1972 Blazer Coil Spring Suspension

I came to the conclusion that I was not totally happy with the ride and braking of the stock suspension and decided to perform some upgrades.

Usually that happens when your pics are too big or too many. Try reducing size or post no more than two at a time

Re: 1972 Blazer Coil Spring Suspension

I chose QA1 because I did not feel like removing the cross member.

Thanks Gringoloco. I tried posting four photos instead of five and the security token did not block me.

Re: 1972 Blazer Coil Spring Suspension

Why the switch back to the stock trailing arm cross member? Something you didn't like about the pol version. Just curious.

Re: 1972 Blazer Coil Spring Suspension

POL cross member is flat and the rear control arm brackets are angled.

Stock cross member is angled and the brackets are straight.

Since I am going to a TCI rear coil over kit I noticed their rear control arm brackets are straight and had to go back to a stock cross member.

Re: 1972 Blazer Coil Spring Suspension

Very cool. Are you having to modify the upper coilover mounts to work with your 4wd frame?

Re: 1972 Blazer Coil Spring Suspension

I am in the process of having a custom set of C-Notch plates made with upper coil over mounts. I will update the thread when they arrive and I begin to install them.
