Once you get the new springs on, you will need to get the front end aligned for the new ride height.

The OP doesn't say what chassis he has.

If it is a workhorse and the SumoSprings are the airless yellow, solid poly urethane type, then there should be no affect on ride height...

I installed these on my rig two years ago. I did feel an improved ride that I would describe as firm and more stable. The kit came with a set of shims that basically extended the reach of the Sumo spring closer to the axle. Using these shims made the ride harsher. Removal of the shims improved the ride to the above description. Either way caused no height change as the springs do not contact the axle.

They are the yellow ones that bolt on to where the old bump stops are located.
They way I understand it they have each a #1500 weight limit and will be almost touching the lower frame when bolted into place. When you hit bumps they are suppose to dampen the ride. We will know soon. I will take pics when I put them on.
