1972 Blazer Coil Spring Suspension - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Frugalmeyer** · 11-22-2018, 11:02 AM

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.

**Frugalmeyer** · 11-22-2018, 11:07 AM

Took some measurements and pics of the front end before I started.

What’s the plan? Always liked this one

I am missing a security token, sent a message to the administrator to see how to fix it. Will not allow me to post photos at this time.

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

Getting everything ready for the front coil over suspension.

gringoloco · 12-02-2018, 02:47 AM

Nice. Which kit are you using?

**Frugalmeyer** · 12-02-2018, 11:37 AM

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

**Frugalmeyer** · 12-02-2018, 11:44 AM

Checking the ride height, wheel offset and look.

**Frugalmeyer** · 12-02-2018, 12:00 PM

Changing to four wheel disk brake master cylinder, proportioning valve and hydro boost.

**Frugalmeyer** · 12-02-2018, 12:13 PM

Measuring and preparing rear of truck for coil spring rear end.

**Frugalmeyer** · 12-02-2018, 12:17 PM

Getting ready to remove POL cross member and go back to original.

**Frugalmeyer** · 12-02-2018, 12:21 PM

Modifying cross member for exhaust pass through.

**Frugalmeyer** · 12-02-2018, 12:24 PM

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

**72gmguy** · 12-02-2018, 04:03 PM

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

**Frugalmeyer** · 12-02-2018, 05:11 PM

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.

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

**Frugalmeyer** · 12-02-2018, 05:30 PM

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.
