More flex out of my yj with 3.5 spring lift.

I have a 3.5 inch leaf spring lift on my yj and it sucks when it comes to flexing, its so stiff it just lifts the tire of the ground instead of it falling. Im all atock besides the lift and tires. Any help? Oh and keep in mind its my daily drive i drive 80 miles a day in. ...... .... thanks..

Revolver shackles? Might not be great on a DD though

Subscribing.

I just recently got a 3.5" BDS lift with new shocks too and the ride is stiff still. Haven't flexed it but I'm sure it'll do the same thing yours does.... Wondering if this will always stay that way or if we just need to wait and break it in

When flexing did you disconnect your sway bar?
Trac bars still connected?
Shackle bolts torqued to spec? (If there too tight they won't work right)
Are your shocks the right length? (Too short they will limit the droop)

Start by removing trac bar and making/buying sway bar disconnects.

Trac bar just unbolts. One bolt on the frame the other bolt on the axle. It will affect your ride, it will make little smoother. If you don't like just put the bar back on. As for discos I use a pair of JKS ones for a TJ.

Ill have to check into that, a smoother ride would be nice. I never ran a track or sway bar on my cherokees and they both drove great just a little different in curves.

Trac bar is required in a coil spring setup like on an XJ.

I ment sway bars on my xjs i just read that over lol. I have a 98 with a 4.5 in super flex lift and the top bolts on the sway bar kept coming loose so i finally took it off and loved the results. I wished my yj flexed that much. Im gonna try taking the rear track bar off and checking my shackles. I really dont wanna remove my sway bar but will if needed.

for the front unbolt the lower bolts on the swaybar and tie up the sway bar when off road. it will help in a big way. You will want to to flex test it to make sure your brake lines are long enough. Then re-bolt the sway bar when back on the road. I don't run either trac-bar or have the sway connected on mine.

Any of those lifts will flex fine. It's the track bars and swaybar that are the limiting factors

Ok that's what if assumed lol, I was going I go with the 3.5 to hopefully stay economical, also cheaper. Next would be cv shaft/SYE and to regear. But yeah I'd say the shocks r stiffer till broke in

The main problem after the trac bars are gone is these are all "military wraped springs". The 3.5 lift is good and then add at least 1" lift boomerange shackles for the flex. Factory shackles will limit the rear axle tremendously!! longer shocks and sye are good to look into after the shackles but ran a 3.5 + 1.25 shackles wo a sye but my rear shocks were my limit stops for droop from lack of a sye.
