88 chevota suspension mods?

Ok guys,

Just got the shop cleared enough to get my toy in. I am going to at least rebuild the back half of the frame and am thinking about doing some suspension mods at the same time. Anyone have any suggestions, 4 link, 3 link, bags, struts, springs? I am trying to figure out which way to go. I am also considering building the full frame, but I think I want to keep the independent front end, any reason not to?

The truck currently has 4 inch lift springs in the rear and a superlift 4-5 up front. The back half of the frame is weak and needs some repair. I am kinda leaning toward, starting from scratch building a whole new frame but time is also going to be an issue as it is late in the build season. What would ya'll do?

I think you would have more benefits having a front axle than linking your rear.

What is your tire size goal, and intended use for the truck?

The IFS isn't worth it, regardless...

I am currently running 33 X 12.50 for tires. Im not looking to go any bigger I just thought as long as i am going to rebuild the frame I may as well do some suspension mods. As you may have noticed by the title of the thread, this truck is no where near stock now. Pretty much the only thing stock is the frame, axle housings, control arms, and some of the cab. The list keeps getting shorter and shorter, lol. Ive had it for 12 yrs and do some work on it every few yrs.

I forgot to mention this was originaly a v6 truck so it has the bigger axles.

I like to play in the sand, climb hills and trail ride, never got into crawling. Although I want some good articulation, it will be helpfull while trail riding.

Does everyone not like the ifs because of the limited travel? or are people experiencing breakage problems?

both breakage and limited travel are problems. By putting a front axle in you can have the benefit of lockers articulation and strength. If you want a better ride for the rear look at putting 63" chevys in. they will give you plenty of travel and are really soft. I would also suggest not to tear into your pickup until you have collected most of your parts. I have made the mistake of tearing down my rig before I had anything. 2 years later it was still taking space in my garage.

LOL I know the feeling I started my 74 gto project then kinda ran out of ambition on it. sat tore down in my garage for like 2-3 yrs before i moved it out to the barn where it still sits waiting to be finished. I plan to get at that after I do the truck, I have more fun with the truck so that comes first.

I'm not to worried about having the parts unless I decide to replace the front axle, then I will need the axle first. I plan to make as many of the parts myself as I can. I have a cnc plasma cutter, lathe, mill, and welders. I am real handy at making things out of metal. The rest of the stuff I will need is pretty readily available. I have a frame table lined up, should be available in about a month. Hopefully this will be a fairly quick build, it all depends on how busy I get with powder coat work though.

How about air bags? anyone have any expierience with an air setup? good idea? bad idea? Im worried about wheel hop if I decide to go air ride.

I don't believe there's anything larger with V6 axles, excet the diff itself in the rear has a 4 pinion carrier.

The issues with the IFS:

The ring and pinion is small and weak
The CV axles are weak
You have to space down the IFS junk which hurts ground clearance and stresses the frame/components.
In general, almost no one ever wheels IFS, so no one knows what to do with it.


What motor are you running (said originaly a v6 truck and now its a 'chevota')..?

That kinda along the lines of what Im thinking about doing, if I decide to go that route.

I am running a 4.3 chevy vortec. 4l60e trans .456 gear lock in rear, chevy Xfer case i forget the model right now.

I build this truck to go out and have fun in, not rock crawling crazy fun, just cruisin through the trail and up and down the dunes. Now I am throwing a new twist on it, I will be showing it and the pc work that I am going to do on it. So I want to fancify the suspension when I rebuild the frame. I am trying to decide which way to go with this. Whatever I decide to do, I will be making as many of the parts myself as i can. I think i am capable of constructing new control arms and if I decide to go pre runner style.


???? Air bags on an off road vehicle, any expeiriences? good or bad. I dont mean the ones in the steering wheel. lol

Someone asked for a pic in another thread, here a pic.

I don't think I would go nuts on the rear suspension unless I were SASing the front too. I would not waste money on the IFS, ditched mine finally a few years ago and never look back. There is something to say for peace of mind having that straight axle up there, not to mention the cool factor. Although I never broke the ring and pinion or CV's (they are tougher than people give them credit for), I did break a lift bracket (Trailmaster lift, sheared it in half), bent up the crappy rear crossmember that Trailmaster includes, and broke a torsion bar mount off the frame (had to drive home on the bumpstop that time). That was pretty much the last straw.

Ditch the IFS and forget it!!!

I would agree, don't go too crazy. A set of good rear springs, longer than stock with a lot of leaves would be the ticket.

For the front, well, if you really want to keep IFS, then..

Not cheap or easy, but cool. Makes the front 6.5" wider, so you'd want a new rear axle.

I broke a few teeth off the ring gear in the front once and last yr I broke one of the superlift axle brackets. If i decide to keep the IFS, I will keep the front axle and cv shafts but the rest, lift kit, control arms, torsion bars, will go in the scrap pile along with the stock frame.

Thanks for that link, that is along the line of what I am thinking about. How much do they get for that kit? Im just curious, like I said I will be building all my components. I wonder why, 6.5 inches wider?

I currently have a set of 4 inch lift springs in the rear, I put those on when i did a bunch of work to the truck back in 02. You guys are saying leave that alone? I get some axle wrap now, i was thinking a 4 link setup would help cure that. Or should I just keep the springs and add ladder bars?

Too many choices.......lol. I need to make up my mind in the next couple wks so I can get started on whatever I decide. For now the spare motor is getting a badly needed kote job.

The width was sized so that you run the bigger, longer T100 halfshafts with it. It was a way to get custom cv shafts from a junkyard.
