front of the truck to the axle, with the superflex joints on the axle and bushings on the body.
that design is so that I don't have to move my gas tank, and it should perform extremely well under stress. it will be coil-over shocks rather than coils with buckets.
