Flex help!!!

Ok this should be an interesting thread. I have this yj BUILT for the mud, but I've recently found that flexing your rig is fun and addicting! This rig has zero flexing abilities(no da right). Here's my set up..full size axles 456 gr,Rubi4'' soa, 2''bl, cross over steer, quick release swaybar, less than 1'' shackle ft, less than 1'' boomarang shackle rear, sye, with wfo torque arm. I was thinking of removing the 2''bl and adding tube fenders and cutting the rear(less than compcut). BUT I STILL have the flexing problem though.

My front left tire can come up only 15''-18'' (this is a good guesstimate)before the left rear tire comes off the ground. The right rear is not even close to eating the fender either.

I'm still going to use this rig in the mud, but I'm want flexing capabilities similiar to most of you guys. I would like this rig to be versatile.

I blame all of you for this by the way.

My question is how can I flex more with the gear I already have? Is there a way?

Check your bump stops. You might be hitting the axle on them and it is limiting how much travel your springs will actually do.

BROCKMARZULLO..Good thought but I have already removed all of them. Also when flexing my shocks look like they still have a few inches of travel.

what are your shackles torqued to? Retorque to about 45ftlbs or so.

your two biggest issues will be your springs and shocks. the 4" springs are big flex limiters. with that much arch they just dont like to flatten as easily as a 2" set. this is not the biggest issue as we all know that compression is nice but droop is where you really gain advantageous flex. again the high arch will debilitate you as the spring is, by design, at the end of its droop potential at near ride hight. anyone who says their 5" springs are flex monsters need to see what a lot of very capable leaf sprung vehicles can do.
if you are using stock shock mounting then you are wasting the potential a good soa has. in a jeep these, particularly the rear, are the biggest flex hinderances. rework these to allow for the longest shock possible. as you relive your suspension to move you will find more and more little things that hinder flex. the simple orientation of your shock eyes can cause premature binding. they need to be mounted with the eye perpendicular to the axle tubing. this is 90* from stock. every little thing helps. undo the spring clamps and this will let the leaves separate during droop. make sure our e-brake cable isnt hanging you up. a slightly longer then stock shackle also helps. i like them no more then an 1" longer. make sure your shackle move freely by hand. do not loosen them to 45ft/lbs. this is wrong. if they do not move freely at factory spec then they are designed wrong. rework them until they are right.
....and you are going to have to cut some of that sheet metal. 40s just wont fit into the wheel wells period. if you have space between your tire and body at full compression then that is waisted space.

Thanks for the help FRATIS..I called the guys at WFO today and they said the same thing. That the 4''rubi was the issue. So I'm bout to order a BDS 2'' leaf set and a set of boomarang shackles for the front. So I should be flexing nicely afterwards.

thats not the issue,Its that RE 4''lift springs have so much arch that they are too stiff to flex like the softer2''lift springs.

If you have trac bars installed they will limit flex. I'm guessing you already have those removed though. As mentioned, I bet your leafs are to stiff based on what you have said so far. Guys that have the good flex are usually SOA and 0-2" leafs. If you leafs are new get out wheeling more and flex them. One they are broke in it will ride better and give more flex.
