If they are about 2 inches high, I’ve seen similar parts under the rear of 1960s big cars on the frame behind the rear wheels for the rear axel to hit if you go over a big enough dip in the road to bottom out the suspension.

Yes, Dave, they are 2 inches high, 1 1/2 inch wide. I wonder if any boat trailers had suspension bumpers like the cars you mentioned?
