'73-'87 ('91) 1/2 and 3/4 Ton Chevy Truck Rear Shock Brace

The rear shock mounts on '73-'87 ('91) Chevy trucks are setup in single shear and that makes them another spot in the frame that is failure prone.

To prevent the frame from cracking at the rear shock mount location like this:

We've created this kit to mount the rear shocks in double shear, spreading the load across more of the frame and helping prevent damage:

GU38017 Rear shock brace

For '73-'91 GM Full size Blazers and and '73-'87 1/2 and 3/4 ton pickups. 

Does not fit K30's or Suburbans.


Installation requires aftermarket studs, see more on that here.

Drilling four holes required.

Our shock brace is a preventative piece meant to keep the shock mount from breaking, not to fix a broken frame/stud.

The frame and shock stud need to be in good shape (or repaired if broken) before installing our brace.

GU38018 Replacement shock stud for '73-'87 ('91) Chevy truck

Installation of our shock brace requires an aftermarket mounting stud.  If your shocks have been replaced in the past, they probably already have these.  Aftermarket studs vary, so the hole in our brace may have to be drilled larger to accept existing stud.  Our brace and our stud work together without modification.

If the shocks are stock, the mounting stud will have to be replaced (the stock "stud" is usually part of the shock bushing).
