Any issues doing rear spacer on one side only?

[Tronner]

I've got a 2015 SR5. I just installed the 5100's up front set at the lowest setting with the Toytec Eibach springs which is supposed to be about 1.75" of lift in front. I've got a 1/4" top plate spacer on the driver side. So far the rear is stock (5100's going in back as well) and I have two Cornfed spacers. I asked for a 3/4" rear spacer kit. He sent me one that's about 7/8" for the driver side and one that is about 5/8" for the passenger side.

As near as I can tell with a pretty flat ground measurement with 1/2 tank of gas the passenger side is 1/2" higher than the driver side with dead level rake measured to the fenders (37" on the driver side and 37 1/2" on the passenger side)

I'd like to end up with about 1/2" rake which seems to look pretty good and hopefully even out the height from side to side a bit. I'm wondering if I put just the 7/8" spacer on the driver side rear only what would happen or if there are any issues putting one on one side only? I assume a spacer on the driver rear side will very slightly raise the driver side front a touch and the passenger side rear a small amount as well?

I guess my options are: 1. install only the 7/8" or 5/8" spacer on the driver side 2. Install both spacers as sent 3. Send the small one back and ask for one that's 1/2" smaller than the bigger one instead of 1/4".

My initial idea is to install the bigger one and put everything back together to see what happens then determine what I need on the passenger side if anything, but figured I'd see if anyone here has any experience with this?

Dude, you are putting tons of thought into this. My method is the put it on paper and look at it. In a max. and min. situations and decide how much spacer you want. ARB prescribed a 5mm spacer for my front coil coilover. So, I know you can put spacers where ever you want within reason.

I also notice that my measurements change between winter and summer. My thought is the nitrogen shock temperature increases and therefore the height increases. Heck, I cannot repeat the measurements within 1/4" on any given day.

My conclusion, I am happy with 1/2" +/- at any time of the day.

PS - Have you done your measurements with the driver's weight in the cab? And I also carry my tools and recovering gear in the rear passenger corner to offset the lean.

Yeah, I way overthink this stuff haha. I haven't done measurements with me in the car or a full tank of gas. I basically want it to look good with close to 1/2" rake on both sides and pretty close to level side-to-side most of the time. And I don't really want to go back into the front and replace the top plate spacer with a bigger spacer. I'll probably just install it as he sent them to me and see how it looks. Or just install the driver rear first and see how it looks. Doesn't seem that hard to do the rears if I want to change it for some reason.

There was a day when the measurements were very important to me. I measured it empty, loaded, me in it, family in it, etc. Then my doctor prescribed these daily pills. Today, I look and it looks close enough, I am good. (trying to be humorous)

But honestly, I have measured it every way possible and it always changes within a set range based on the conditions. And now, I go by eye only. And I can look at the truck and tell you how much gas I have in it. And I am good with it.

I want and accept level to slight rake. If your rear is obviously too high I am bothered and if I mount a trailer and rear goes below level I am bothered.

Yoga and mediation helps me reduce the stress.

I know a lot of the 4th gen 4runner guys install one 1.5" daystar spacer on the driver rear. I have not heard anyone having any ill effects doing this.

That's good to know shaneotool. I'm going to put the bigger spacer in the rear driver side, put it back together, measure, then decide what to do on the passenger side
