So I just got my RE 2.5 installed (93 YJ) and everything went mostly well except I had to flip the rear shocks upside down because they wouldn't fit at the time. I've since been told that they should fit after the full weight of the vehicle is on the axle but I haven't had a chance to try that yet. But at any rate, it's incredibly bouncy in the back end. My other thought was that if I remember correctly the original front leaf spring packs had 5 leafs and the rears had 4. With this kit, all springs had 5 leafs. What might be the more likely cause of the bounce? Can upside down hydros really make it that bouncy or is more likely the leafs? Anybody have this issue? TIA.
UPDATE: Ok, so today, I dropped the air pressure down to 25psi from 35psi. Apparently when I had the tires mounted they put 35psi in them. Ouch. I also pulled all of the leaf spring bushings out and greased EVERYTHING with some lithium grease. Then I left all bolts loose, set the Jeep on the ground and bounced it several times pretty good, then torqued all the shackle bolts to 50 ft-lbs as suggested. It definitely rides MUCH better. I would imagine after some more miles it will be even better but for now I'm very happy with the result. Thank you all for the ideas and information!!

UPDATE: I flipped the shocks and it only seems "somewhat" better. Unfortunately, I can't even tell you how tight the shackle bolts are because a friend of mine was putting that together while I was working on the front. What should the shackle bolts be torqued to? I'm guessing they should be greased considerably as well, right?
I've got the RE 2.5 ED, six leafs in front and six leafs in back on a 93 YJ and I have nothing but good to say about it. The ride is better then stock, no bounce. The flex is excellent. I also had to mount my rear shocks upside down.
flipping ur shocks gives more wheel travel? does that require chaning shockmounts or just flipping the shocks?
Flipping your shocks will not effect wheel travel. Shocks can only effect suspension travel in two ways. They can only extend to there max, and compress to there minimum. The direction you mount the shock does not change either of those. Now if the body of the shock is hitting something preventing the suspension from moving it needs attention. Really the only things that should determine your wheel travel are your bump stops and your springs and how much they droop.
Hydro shocks are not completely filled with fluid there is some air inside them. Some shocks if you mount them upside down the air pocket is where all the valving is. This makes your shock no longer hydraulic it is just some springs mounted on a rod. If the valving is just getting air passed through it there is no resistance to slow the shock down properly.
