IFS cross linked air shocks trick for better front flex

[ausyota]

Wondering what people think of this idea for getting a bit more articulation out of an IFS. http://www.4x4wire.com/toyota/tech/air_shocks/

It involves using pump up air shocks on the front end and winding down the tension on the torsion bars a bit. Then linking the two shocks air lines together so when one wheel compresses the shock it tries to push the opposite wheel down forcing a bit more articulation out of the front end.

I was thinking if a simple ball valve was added then it could be closed (after parking on flat ground) to reduce body roll on road.

I cant afford to do my SAS for a while and I can probably get some shocks cheap though my work so I might give it a go.

it will still only have as much movement as the bumpstops will allow. maybe it will allow the suspension to travel faster as there is less tension by loosing the torsion bars.

Cut an inch top and bottom off your bump stops get more travel

[dumbdunce]

think about what it would do in a sidehill situation. I think not so good.

OLD.


place 1" - 1.5" spacers under the top arms to get the lift then full arc movement is retained as well. used modified commodore pump ups on the 1 i did, and combined with the spacers worked really well.

Then all you have to cure is the continual bending ofthe idler arm,


easy?

Did that, SASed it. to your IFS

OK OK enough with the IFS bashing. I hate the crappy IFS as much as anyone. Im just trying to work with what I got untill I can afford to go the whole hog with a SAS.

Not sure if I will bother doing this or not. I will price some shocks today and see what my wallet says

And yes the IFS idler arm is poo.

Has any one resolved / made a stronger idler arm. I bent 4 of them. Would have thought some one would have come up with a stronger idea. I looked at sleaving the center but the Toyota molding wont allow it as its too thin in sections.

Speaking of which you want 1. I got 1 in the shed in great (near new, 2nd hand but never fitted to my car yo can have for $60 - paid $100).

solving the idler arm problem is really easy and you use all std toyota parts, you just have to think outside the square for a change. ( i like to keep everyone guessing ).

DON`T SPEND MONEY ON IFS.the little gains yet get out jigging stuff isn`t going to make it any stronger and the extra flex or what ever still isn`t going to do sh$t.
and the more money you save is more closer to cutting the crap of

You've had your laugh, now how do you fix it. (Not that I need to, its just bugging me).

im in the same boat, cant afford $3500 for a sas, so i have to keep patching up what ive got, they must be the worlds weakest diffs, ive deatroyed 4 crown wheels and 2 cvs in two and a half years. the money ive spent i wish id just done the sas as soon as id bought it

[ausyota]

Well I have decided not to worry about stuffing round with the IFS.
Apart from maybe fitting a locker (I figure if I can get one cheap enough there are milions of IFS luxs out there I could sell it to after I SAS it and get most of my money back).

mines got air lockers front and rear, hopefully when i can afford the sas i can get some of the expense back by selling the front air locker

[ausyota]

Madness have you broken your front end bits before or after fitting the locker?
I have heard that an ARB helps stop the crownwheel+pinion from grenading due to them flexing less.
But I would imagine that a lot more stress would be on the CVs while locked.

broken 2 crown wheels with open diff and 2 with the air locker fitted, also one cv with air locker engaged

Left hand drive power steering box imported???

I have done heaps of damage to my entire front end driveline, and suspension.

Damage: Both upper control arms damaged, 2 crown wheels, 2 pinions, ripped all teeth off all centre gears, and snapped the pin securing the planetry gears. Done 2 CV's as well.

geez i thought i was destructive, good to hear im not the only one destroying them

[pegasus]

LOL, yeah, forgot to mention the 2 idler arms I have snapped, and the current one is on its way, very flexible now, hehe

hanent broken one of them yet, ive got a spare one in the shed though,

[HG]

Yep I've reached the end of the line with the IFS as well. After breaking a couple of inner axels, 2 CV's, tie rods & 3 idler arms. Thats with 4" of IFS lift, 5" out back & 35" tires, lockers front & back. I've got my Surf going into Cheezy for a solid swap with coils . by mid Oct I should be floating over the ruff stuff instead of scarin' the bejezus out of myself lifting wheels .
I can't wait.

Brian, ths is a MAJOR problem that you have pointed out and would very badly effect the way the lux/4x4 performs... for anyone else that wants to do this mod, dont take this point lightlly unless you only drive flat ground (carparks or speed humps). I have thought about this alot throught another concept and have come to this same conclusion....but the rest of my info is TOP SECRET.
