My rear Eibachs ($125 then) work but the round contact point only hits the front half of my axle. It might not even be that big of a deal after all, maybe it was designed that way. I would love to see pictures of the axle contact print on someone who upgraded to the taller stock GX bumps stops to confirm my rambling.

same..i would have went with the lexus option as well.

These have served me well, and are still on my vehicle.

I wont buy durobumps either, even though they probably work well.

From a design/engineering aspect and quality of materials, timbrens and ES made more sense than the durobump design.

Any loss of up travel? They feel pretty firm

I haven't noticed any loss of travel, and i don't notice they are there when I hit them (unlike the stock ones).

This might be a tad too tall for the fronts but this new redesign should compress better. I remember speaking to Ryan(*James) from ES years back and they were in preproduction testing.

Someone test them out and report back.

Idk who Ryan is, but those are just the JL bumps with a universal part number, identical to the ones posted up above a while back.

Should work up front right? Looks juicy! I think it was you!
Thanks for the correction James, it's been awhile

Ok it's part of this then

Before I left, we had rate tested the JL bumps and found that they're literally the perfect rate for 4Runners.

At this rate, I will bet that ES will just reuse the same bolt-in style JL bump as previously shown and then just include a couple of bolts and call it a 5th gen 4Runner set. In that case, I'd just buy the Jeep bump set and use my existing 4Runner hardware to mount them.

Jeep set includes 4, but only 2 will be usable, as the others are not meant to be bolted in.

Hi guys!

A question about the energy suspension bump stops 8.9104 for the front

I want to put them on, but unsure what there fully compressed at max force height is? Do they compress taller or shorter then stock bump stops? I do some fast off-roading, I'm looking for a little more comfort but want to make sure the bump stops engage the full stop at the same height as stock.

TIA
