Be more specific. What was included with the lift ie control arms/track bars ?
Did you have a alignment ? (Post sheet if possible)

Tire psi ? (For a 37 is pretty low 22-25 ish)

What is your tire pressure? You should be around 25 lbs. Part of your issue is going to be the E load tire you are running. The Mud Grapplers are stiff.

I don't have experience with BDS, but nonadjustable control arms are usually a sign of cheaper lifts.

You need to be more specific to get help......what exactly isn't good about the ride? Bump steer or death wobble? vibes? or just a stiff ride? How does it compare to other lifted jeeps you've ridden in?

Typically, a lifted jeep will have a harsher ride than stock. As the springs break in, they get a little better, but it's no caddy. Also, those tires are rough and stiff compared to stockers, so that doesn't help. If you have bump steer, or death wobble, or vibes, that can and should be fixed immediately. If it's just a rough ride.....well, the best fix is time and getting used to it....

You might do a little research on shocks, and how yours compare to other offerings. That might be the cheapest way to smooth out the ride a little.

New shocks more than likely. Are they the nitro or hydro versions of the BDS shocks? Unbolt the shocks and bounce the Jeep. If it is still stiff as heck with the shocks disconnected get new coil springs with a softer rate. If it compresses easily without the shocks new shocks are in order.

Edit: Just saw that you have fox shocks. I would do what dirtman said and reduce the nitrogen pressure in the shocks. The off the self fox shocks are often a bit stiff just like the bilstein shocks. I had Zone 4" JKU coils on my JK at one point thay are likey the same ones as the BDS lift since they are the same company. The coils especially the fronts are quite stiff spring rate wise as they are only about 1.75" longer than factory JKU 18 coils yet they give around 4.5" of lift.

I would look at a drag link flip kit up front and raise the rear track bar on the rear axle at least 4", the higher the better but you will have to check for up clearance. This will reduce bump steer up front and raise your roll center for better stability and less b ody roll both on the highway and off road. You will likely need to run some 3.5" extended bump stops up front the keep the drag link from hitting the frame.

You could drop the air pressure in the tires a bit and drop the nitrogen pressure in the shocks a little to soften them up a bit. Revalving the shocks may be needed as well to soften up the feel. Rock crawling valving is very close to street valving if you off road and will give you a better ride then the stiffer go fast valving that you find in the fox and bisltein shocks.

You could also run some front control arm drop brackets to flatten out the front lower control arms for a better ride. You would want to use factory length arms with the drop brackets.

37" mud grapplers in the 17" wheel size are an E rated tire and will give a rougher ride then a C or D rated tire and with the aggressive tread you should expect the ride to be a bit rough and noisy.

Good luck with your build, hope you get it worked out.
