bumper hitch

ztim · 01-07-2007, 03:00 PM

I found an L shaped bumper hitch on the web meant for light trailers. Would this be okay for the '84 Delta 88? All I have to do is mount it with 4 bolts.

Think about how that railroad tie bumper is held on by two "shock absorbers" and think about the weight of a trailer tongue bouncing on it. Even a light trailer....bouncing down the road...not me.

Just my $0.02 worth, but I would see if I could find a frame mount that uses the bumper only for stability or (better yet) one that is independant of the bumper.

I looked and it seems to me the bumper is mounted to the frame. The trailer I would tow carries a 10' aluminum boat. I was looking at it price wise. There is about one hundred dollar difference. between the two.

I think GM has used the method C.J. described to mount the rear bumper since about the mid 70's. I had a '77 Delta 88 with a bumper mounted like that and the bumper fell off. It was due to dissimalar metal causing excessive corrosion at the mounting plates. The plates were steel with another kind of steel bolt and the bumper was some kind of aluminum. The bumper basically disintegrated. I don't know what the bumpers are made of now but I bet there is a similar situation because I know they still used the shocks in the eighties. Don't mount the hitch directly on the bumper. Just my 2 cents based on experience.

You guys are right. I'll hold off until I can get a Lok-tite or something similar.
