Whiteline 20mm rear isolators sold by Energy Suspension..ever heard of them?

[fblainen11]

So, I still haven't done my lift. I was planning on doing 2.5-3" using a combination of OME, 99 talls, and Daystar spacers. But the more I think about it the more I think I want to ditch the spacers.

This leaves me with OME 880 up front and 99 talls in the rear. That means 1.5" up front on tundra 5100s and 1" in rear on 5100s. That means my front will ride higher...which I do not want. I looked around and energy suspension sells a replacement isolator for the rear that gives an additional 20mm lift, or .78" lift. That would theoretically give me just over .25" of rake.....perfect.

Does anyone have any experience with these?

...a replacement isolator...

2 questions-
1) Why do you want to ditch the spacers?
I think "replacement isolator" is a little misleading. We don't have isolators in the rear. Well, we do, but they are incorporated into the center cone bumps.
That said-
2) Do you plan on replacing those with the isolators, or adding the isolators?
Unless you're replacing the center bumps with them, the "isolator" is the same as a spacer. If you're replacing the center bumps with the isolators, it will only give you 5-10mm of "lift". Unless the isolator is made to replace the center bumps, and give 20mm lift after they're removed.

1) I want to ditch the spacers because I've heard not great things about ride quality. I would have a 1.25" top plate Daystar spacer in front with a 1.5" spacer in the rear. If I'm wrong and the spacers will ride great let me know, I've just read otherwise.
2)I didn't know that about the rear isolators. So, if I replace them, I lose the center bumps....unless I get replacement center bumps that work with those isolators. I think it is made to replace and give 20mm lift after what is there is removed since it is considered a replacement part.

Okay, so when you said you want to ditch the spacers, that meant front and rear. Now I'm tracking.
Yeah, definitely don't run spacers on the front.
If you want the height, just get the 2881 coils up front, and run the spacers in the rear.
There are a couple reasons to stay away from spacers in the front:
Top hat spacers-
These will allow your suspension to have more droop than it was designed for. That can cause your BJ's to go past where they typically can, and will do the same to your CV's. The CV's aren't likely to be affected by the added angle, but the balljoints are.
Pre-load spacers-
These can be just fine, but it depends on the coil and the size of spacer. Adding pre-load definitely causes a harsher ride in most cases.
If you're already planning to buy the 2880, but want more height, just go 2881. I just put them on my buddy's '99 with 4Runner 5100, and they ride buttery-smooth. The rate on both the 880 and the 881 is 500#, so they're pretty soft springs.
Running spacers in the rear is just fine, and won't cause a harsh ride.
I think Whiteline is using the term "replacement" very loosely, and they are just made to stack with the factory center bumps. They look to be about 20mm thick. So it's really just a 20mm "trim packer".
Hope that helps some.

I already have the 880s and the 99 talls for the rear. Already boihjt the spacers too...didn't think it through. I guess I changed my mind after reading and learning more about the downside to spacers.

I think I'm going to go with 880s and the small trim spacers in the rear. That should level things out. That or I'll look to see if there's anyone wanting to trade the taller front springs. Both sets are brand new.
