Wheel hop issue

[Super73]

You don't need to go coil over if you put a well thought out suspension together.

Trailing arm rear suspension?
Stock replacement lowering spring?
What shock is in it now?

Unlike the lowering spring used on the front (short and stiff) the rears I have used are actually pretty good, not overly stiff. A poor shock will not control a soft spring and the axle well want to bounce.

I would start with am adjustable shock. Look for a Rancho 9000 that will fit under your truck. Measure eye to eye of your current shock. Find one that puts your existing length in the middle of max extended and compressed length.
