should we modify the IFS bump stops?

[troyboy162]

take a look at this image...what if we chopped the bump stops down to allow the tire to come up further into the wheel well? this pic shows the bump stop just barly engaging the frame. im not sure but i would think our shocks could compress more and the A-arms, CV's could all handle more up travel. i know that means more wheel well mods but 3 more inches of usable up travel would be very helpful.

do the second gen guys do anything to theres?



look at the guy in this picture. look how much further up the wheel can travel if it has enough weight to smoosh the huge bump stop

Thats just it. The weight is there and compressing that bump more than normally.
When I was tubbing my junk.. this was the CV angle it had when the bump was just barely compressed.

I do agree, there is plenty of angle left in the CV. The question is, is there enough angle left in the BJ's so they won't bind?
Of course, we do more damage to the BJ's by accidentally taking some whoops and drooping out the suspension way too fast.

I think there is room to improve with the up travel, and I should have trimmed those down some when I was doing my tubbing.
Before trimming those bump stops, I'd drill a few 1/4"+ holes in them (think, swiss cheese) so that they will compress more easily.

Yeah, there's aftermarket low profile bumpstops available.

[troyboy162]

thanks robinhood. do you guys run into any ball joint issues? i know your suspension is quite a bit differnt but your ball joint stock angles are probably similar

i just found the energy suspention ones. they are mentioned here. http://www.off-road.com/trucks-4x4/t...ber-18641.html

the artical also makes the good point that if you go to pismo...you need real bump stops lol

so with a little more up front and some more in the back like this guy acheived:

then we are getting a pretty respectable cross up flex.

Honestly, I don't remember...it's been so long since I've had ifs now. I don't remember there being many discussions about ball joint failure, though.

Maybe SLO knows.

With 2nd gens ifs, it's the droop angles that you need to be careful of, but there's plenty of room to modify the uptravel bumpstops. By looking at the pics that Steve posted, I think you have plenty of angle left to shorten up those bumpstops.

I've got tiney itty bitty uptravel bumpstops on my 4runner and they are pretty hard ones. When I do hit them at Pismo, you do feel them. I don't hit them that often though. That being said, the added uptravel is nice and I am able to use it on the trails

[troyboy162]

ok Steve...hammer, plasma, or sawzall?

[Scuba]

Sawzall.

on my 99, I had some low profile bump stops, they helped with the up travel, got them at auto zone IIRC

I was running 33s if it matters, lol

*Keep in mind the angles you're going to start putting on your steering rack links also. Are you running a diff drop with a lift at all, there go your angles a bit more. As for your question about bumps for the 2nd gens, honestly I didn't use any and likely won't since I'm running balljoint spacers and a different set of torsion bars, even though SLO did IIRC. I'm not hardcore enough there I guess b/c usually the most I do is disconnect the sway arm links and have actually considered recently the use of limit straps front and rear after almost ejecting a coil in back. Just pick up some $20 poly's from AutoZone or Kragen and try them out.

Thought about chatting w/ Steve since he done a few of these? http://sonoransteel.com/

If you want to get really pimp, pick up a digital camera or go-pro and place it up front where you can monitor the suspension cycling. Go someplace local and play around a little. Bring tools and a spare shaft just in case.

Scuba, I wish I had your courage..35's and IFS.. You gotta goto a LT or SAS setup soon.
