Bumpstops

[wanderer]

Again, this is one of those questions that may seem stupid but what the heck
in ordering my lift I’m specifying TeraFlex bump stops. I watched a video on them and they seem to be really really good. They have a lot of compression.
But I guess my question is how many of you really have thought about this and what have you come to conclusion wise? Is it worth it to spend 120 bucks on really good bump stops or is it throwing the money down the drain?
all thoughts please

And it occurs to me since this is the biggest limiting factor in your up travel. How do you dial that in? How do you measure how long a bump stop you’re going to need?
It seems like you could cycle through the suspension and see where you make contact and then continue to compress the bump stop, and between where you may contact in those two numbers would be the amount of up travel you would be limited to or achieve?

I take out the coils springs, with the tires and shocks on compress the axle until the tires hit the fender or the shock bottoms out, then measure the distance between the metal bump stop housing( not the foam jounce) to the axle pad where the bump stops hit… that measurement plus a 1/2” is how much bump stop that’s required…..also read through this link, it explains a lot about picking shocks……

Also…. If you’re tires hitting the fenders isn’t a concern, and you’re only worried about shocks bottoming out, then just measure the shock shaft at ride height and then measure the distance between the the jounce housing and the axle pad, if that number is at least a 1/2” less you’re good, if that measurement is more, then you add pucks to get it to a 1/2” less…..

I measured like you, and used that measurement, along with the minimum shock length to determine my bump stop height. I have a JLUR, and only added 1 1/2" of lift, so my tires hitting the fenders wasn't as much of a concern.

I'm running Rancho MT7 shocks that were on close out. If I were to swap them out for a set of Bilsteins, I could increase my up travel over an inch.
