Specific tire / lift question

[omegadeluz77]

I have a 2016 SR5 and am looking to installing bilstein 5100 (2.5 on front) all around and a daystar 1.5 rear spacer. I will put p285/70/r17 Cooper a/t3's on stock SR5 wheels. I wanted to inquire with anyone running this set up if they had any issues with control arms rubbing or getting alignment within spec. Thanks in advance.

What's the question?

btw, every 285 fits different.

A lot of views with no replies, basically you may or may not need UCA's. More likely it'll drive pretty poorly if you don't. With the heavier 285 (assuming the shop will mount on the wheel since it's not to spec) you likely will hate driving it on the highway without new UCA's as you won't have enough caster. You may also have even more rubbing issues as well for the same reason. Every truck will be a little different...

Not sure if you reviewed this yet?

I had stock UCA's with my current lift for almost a year with 265's, it was barely in spec and twitchy in the highway. That was with a lighter tire, I don't think I would have been able to stand the Duratracs without the UCA's and better alignment.

Should work fine and alignment should go into spec.

It still might be a little twitchy with stock UCAs, but it mainly depends on the individual truck and the alignment shop.

You may also need to trim a little plastic or push the plastic fender liner forward to avoid some very minor rubbing.

I have 5100's set at 2.5" and Daystar 1.5" spacers in the rear. 17x8 ET0 wheels w/ 285/70/17 ATP. Yes, these rubbed badly. Initially after the install the truck would wander all over the highway. My alignment tech got the caster to 2.5. So far it has been driving great. Stays straight on the highway going 70mph, heck, I can let go of my hands for a little bit! Steering wheel doesn't veer left/right under hard braking either.

I trimmed off good amounts off my fender lining and shaved down the bottom edges of my bumper. Still rubs at full lock while flexing on uneven surfaces. I am using stock UCAs. The tires have never rubbed against them even when "wheeling" offroad.

Hmm, seems I may just do the 1.75 front setting, 1 inch rear spacer and change to 275s or stock tires. This is my wife's DD and she'll flip if driveability is severely impacted.:doh: It also seems mounting 285s on stock 7" SR5 wheels is not recommended.

Will the 1.5 Daystar rear and 1.75 front setting cause greater than factory rake?

No.

The rake is there to handle different loading. Think about it: A 4Runner can haul a bunch of gear and a trailer. It actually is level stock with 500 lbs in there. So if you level it with no weight what will happen when you have two fat people in the back+ all their gear? Your headlights will be in the trees lol.

Lol, yeah mine seems pretty level with factory suspension. Maybe due to the 3rd row.

Will setting the front 5100 shock at 1.75 improve alignment settings?

No. If your alignment is within OEM spec (regardless of where in the range it is) it is good. That's why there is a "range" in alignment specs. Stock height will give you the most adjustment. If you want to lift and have the same adjustment as stock then you need new aftermarket UCA's. Just remember that your 4Runner, in it's stock configuration, is at it's most reliable and maintenance free condition. If you add aftermarket components to "improve" looks, off road, etc then you will change that metric.

Got my 5100's installed yesterday. No rubbing so far on pavement and tracks well on the highway. [emoji4] Thanks to all for your advice.[emoji106]
