  • add a leaf vs. air bags

    So my rear end is sagging and I'm not sure the route to take.

    I've got OME heavy duty springs in the rear that are still pretty soft. I really like how they handle, but with the hard top on they're just too soft. Where the CJ has become a daily driver I've got to get the body roll and sag under control. The question is, do I run an add a leaf or a set of spring assist air bags.

    I'm liking the idea of the air bags due to being able to deflate them when the top is off and not have a harsh ride. But I'm worried about them limiting travel and flex as they would effectively tie the axle to the frame.

    Is the add a leaf not the big deal anymore? I would run the 4wd add a leaf that has teflon pads on the ends to aid in spring flex.

    What are your thoughts?

    I've thought about the airbag thing myself. The Scorpion line of rock buggies (ya know...the guys who started it all) run air bags.

    An air bag only ties the frame and axle together as a spring does. If it's deflated, it should not have much impact on articulation unless it takes up too much space. Interesting idea indeed!

          Add a leaf will help a little, depending on your sag. I had the same thing going on. Tried the add a leaf. After 1 month decided to get my springs resprung at a local spring shop. It was cheaper than buying new and retained the original look to my Jeep. Yes it does ride a little stiff, but it is a Jeep not a Caddy.

            I'm assuming that they're running full air suspension...not air assist. If that's the case the bag would be much bigger and probably much more flexible than an assist bag.

            The other concern I've developed is the 4-5" of lift...not sure that a stock CJ assist bag would work. May have to find a system that has more bag to it and customize a little.

            Completely understandable.

            But I don't believe my springs are sagging. I've had this issue from day one but never addressed it because the hard top was only ever in place during the winter and I maybe drove it once every two weeks or so at that point. When the top comes off, things are like they're supposed to be. OME springs are just soft to start with.

              I needed help on the front of my CJ and bags would not fit. I went with Monroe Air shoocks on my Jeep. I just found a set with the right collapsed/extended dimention for my lift and bolted them on. When my plow is on I adjust the shock for the right height by adding air and in the summer I let some of the air out and I'm good.

              Good for about 1200 extra pounds.

              I got mine at NAPA and they have a guide for finding the right shock looking at mount and collapsed/extend dimentions. I think you can find that chart online at Monroe also.

                I used a set of these on the rear of my XJ a few years back. They seemed to work fine and held up pretty good offroad...a much easier fix than bags or springs....

                *EDIT*

                Decided this was the way to run for right now. $57 bucks and I should be set. I figure I'll get these installed and then make a decision if they do the job or if I need to go to something more beefy like an add a leaf or air bags.

                Good call John...I didn't even think about these
