Upgrade from OME shocks??

Given the approximate weight of your truck, the heavy coils in the front may be too much but I don't think that's the main problem. I think the OME Nitrochargers are valved too stiff. I felt that way on my own truck when I had OME and it's a heavier truck than yours. The OME shocks are valved to try to suit a very wide range of build types and uses, and generally tend to be better suited for more weight. As a result there are bound to be places where they are not ideal. The other problem with the Nitrochargers (IMO) is if you are running them hard for more than 30 min or so they start to fade and lose dampening.

I am confident that with some different shocks that are better suited for your vehicle and weight and use you'll find some good improvements. I'm biased toward the Slinky Stage4 shocks that are 2.5 bodies with remote reservoirs and 10 stiffness settings that are easily adjusted. They are one of the more expensive options but will give you the best ride and performance. If you are on a lower budget I would consider the Slinky Stage1 2.0 shocks. They are roughly the equivalent of a setting of 4 (out of 10, 10 being stiffest) when compared to the Stage 4. After that, if you're still considering cheaper solutions although the cost doesn't change too much at this point I would look at the Tough Dog Foam Cell shocks from Trail Tailor.

A couple other things to consider. Your OME coils are likely linear rate springs. There are several dual rate coil options out there now. It's just better spring technology and will allow a lighter spring rate for small bumps like what you have on the road. These will nearly always ride better than a linear rate spring that has the same rate through it's range where they will work fine on big bumps but small bumps don't apply enough force to move the spring much which will transfer the shock to you. Or switch out to the medium rate OME in the front (it will still be linear but won't be quite as stiff.)

This is just personal preference, but I like the Factory rubber bushings better than Polyurethane caster bushings. The poly bushings are also a stiffer material and while it may be minor, they will transfer more vibration etc and will feel stiffer. I'd consider caster plates instead to correct caster and look at switching back to rubber bushings.

I also probably run lower tire pressures than most people. I typically run 28-30psi on the road. Even dropping your pressures from 35 to 30psi will help some too and shouldn't have any real affect on wear or fuel economy.

Those are my suggestions.
 
The truck is first and foremost a daily driver. I bought the springs based on Slee's customer service. They recommended the weights. I am thinking about looking into better shocks to see if I can soften up the ride. I was expecting the ride to be too soft after adding the lift and tires.

plus 1 for the rubber bushings versus poly castor. I went from worn out castor bushings that were spinning in the arm to factory rubber and man-a-free drops brackets and the small bump compliance went WAAAY up.
