I have done a 5" frame chop drop and 5" extend to the front IFS to give a little lift and clearance for 33" tires (it now has clearance for 35" tires from droop to stuffed up in the wells and from lock to lock)

My question is, what to do with the back? I have a rear driveshaft with heavy duty u joints and has been extended 3" for a custom lift I did on one a few years back that has since gone to bigger axles.

I run a lotta powerline trail that can sometimes get whooped out and I like to go to the dunes sometimes.  I think I should make the back a long travel.  Can this be done without a slip yoke eliminator and CV driveshaft?  I have a buddy that we did a prerunner ranger and his rear suspension is a giant racing kit with deaver leaf springs with 18" total travel and the kit uses the stock driveshaft with a slip yoke.

I am not looking for massive flex, just lots of up and down travel.  Im thinking that if I make the rear a 4 link (with coils) with the closest to parallel links and as close to the u joint pivot points as possible I should be good with the slip yoke eliminator as long as i limit the articulation so that the driveshaft doesnt pull out to far when maxed out.

questions, comments, and suggestions would be helpful.

oh I also have a set of coils that i got a while back, i think they are 6" lift coils for a jeep cherokee (they were perfect on the rear of the last geo that i used them on as I often have 2 adult rear passengers) and a set of 14" travel bilstein 5150's that I would like to use for this (do i sound cheap for wanting to build my suspension around a driveshaft, coils and shocks that i already have?

Sounds like you are on the right track, the long 4 links set
to the pivot point of the front u-joint should work well

I ran into something similar with my Zuk. I did not want to go with a SYE kit due to the labor of installing the kit. I ended up calling Tom Woods driveshaft. They took my stock SY and machined it to a double cardan cv joint drive shaft.



With it mated to the stock SY and flange it allows removal (unbolting) of the shaft for trail fixes WITHOUT removing the SY stopping that annoying oil loss.



The back half is a upgraded U-Joint that should hold up to any thing me and the V-6 can lay into it.

OK, so I tried the pics twice..... They show up good in my gallery, check them out there:

Wild is right on..  I was messing with My trailslayer suspension last night and it will drop wayyyyy out.. fully compressed I have a shock length  of about 12 inches.. Full drooped, limited by the e-brake cables, and brake lines the measurement between the same two points was over 35".. No that isn't really reasonable I know but the other limiter was the drive shaft, a shaft with high flex joints should solve that problem..
