A shock absorber for fifth wheel hitches for pickup trucks has a bushing embedded in memory polyurethane elastomer confined within a metal frame. The shack absorbers are mounted by brackets on the fifth wheel hitch support frame. The bushings receive pivot pins terminal to a cross beam mounting the couple assembly of the hitch. Both bushing and shock absorber frame have projections extending into the elastomer for better engagement. The projections can be studs or planar lugs. When the projections are loops of wire welded to the bushing and frame, the elastomer flows into the loops providing better engagement.
