What bump stops are you running?

[timbren-industries]

Oh yeah the stock rears are terrible to say the least!

For sure, any info is valuable.

I am particularly interested in the how the Lexus deals with a mild ~2-3" lift as it looks like it has a "cage" for and aft and the Timbren says nothing about performance and added height. While I don't think it matters that much most of my curiosity is how square they come in contact with the rear dif during compression.

Our bump stops are designed to hit square and reduce the impact of the bump. Let us know if you have any other questions!

I bet some photos of your 4Runner products would be greatly appreciated. If you have a side by side with OEM I think that would give everyone some good perspective also

Installed Energy Suspension bump stops in front, and DuroBumps in the back. Didn't get to test it off road yet, just regular driving. Honestly, I'm not sure I notice anything different during regular driving. The front bump stops have about ¼inch to ¾inch of a gap between the stop and the lower control arm. Pretty sure I've hit it a few times already. I think I feel like the the ride in front is smoother when going over bumps. I have to try it off road, and see how it is when flexing, and on drop offs.

I just got the rears today, so haven't driven with the DuroBumps in the rear yet. I'm sure it'll be similar, and won't notice any difference in ride during regular driving. I can confirm that the DuroBumps DBR35 that are listed and described as 1.5inch are actually 3.5inch for 0 - 2inch rear lift which makes sense being that the stock rear stops are around 2.5inch. Wouldn't make any sense if they were shorter than stock. The DuroBumps being rubber are a lot softer than the Energy Suspension flex polyurathane stops. I'm hoping the Energy Suspension stops up front won't take away any up travel.

I installed the energy suspension bump stops in the front a few days ago. Only able to do street testing for now, but I did take some sections of the road at a speed that I knew would cause contact between the bump stops and LCAs and things felt relatively normal, no harsh bottom out like I would have expected with the OE stops. Feels more stable taking turns now as well.

that fine but insta' fluff and what [MENTION=98117]comtn4x4[/MENTION] 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 )

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.

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.

Wheeler's SuperBumps up front and ICON hydraulic bump stops in the rear (in coil setup).

Pros:
Superbumps: decent price, works great at softening harsh impacts

ICON: works great at softening harsh impacts or when carrying heavy loads over bumps, adjustable height

Cons:
Superbumps: large enough to almost always be on contact at stock or mild lift. I'd prefer something shorter to allow the suspension to do it's job

ICON: $$$, location in the rear coil is not ideal.

pics 1&2 are front superbumps. Pic 3 is ICON hydro bump vs stock bump stop. Pic 4 is ICON hydro bump installed

If you had to do it all over again, would you still buy the icon hydrobumps for the rear?

For my main off-road use (high speed /off-road in the desert): Yes. Especially for a heavy rear end with bumper/ tire carrier where the vehicle bottoms-out harshly with bumps.

For anyone who mainly off-roads other than this (i.e. trail use, overland driving, crawling) it's not worth the added cost.

You sold me on dem hydrobumps...:guitar3:

going to run them in conjunction with the timbrens.

thanks for the advice broski.

GREASE BUMPS BABY

Lol I got the email for the thread update (didn’t have the image) and I was like hyrdobumps, someone’s making a water filled bump stop, the fq is dat.

Could you image the wintertime calamity if you had frozen solid bumps stops
