A few suspension questions...

[Brage]

I have a ORP without KDSS and am putting a set of 6112s on the front at ~1.2. 5160s on the rear.

1. Should I drop the sway bar or diff? Based upon research, it doesn’t sound needed.
2. I am interested in raising the back about .5 in... is a cornfed spacer my only option? Anyone make springs that would be a better upgrade while I’m in there?

I saw an Eibach 1" rear spring somplace....

Thanks... thinking if I go up 1” in the rear that I should probably go up 1.6ish in the front.. ? that would probably be about as high as I would want.

I also think corn fed will cut a rear spacer any size you want. A 1/2 inch spacer lifts one inch, just the way it works with spring compression. Depends if you like the level or raked look.

Given the reviews on those Eibach springs, that sounds like a winner. At the 1.2 or 1.6 setting, I shouldn’t need to drop the sway or diff, right?

Definitely not necessary to do a diff drop at that height. Once you get to 2-2.5 I would recommend doing though, a lot of people do a 2.5/1.5 and still don't run so you are all good.

Pretty sure there's no "multiplication factor" for rear spacer lift. The spring rests directly on the axle housing, so 1" of spacer gets you 1" of lift.

It's different in the front, where the geometry of the spring's mounting point on the LCA means you get around the 2:1 ratio you mentioned -- 1/2" of spacer gets you close to 1" of lift.

Always a good idea to read through the lift buyer's guide thread -- lots of great into there: 5th Gen 4Runner Lift Buyers Guide - Toyota 4Runner Forum - Largest 4Runner Forum

not true. back end is a 1:1 ratio. front is a arm setup so yes there is a roughly 1:2 ratio.

I have Eibach Pro truck 1" rear springs and this is how it looks. Front is lifted about 2-2.25" over stock.

I'm at 2-2.25" over stock in the front. CV angles look straight. Did not install a diff drop.

A lot of people say its unnecessary. Companies like Toytec 'push it' because its a product they manufacture and sell.

Are those 265 or 285 Wildpeaks?

265!

265!

Yeah right after I wrote that I came across a photo of someone with 285 Wildpeaks and they're noticeably way huge.

265's have done me fine. I think too many people jump into 285's because of what they see online as 'cool' versus looking for something to fit their actual needs.

Yeah, sometimes the 285s seem "just right" in photos and sometimes they look absurdly gigantic.

I've got 265 Wildpeaks on mine and with my only "lift" being a Cornfed 1" spacer, they look perfect. Just never sure how I'd feel if I went another inch taller.

Here’s what my 2.25” lift looks like with factory 265 size Falken Wildpeak AT3W tires.

Thanks for the picture, that's exactly the setup I was going to try out to replace my 6112/5160s. It looks perfect. What spring rate Kings do you have? I was probably going to stick with the 550# and I am curious how that will pair with the slightly firmer than stock 1" Eibach rear. How many threads of preload did you do in the front?

I’m using the 550 springs. I don’t remember how many threads are showing but pre and post measurements (Center of hub to fender) was 2-2.25” difference. I’m out of town but will count threads when I’m back.

550 springs are fine. I may get 600 to stiffen the front just a tad.

I’ve got 650 Lb springs and 0 preload . Just like you said I wanted stiffer a tad. But it drives sooo... smooth with stock weigh I figure leave like this . And it gave me ~ 3” of lift
