that fine but insta' fluff and what @comtn4x4 is asking, at least in my mind are a little different.

I checked their feed and saw a couple of Toyotas, not much in the way of actual suspension snaps (seriously like >5% of the posts are and that's it) but more like poser/ing truck porn that you see everywhere ad nauseam and one good example of 4th gen "2-bolt install". The more specific product/model info is in line with what people that actually research products prefer to see

Just cus joe on the 'gram uses it doesn't really mean a thing to the "other 50%" you usually have to know if joe races trucks or is just some "influencer" getting free products for promos.

Thanks for the response! Forgive me if this seems like a silly question, so is there a good average distance you should have from the bottom of the stop to the top of the dif? I mean, there must be an optimal distance. It seems that too much or too little distance and you don't get the full "active" benefit, right? Understanding of course that there other factors involved but most of this generation truck lifts range from 0-3" so using those as baseline is pretty acceptable IMO, only outliers are lifting in the +4" range.

Like this FJ has what looks like a 2" spacer, of course we have no idea what lift they are running apart from the fact they stuffed 37's on it (outlier

Feels more stable taking turns now as well.

I took it on a few quick off road sessions over the past weekend, and it does feel like the compressions are more controlled now. There's a section of drop off that used to feel more sudden, where now even though I went over a lot quicker than I usually do felt more squishy/controlled.

I'm trying to understand if this is a job that a better suspension could be doing. Wouldn't better suspension be able to give the same feel of a controlled stop ? is adding progressive bump stops a way to get the feeling of a better suspension ?

Anyone looking for a pair of toyota rears?

I ordered 2 of one side by mistake. Since I needed the other side still, I ordered 2 so I'd have matching sets.

Here is a good side by side you were looking for!

These are great questions! Roughly there is 4-6 inches between the bottom of the stop to the top of the dif. Where the active comes in is when it begins to squish, taking strain off the springs and dampening the bump. Our bumps have enough flex in them to go almost flat. OEM bumps have no squish and are much higher putting more strain on your suspension and spring setup. Does this give you the answers to your questions?

Thanks for the picture and your replies. I think this will really help everyone make good decisions.
Can you speak to "extended" bump stops? There are lots of opinions on this topic. Is extension a necessity? Would you consider your bump stops extended with the additional active (compression) aspect?

You can interpret an extended bump a few different ways. The sheer size of our bump stops could be considered as extended especially with how short OEM bumps are anything bigger could be considered extended. As long as they perform the way they are intended and actually make a difference then that's all you need. Ours definitely cover a large amount of space for a number of different applications and suspension setups.
