what springs to use with 1/2 tons?

i just bought my first jeep. it has a d44 front and dodge 9.25 rear with what i believe is cj7 lift springs. it also has 2.5" shackles. the only problem is it feels like the damn axles are welded to the frame! what can i do to make it ride smoother?

Wrangler and Wagoneer springs work pretty good. How are your shackle angles?

The axles have nothing to do with the springs/ride. Your ride would be the same regardless of what axles were under it.

More information is needed like how tight are the shackle bolts? How are the shackle angles, as mentioned? Any way to tell what springs it has?

Could be something as basic as shocks that are too stiff. I've found the high pressure nitrogen charged shocks can be too stiff for light CJ's. I use hydraulic shocks.

I took the front shocks off and it rode the same. i don't know a much about straight axles but the shackles looks like they're facing the wrong way to me

Yes those are facing the wrong way. Someone messed up determining the location of the fixed spring hanger.

What scares me is those lift blocks between the spring and axle. They should never be used on a front axle.

How tall is that thing? It looks like it has a body lift also.

its lifted between 10 and 12 inches. the rockers sit higher than the 37's. i plan on using different springs to eliminate blocks up front but im not sure of what leafs to use.

You have 7 leafs in those springs. That is a very heavy duty or "Severe" duty set up as CJs came with between 4 and 7 leafs.

Unless your CJ is loaded up with the V8, hardtop, winch, huge bumpers and a dog you will not get enough load on them for them to bend. I see you have a V8 auto but otherwise the sprung weight (that is everything above the springs) does not appear very high as you have a canvas top and skinny bumpers etc.

This may be the source of your problems. You may find it rides a lot better with only 5 leafs and that someone has grafted on full size size pickup truck leafs that are meant to carry a lot of weight.

However I would also sort out the shackles, get them stock length, and position the hangars at the right position. Then you might get some flex. If you are going to replace them get the military wrap option so it is a complete eye on both ends, they will not break so often.

Get rid of those blocks and correct the shackle angle and I bet you will feel a big difference. Also, if this is the kind of work that was done by the previous owner I would not drive this Jeep around before double checking everything like steering, brakes and brakelines and quality of welding on critical components.

By the way, the shackle angle should be like it is now but tilted the other way.
