Bump Stops.. Need help

Im trying to install some bump stops on my taco. I have a few questions. they are 2.0 fox 4" stops.
1st) does it matter if the bump stop is compressed while the truck is static

2nd) Is it necessary to utilize all of the bump stop -- meaning removing the original poly stoppers (obviously its going to be better, but thats not what im asking). So is it a progressive dampening system? Does the last little remainder of the bump stop make the difference or having a poly stopper before the hydraulic bump stop maxes out.

Details on why would be awesome. Im looking to maximize the bump stop. THanks

 

whoa, where are you going to mount air bumps? front/ rear?

these things dont just mount up and your good to go...

 

haha, this was way more advanced than the title suggested.

 

im planning to mount them myself. A lot of what ive seen, people place them at static height right before the spring compress. So the stop is just touching the arm at static.

as far as the 2" vs 4". ive seen plenty of people using 4" in the front.

So do any of you know if this is a progressive dampening system?
Meaning they get harder to compress the further the compress, and is the rebound to strenuous for them to be compressed at riding height.

 

*waiting for mike to respond*

 

depending on where you mount the stopper is where its going to kick in, further out near the wheel or near the joint of the arm... but i talked to some people and riding on them is fine. So if the stop is compressed while stack its fine it will just be kinda of stiff. and the stoppers are not progressive. So using 2" of a 4" bump stop is the same as using all the travel on a 2" bump stop..
Thanks for the info fellers
