I put it on around 8k miles. The suspension kit is part number PTR13-35140. It's actually the TRD kit for the FJ, but it fits nicely on the 4Runner. The problem, though, is that you'll be lucky to find it anywhere - the set is discontinued. I got it for ~$500, but if you find one these days it'll likely be on ebay for a fair bit more. Check this thread and you may find some people who bought the kit and then decided not to put it on their rig - you may be able to pick one up cheap. As far as installation, I know a couple of guys at the local 4 Wheel Parts place and they did the install for another ~$500 including alignment. It's hard to describe exactly *why*, but the ride is definitely better IMO. The biggest plus is the nose-diving that happens if you barely touch the brake pedal is gone.

Great thread OP.

Just curious, did your MPG remain the same after swapping from the stock tires to BFG KO2s?

Here’s my ‘21 ORP with stock suspension and 265/70/17’s

Love the stock size KO2's. Stock suspension.

Don't have a pic but I've got about 60k+ on my KO2's in 265. I think I'll get another 10k out of them. As long as you raise the pressure to meet your vehicle weight and rotate them every 5k they have been great. If you don't run the right pressure and rotate them, they will cup and get loud.

I'm thinking KO2 265/70/17 is the right move for me as well on my new 2021 TRD ORP.

1) replace stock 15mm offset sliver wheels with new 4mm offset TRD PRO Matte Black Wheels Matte Black.

2) replace stock BridgeStone Duller tires with BFG KO2s 265/70/17 load C.

Can anyone tell me how far out of the wheel well this setup protrudes, or maybe it is still going to be sunk into the wheel well like the stock setup - the stock setup has the outside edge of the tire about and inch in from the outside edge of the rig. Does anyone run a wheel spacer kit with this setup?

My immediate needs are good freeway driving, good snow driving, ability to handle easy to moderate off-road, and looking a lot better than stock. Over time I'll be adding weight and I don't want to do suspension work until I know what I'm adding and also learn more about suspension options - there are SO many options. I love that, but a suspension do-over would be costly and probably frustrating.

I wish I could get 275/70/17 KO2 in a C load, but only E are an option and I don't need/want E. I don't want to jump to 285 KO2 without a good lift and I'm just not ready to take the plunge today but I really want to get some KO2s on there so I feel better about driving in snow in the coming weeks.

Look at my build for photos.
I didn’t take the measurements you ask about, but the setup is the same as you mentioned.

Seems like a solid plan, as I did the same thing in 2018.

It doesn’t protrude at all. The front still seems a little sunken in but KO2 tires have an aggressive sidewall so it looks decent. Some of my close colleagues thought it was lifted but I assured them it was not.

You can get away with running the popular 1.25’ spacers but might have to trim the front bumper and tuck a bit with possible rubbing in full lock. Or maybe not YMMV. My biggest concern was having the dealership techs over-torque them while the 4runner was under the free oil change schedule. I always carry a torque wrench with me but freedom of mind trumped the minor aesthetic for the time being.

I think you’re pretty spot on with what to expect from this setup. As for lifts, no matter how affordable the suspension parts are (spring/ strut combo) you have to factor in time and alignment so you’re right: it is costly however you look at it. You’re better off enjoying the stock setup while you can; make sure there are no drivetrain issues with your brand new truck, despite Toyota 4runners having a pretty solid track record.

I went through the same process and have no regrets. The lack of C load 275 KO2 (at the time) and the slightly bigger diameter, exacerbating the look of the stock forward rake, ruled out the size-up for me.

Moving to bigger tires now but anticipating a slew of adjustments (trimming etc.) due to the more aggressive offset aftermarket wheels. I will always appreciate the carefree miles I had with a 265/70 setup. A good tire makes all the difference.

Thanks Snowtrooper! Really appreciate all the input to my longwinded newb post.

Thanks Saker, that pic angle is exactly what I was looking for!

I pulled the trigger on 265/70/17 KO2 C upgrade last week, along with replacing the silver wheels. Thanks again for the guidance guys. Very happy with them so far.

Rotate them in the proper way every 5K and they will last. I've got 65k or so on mine now and just starting to think about replacing soon. I'm sure it will take me another 5k to get off my lazy butt and do it.
