I've always heard "just say no to a pinion snubber" they're the bandaid eqivilant to slapper bars and not that great.

good shocks, correct pinion angle, and clamp up the front section of the springs, while removing clamps from the rear is what I've always heard recommended.

I'll be doing that myself here pretty soon, my dakota will wheel hop pretty bad especially if there a tiny bit of moisture out. through first and second gear.
