i found some energy suspension lowprofile bumpstops at autozone for only like 10 dollars now my question is are these universal and fit my 2nd gen 4runner or do you have to buy ones made specifically for my runner.

 

See the write up in the tech section here

The ones I used were "universal".

 

They are universal

 

FYI: Low profile bumpstops should increase the travel of IFS, Unfortunently this will increase the angles of the Drive Axles during flex thus making it easier for your CVs to break

 

with the cv joints possibly breaking, is there any way to add low profile bump stops and prevent the cv's from breaking? just curious

 

Hey! So that might be why both my CVs are torn! I dont have ANY bumpstops!!! :pat:

 

It would make it EASIER to break them. Just need to take it easy and not be a hammer head. Not a problem for my 3.0...

 

S.A.S. I broke 3 c.v.s in less than 5 months with a welded front end. Just be kind to the axles!

 

well, i guess if you add them (which i think im gonna do), just dont go WOT in the mud or rocks, and just pick good lines. i'm just one of the many that a SAS will not look good with my bank account, and if i can squeeze even a little extra travel out of the ifs, i will. just tread lightly

 

What makes more of a difference in front end articulation--low profile bumpstops or sway bar disconnects? Or must you do both for any real difference?

 

Disco first, lo pro second. Both help a little - but hey, it's still IFS...

 

and above all, convert to manual hubs.

 

Truer word have not been said......uhh...or typed. Your CV's will thank you

 

That was one of my earlier mods--

So I need to do both, or does it really make a difference?

 

i didnt even bother with my compression bumpstops because when generally flexing, they dont even touch. only when i hit a bump with speed do they hit.

for the extension bumpstops, i just used a hacksaw and cut the rubber down to the height i wanted.

 

so is there anything wrong with cutting all of the existing bumpstops down? or is this impossible for some reason?

 

The rubber of the factory stops are softer than the urethane of the ES lo-pro units. If you take material away, they may not do anything. Total cost of the parts for the ES Lo-Pro ones was like $21.

 

You can definitely cut down the stock bumpstops a little more than halfway before you get too close to the bolt head, I did. The shorter you make them the stiffer they'll get as there's less material to compress. I'd only cut down the 2 extension stops though, the 4 compression stops on my truck never got used except under high-speed conditions and having that extra cushion was nice because it stopped any harsh impact when the suspension bottomed out.
