Looks good anyway.....

but for something free might take off your sway bar and go for a drive to see if you like that or not. Removing mine was the single best thing I have ever done. The front end rides very nice now. I guess I get a bit of lean in the corners- but do not haul a slide in camper and I do not expect it to handle like a racecar. If you do like how it feels (at least in a straight line) hitting bumps and have an extra $120 or so you can get a sway bar relocation kit. It will level out your bar and allow it to move when hitting a bump. In the stock location when you hit a bump the sway bar is trying to compress- and it fights it.

Also what type of shocks did you get? Something like a rancho 5000? That might be a large part of it also. I put those on a K5 I had a long time ago and hated the way it rode. Since then I've been using Bilsteins. Either the classic blue/yellow for stock height and the 5100/5125s for lifted. I have been very impressed with them.

It sure looks nice though. I've heard that about RC lifts, but usually on the 6in and bigger kits. I wouldn't think a 4in should be that rough.

Look at the rear shackle of the front springs and see if it looks like it is close to contacting the frame. When I had a 4" lift mine was contacting and made it ride rough.

And to fix it did you install the off road design HD front spring shackles that are 1/2" longer?

The link you've provided says the shackles provide an inch of lift...i dont want any additional lift though....just a better ride.

I ended up buying used 6" Superlift front springs that had Offroad Design HD shackles, which are a little longer than stock...

No I bought a 4wheeler a couple weeks ago and been helping my brother-in-law on his farm. Getting geared up for a coyote hunt this weekend, I'll start a thread in the Great Outdoors section about it, cant wait!

Very strange- I do not understand what happened. I didn't put in a link. Besides the ones in that link are for a Jeep.

But from what I read starting in '87 GM had 1/2" longer front shackles even from the factory. I bought the off road design HD shackles that are the same length as the '87-'91. The longer length helps to keep the spring eye from hitting the frame. They wouldn't really provide any more lift. Maybe possibly 0.1"?

The forum has a tendency to automagically insert advertisement links into posts. I bitched about this before but was overruled. Maybe management can now see what kind of confusion it creates and will disable it. I consider it spam.

And a 1" longer shackle yields 0.5" lift.

RC hydro's are the shocks I have.

Any benefit to flipping the shock upside down??? Ive seen some do that...

That would likely hurt performance, depending on the shock's valving.

Yeah, I don't think I'd do that. That sounds like one of those issues similar to installing a glass pack backwards. You're going to get a different affect, but doesn't mean the performance is going to be better.

Alright maybe dumb question but what is upside down with front and rear shocks on a squarebody??? With my bilsteins thy said install em with the bilstein label so you can read it right side up. I have my shocks with the tube end up front and rear. I've seen em both ways, some tube end up and some tube end down???
