Updating the suspension

I'm in the process of replacing and repairing any suspension issues on my 72 Jimmy, and I'm trying to decide on bushings and shocks. The truck has completely stock suspension, and is mostly a highway truck. I do plan on doing some overlanding in it, so I would like some give to the shocks.

From what I've read on here, it seems most are recommending poly leaf bushings, but stick to rubber for the body, and Bilstein or Rancho 9000's for shocks.

What are you guys running? Anything to avoid?

Re: Updating the suspension

Check out off-road design they have a lot of upgrade parts for the suspension. I’ve heard the body mounts squeak if you go poly. I have a set but I’m thinking of getting the rubber bushings instead. I’m having ORD build me custom springs. Nothing but good things said about their springs and they told me they will ride real nice compared to stock. Not cheap though. About $1500 for just the springs. For the shocks I’m going with bilstein only because they suggested them and they have a good reputation. Rancho makes some nice shocks too. I’ve heard good things about the 9ks and wouldn’t hesitate to run a set. My truck is original and I don’t think you can do much to fix the ride with the original springs. Mine rides pretty rough. Nearly 50 years old and they are likely shot.

Never heard of Fox shocks. I'll look into them.

Re: Updating the suspension

Definitely poly spring eye bushings. Rubber body mounts are good, but they do deteriorate (especially the repop ones made with crappy synthetic rubber). Don't shy away from the poly body mounts. Use the proper lube when installing all poly mounts and noise will not be an issue. Most people just throw them in dry and wonder why the squeak.

I also highly recommend the Bilstien 5100 series gas charged shocks. The Fox bypass shocks could definitely be tuned to give a better ride. But the cost significantly more.

Lastly, I installed a set of fully adjustable load assist air bags in the rear of my Blazer to help support my slide in camper and reduce body roll. They work great. They also work great at reducing body roll without the camper. I don't run front sway bar, and don't need to with the bags in the rear.

Good info here. Noticed last night when I drove my blazer just how much body roll there was. I was in a bit of hurry on a curvy road, and I have to say don't mix braking and turning.
