    Wasn't really looking, but came across a set of 4 skyjacker 3-4" lift springs used for sale on CL. These are the J34 'softride' springs. My unknown (probably Rancho) lift springs are of course stiff, with minimal articulation. This is made worse by their overall length which places them almost directly under the spring hangers (especially on the front) so that the shackle hangs near vertical - this of course is not ideal and doesn't allow for much down travel of the axle. I've never really figured out what caused the problem, other than someone may have taken a set of Rancho springs and had extra arch added to them - as I would assume a well made set of lift springs would take into account the required length for the application.

    Anyway, wondering if anyone has these Skyjacker J34 springs and can comment on their functionality. I am not looking for additional lift per se - just enough to keep my 33s and allow for some flex. My current set-up seems to be about 2-3" lift on the springs, and I have Warrior shackles that provide an additional 0.5 inches. If the springs truly are flexy (at least compared to what I have), a bit more clearance might be helpful to keep the rubber off the fenders.

    Finally, looking at the pics - its seems they only have the spring guides or 'clamps' on one end - should they have the 'clamps' on both ends?

    Can’t comment on the flex of these springs as I still have very stiff Trailmaster 4” springs on mine. As far as the clips, only need them on one end since they are pinned in the center.

    Good point...and its actually helpful for clearance with my one piece tie-rod setup if the clip is behind the axle.

    Wondering how much these will flatten under load of the jeep? The seller sent me measurements and they have a lot of arch... and are a bit short. But if the 'softride' flexes and flattens quite a bit it could work well.

    I have 4" lift springs. They are not this brand, but I feel that any high arch spring will be pretty stiff. To do mine again I would probably do spring over with stock wrangler springs. I have read here that it gives about 4" of lift and the ride is much better. Not sure you want to get into all that.

    Agreed - but it would help if the springs are the proper length from eye to eye to allow for good shackle angle. At least that would allow for some shackle pivot movement (and in my case would allow the axle to move down a bit). From my POV, it can't be worse than what I have.

    No SOA coversions for me - but I would consider the RR conversion that a few have been working on recently - but that is way down the road. I was just going to live with my stiff short springs for a long while, but I stumbled across these and thought it might be worth a try.

    I've worked on an intermediate CJ that had a high arch lift spring that had the flat "overload" bottom leaf. I don't know the brand, but they were likely the Skyjacker softrides. I was suprised that they were as "soft" as they were. Even climbing into the Jeep, it would lean a little bit. It actually rode pretty nice and the springs soaked up most of the bumps. It just leaned a bit in turns.
    If you look at the springs on CL, what I do is put the spring on the ground up-side-down (spring eyes down) and step on the center arch and "bounce" it a bit. Is it super stiff, or does it flex a bit? Not very scientific, but it gives you an idea how compliant they are.

    I've had Skyjacker softrides before and they've been pretty soft on CJ5s. Pretty good ride from what I recall.

    There is a BDS 2.5 kit for sale local on CL as well - more money but maybe a better way to go. Want to make sure I can clear my 33s (x10.5) with it and still have a bit of room for flex. I do run a slightly longer shackle (3.25" vs stock 2.75"), but that really is only 1/4" of added lift if it is even measureable. Concerned the 4" Skyjackers might be too much lift.

    I believe 4" is a lot and not needed for 33s. I've got 2.5" Rancho, 1" longer shackles (= .5" lift) and have no issues with my 33 x 9.50s.

    You'll like the BDS better and should not have a problem with 33's.

    X2, very worn out, sort of soft by now but they clear my 33x10.5's.

    Thanks guys - I am leaning away from the 4" skyjackers. Not sure that I will drop the money for the BDS on CL - this isn't a must do at this time - was more of an unexpected opportunity and I do think the skyjackers softrides have potential for good flex. The 4" is probably too much for clearance, and not worth the higher COG or the additional problems it creates with my Ross steering geometry, and it may not help with my shackle alignment or my minimal caster angle. I can't find it now, but Chris posted a pic of his flatty with 4" kit and 35s. I think these companies are a bit conservative with their tire size estimate. I guess worst case for the 2.5" route is that I would have to add a 1" longer shackle on the front.

    I did contact the BDS seller - come with all new hardware. They are a 4x4 shop, and they are cleaning out some left-over, opened items, or stuff that was ordered for a client and then not used or went a different direction. One of BDS' best features is the warranty, but they are willing to sell this out the back door as a cash private party sale - but of course the warranty might not be honored by BDS. I made a lowish offer - We'll find out tomorrow. They are just trying to recoup some cost for something that wasn't used - or maybe they already got value from the client that didn't use it. I think I am hoping they accept...

    Not sure I'd worry about a warranty on a leaf spring. What could happen. A knock off brand maybe but, I doubt there'd be any hassles with a quality product like BDS. Good luck. Hope it goes your way.

    x2 on BDS, supposed to be quality products. I almost bought a kit on CL last year but ended up doing the D30 swap.

    I have those springs on my CJ, if you want any pics let me know.
    They ride pretty well (it aint no Caddy LOL) and flex pretty good...I've been happy with them.

    Doug - Which ones do you have, the 2.5 BDS or the 4" Skyjacker?

    Thanks - I think the 2.5 BDS would be good - just a matter of if I want to spend the money.

    Previously I stated that I've had Skyjacker softrides. On other Jeep's than my -6. On my CJ-6 I bought BDS springs. They've been really nice. I'd call them about warranty, I bet they may cover them. I have plenty of room for my 33-10.5-15s. my frame is 5 inches tall so I maybe have an extra inch or 1.5 over stock but lots of room.
