Heavy duty rear shock mounts for stock application C 20 with coils? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My 69C 20 has lower shock mounts that are cracked on both sides. I want to put some good Bilstein Shocks on this rig and I don’t see those original mounds holding up even if I replace them with original NOS. I can find options for lowered trucks but nothing for stock. I have also heard of shock relocation, is this a good idea for a stock application as well?

Do the No Limit shock relocater kit and you will be very happy with it even on a stock truck.
It's worth every penny!

It moves them to the outside the frame rails and will make the truck feel much better in a curve. I took the rear sway bar off I had because it was in the way of the shocks mounting. I was pissed I was going to loose it but after the install and driving the truck I didn't need it anymore.

Does the no limit kit require a different shock absorber than original?

I don't think so but you can call them and verify that!

There is a reason that your shock mounts have cracked and hundreds of thousands of other trucks haven't. Some of the reasons are driving with bad or broken shocks, having the wrong length shocks installed, or driving on very bad rocky roads where the mounts take a lot of physical abuse, or driving the truck in a extremely overloaded state, or driving on bad washboard roads way to fast, and lets not to forget, jumping the truck, aka Dukes of Hazard.
For a stock truck in good mechanical condition the factory shock mounts are completely up the the job.
I would look to find the reason for the failure and replace the bad ones with good originals before dropping a bunch of cash on some parts that weren't meant to be used on a stock truck. If you are planning on dropping the truck and doing other suspension modifications to make the handling better then by all means go and modify the mounts, but otherwise I would put my hard earned cash elsewhere.

Decades ago I worked in retail automotive repair and there were still plenty of these trucks in use daily. Broken rear shock mounts were a very common problem on these trucks. Two reasons make me seek an upgrade:

All dirt road where I live with plenty of washboard. Very hard on shock mounts.

The Bilsteins are a very tight shock, that are much stouter then the original mounts were ever designed for.

The relocation kit places the shock absorbers in a much more reactive position that should greatly help handling (?). I’m not an engineer, but I’m truly curious of the pros and cons of both set ups.

Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
