I'm glad to see that there are so many people that are running IFS suspensions and doing really good on the trails. I can't wait till I can get back to the trails. It's been far to long since I have been out.

 

I'll see if I can find my pics

 

still working on getting up that hill in ym sandrail.

 

I've only ever made it to the top in a YFZ450.

I've pulled a lot of buddies out backwards on the hill too.

 

And here is a pic from FJ in AZ. The first pic is Chivo in Tucson.

 

I want to play again. These two are form today.

 

The thing I like about this picture is how it really shows the strength of IFS. Yeah, sure that Jeep would ultimately get more flex going - but it's cool how the IFS keeps the tires nice and square to the ground with the treads firmly planted on the ground. The Jeep in comparison looks a lot less stable and like it would have a lot less grip......

 

some driveway flex shots.


I might have to do some trimming so i can tuck those wheels a little more. But i was thinking of going down to a 31x10.5 tire since i don't see the trail very much, and save the bigger tires for off road only.

 

Semi-poser I suppose......was up in the woods and came across a water tank and these slabs. Couldn't really come across anything else in the trails surrounding...oh well.

 

Two new ones from today:

 

This is my Bro's stock 4Runner flexing a little bit. Theirs still more he can go.

 

i'll play...

i was driving along one day... then BAM! the ground opens up and well...




for "action" footage... cue up around to the 50 second mark: (17 meg video file)

 

Here are some from Death Valley

 

Does this count???

 

i was seriously thinking about doing that!!! you beat me!

 

That is some rediculous flex from an IFS. I guess you really do have a monster of an IFS setup on your truck. I would love to have that same setup under my rig, but I can only imagine how long it took you to find everything and then have it tuned it right.

Is that something that someone could do easily now that you know what you are doing and could walk said person threw it?

 

Not to knock his setup, but Look at the cv angle on the passenger side. YOWZA!

Also, I'm willing to bet that he had the torsion bar removed (or completely uncranked) to allow for that much compression. If it were under load, the truck would be leaning off of the jack stands.

 

I would really want to mess with my IFS that much for the trails that I run on a normal basis. I would much rather save that money and do a SFA on my truck. I'm just going to put the t-bars at stock, add a bj spacer, and some nice rear springs. I figure that will get me everywhere I'm happy going with my truck till I want some more.

 

flex? IFS? thats possible? HAHA

seriously...



My truck does really well out there in the thick of the woods but most of that is due to driving it right and a TrueTrac in the rear. The Front just won't flex enough and having the stock position on my rear shocks (with shorter than needed rear shocks) I don't get the flex out of my rear end I should.

Toyota OEM mistake #1, mounting a shock behind the rear axle. Doh, really.. it doesnt do any good having them opposite each other and having the shock behind the axle limits the down travel! Shock has to extend further to have the same down travel as if it were infront of the axle. (ie, its further from the spring pivot point)

I have BJ's and aftermarket torsion bars and I've found the limits of the stock IFS. You can only have the arms drop so far before you experience axle binding. Infact, with stock upper bumpstops with BJ's (1.5") the axle binds. So I had to fab in larger upper bumpstops to limit the down travel.. Almost making the BJ's pointless. Though the truck sits higher, it doesnt flex ANY better.

*as you can see in the upper picture, my front end barely budges at all and thats a lot of weight on the front suspension. Torsion bars are hardly cranked past stock height. Just enough to match the rear extended shackles (which were the biggest improvement to the suspensions thus far)

 

The reason you don't get any flex in a situation as shown above is that there is no weight over that tire. This gives it no reason to compress. A functional IFS system will flex well when crossed up or decending an obstacle (More weight over the compressed tire).

This type of situation is the downside to IFS flex. A solid axle clearly wins in that scenario.
