Aight, im getting an 94 pickup, with a 3 inch sus lift. I dont know what kind cause the person i bought it from is moving and i dont think he even knows, heh. if heard it can do damage to the front of the truck, or something. im really not that smart about cars but i heard it can fuck up the front of my truck somehow. can someone tell me what the heck is going on.:confused:

Yeah it fucked the front end up on my 90, the whole damn thing fell out and I had to do a SAS!!!!!!:flipoff2:
I have never heard of any problems with a supension lift, they are great for "Posers" ain't worth a shit for wheeling.

They should not be called "Supension Lifts!" they should be called "Supension Mover Downer"!!! :eek: :usa: :cool:

is this a matter of opinion or is it a fact?

Around here it's a fact.

i know all 85s and above have ifs but what is it exactly?

can you explain to me what exactly happens to the sus lift when you combine it with the IFS? what are the problems and how they might be able to be fixed?

if done properly there are no probelms, if in doubt have someone check it over.

The main problem is that most of the components of IFS (Independent front suspension) are weaker than a solid axle. Many people do what is called a SAS (solid axle swap) meaning that they simply cut their IFS off and replace it with leaf springs and an axle. (IFS is basically everything suspension related on the front half of your truck). Anyway, I doubt youull be doing this anytime soon.

So, what you have been hearing about a suspension lift doing damage to the front end of your truck is in some ways true, but in many ways false...

When you put a suspension lift on a IFS truck, there is more stress pu on your CV joints (constant velocity). Anyway, they can break easier. But from personal experience, the main thing that breaks on IFS with lifts and big tires is steering components. This is due to the fact that making a truck with IFS steer is more complicated and involves a lot more parts than a solid axle which only need a steering box and a couple steering rods.

Anyway, when you combine a lift, with bigger tires, and harder offroad use, you will tend to get more breakage which should logical.

Anyway, you asked how you can fix this, and to me there is no way to fix this other than to do a SAS. However, this is something that you would not need to do unless you plan on doing a good bit of offraoding.

Anyway, if you want to look at some aftermarket stuff for IFS go to rockstomper.com

Good luck...

Oh yeah, if your truck has a lift and you dont plan on doing anymore offroading than an occasional trip through the mud or somehting or a trail on your hunting land, DO NOT worry about it. IFS isnt that weak.

Why don't you hang out for awhile, read some threads, and see how things work. You're asking for an instant fix for everything that could possibly go wrong with an IFS lift. Here are the problems I had:


broken drop bracket
cracked drop bracket
wasted alignment adjusting bolts
bent and twisted mounting points for the drops
rock scars on my skid plate
lack of front end travel
suspension bottoming coming off of rocks
etc. etc. etc.


Oh newbie :flipoff2: :flipoff2: :D :D

what really is the problem? Someone new to our sport has afew questions about something he knows nothing about and only afew people can answer the question serous, we want a climbing number not a desending number in our sport, and after all we all started somewhere.


NICK

Your truck should be fine for a while, it depends on how much offroading you do. If you don't do any then I wouldn't worry about it, it should be fine for street as long as it was setup properly.

If you're just getting into the sport (which it sounds like) then you're starting where most of us did. Actually most of us started with stock non-lifted IFS (aka independent front suspension) trucks, lifted those, and then went onto a solid axle. That or we sold what we had and bought trucks that already had a solid axle up front.

Basically the main difference is that you get more travel and articulation out of a solid axle than you do with IFS. As you can see in the pics above the solid axle is clearly going to be more stable and have more traction while offroading since both tires are touching the ground. Both those pics are of the same truck, before and after he swapped out his IFS for a solid axle.

It all depends on what you're going to use your truck for and if the benefits outweigh the time and money involved in doing an SAS (solid axle swap).

Good Luck with your decision.

I just bought an 86 Runner and love how it handles on the highway. The last 6 weeks I've put 5600 plus miles on getting all over the place. But I'm mountain driving and dipping down into all the off roads and logging paths I can get to. Camping everywhere but camp spots.
I put 31's on her and really havent had any problems getting around with the SA boys up and around the sierras. EXCEPT, it's just like the pictures above, no flex, no balance. But I still get there. I've been in a daily debate about my upgrade. Lift or SAS. Does a lift, or a certain lift give you any more droop or compression? I understand the physics of the SAS pushing down as the axle goes up for articulation, but not quite the IFS works.
Considering I have my '79 sitting out forsale , gutted the 4.3 and 700r, I can still pull off that axle, since I already rebuilt it, and slap it on.
I'm not looking to be a rock god, that's why I abandoned the 79 project. 4-runner fits my cargo needs, (kids) but I'm still out in the trails with alot of free time.
So yeah, who has a satisfying daily driver?
Any suggestions from experience?
Besides "keep both and make them specific function trucks"

Good. Keep it there.

There is absolutely NOTHING that can be done to lift the IFS. You can crank the T-bars, chop the bumpstops, remove the swaybar, clearance the fenders, hammer the wheelwell seam, mount 33s...and still 3 wheel it everywhere you go. However, these are free. Do not spend $1 on your IFS.

Now. Don't bring crappy gay posts back from the dead.
