Rear shock mounts (was" How best to raise back end?")



When I bought my 64ragtop, it had air shocks on the rear axle. Also, a heavy trailer hitch bolted to the frame. I didn't ask the previous owner how much tongue weight his trailer added, but dropped that hitch assembly right away. Then the rear of the car rode like a truck. I don't remember how much the air shocks were carrying, but the new "heavy duty" ones really improved the ride and handling.

Seems to me that the rear shock mounts on most of our cars were not designed as load bearing parts (any old-time auto chassis designers out there??) My worry is that either air shocks or coil-overs will stress the shock mount area of the chassis and i just don't like the idea. Note, this is personal preference, as surely there are lots of folks who use them for that, and I have not heard of failures. heck, it may very well be that shock mount failure from this king of overloading just "ain't no big deal". My cautious nature just tells me that it's not smart to overrule the chassis designers, thinking that I know better then them.

Good luck and best wishes to all. I'll re-arch my rear springs or buy new ones, thanks.

All you guys that poo-poo air shocks....can you explain the difference between coil-over shocks holding the car up and and air shocks holding the car up? Both put the same "pressure" on the shock mount

I agree with Herb  100%--Do not do extended shackles.  Bach in the raised
rear days, guys would do the shackles route and  that would result in the
shocks being fully extended to the limit --next thing would be springs that
were straight or arched down.  If you have strong upper shock mount, the
adjustable spring over shocks  would probably work.

Stay away from them, probably the reason they are hard to find, I'm sure.
Re-arch or replace are the best & safest options for your spring issue.  I
have had good luck having my springs rebuilt and others on here not so
much.

There are other options such as air shocks or air bags but all they do is
cover up the problem.  Air shocks have been the cause of many a broken
shock mount because the shock mounts were never designed to carry the
weight of the car, just the shock.  But both are viable options if that is
the path you want to take, but both were designed to assist the spring in
caring excess weight not to replace the springs job.

Again stay away from long shackles.

My '62 Sport Fury sits low in the back end by at least 2-3 inches, I'm
assuming because the leaf springs might be worn out?  We are thinking about
getting leaf springs re-arc'd (there is a guy in Great Falls MT that does
it), or perhaps putting on a longer rear spring shackle.  I looked on-line
for a longer shackle but didn't immediately see one.  Any thoughts on where
a guy could get a longer shackle, or whether it's better to have springs
re-arc'd?  Thanks - Wade
