Surely you expected crappy mileage though, right? If you increased the tire size the speedo is off so you were doing well in excess of 90 MPH. The leveling also raised the front end so now you have more air going underneath, which means more turbulence. Couple that with a vehicle as aerodynamic as a cinder block and mileage is going to be in the toilet.

You drive 2500 miles a month??? Wow, that's impressive. So too is the fact it takes you only 2.5 hours to wash and wax the truck. That's 8 hours of work for me...

That color really pops when it's waxed.

I have a 2" RC level and 285/70/18's on stock rims and there has been no issues thus far (a little over 3k miles since everything was installed). My truck is a 2018 2500HD though so it's not apples-to-apples.

I did. My post count isn't high but my time owning trucks is measured in decades so I do have some background in this area.

So far, so good. I have almost 600 miles on them now but that's all been in the dry; for whatever reason, when it's rained in NJ I've either been working from home that day or it was a weekend and I wasn't heading out. My research suggests they're good in the rain but I don't know myself yet. Looking at the number of wheel weights it seems like they might have been a challenge to balance, but they ride good. I get a little hum that starts about 40 but by 50-55 the road and wind noise drowns it out. I wish I could tell you how much of the ride difference is due to the tires and how much is the shocks but unfortunately I can't. Fox told me not to put on the front ones until I did the leveling because they would likely bottom out so tires and shocks were done at the same time. I can tell you the combination makes the truck so much more stable going over rough roads. The factory Rancho's seemed to lack sufficient damping so ruts and uneven surfaces - especially on the highway - would unsettle the truck. The suspension movements were very sharp and exaggerated. There's one patch on my commute home that really used to be a white-knuckle affair. It's a slight bend in the road with a bridge and a dip on the left side (the right side has no dip). With the original Rancho's and Michelin's the truck would become difficult to keep in the lane as you hit the expansion joints and that dip during the curve, even if you were only going 70. Now, at 75 the truck barely reacts. For me that's a huge update, there's no more WTF moment when I get to that area. One thing I do notice though is more back-and-forth wobble in the steering wheel when hitting bumps and potholes. The truck did that before but with the bigger/heavier tires and firmer shocks it's now pretty obvious. A steering stabilizer is in my future. For me that's an acceptable trade-off for what I gained.

I have a 2018 with 285-75R18's and haven't had any issue. They would likely fit your year truck as well. 285-70's would fit too. A lot of people have installed 295-70's but a large percentage of them have to trim the inner fender well a bit because they rub.

It's finally my turn to have something to post in this thread. RC 2" Leveling Kit Fox Performance 2.0 Shocks Cooper Discoverer AT3 XLT 285-75R18

Might be a bit on the high side. Figure the keys are roughly $100, add $75 for the alignment and an hour labor of $100 or so.

285/75 R18? That's the size I'm looking at for my truck. 295/70 R18 seems to rub and I don't feel like cutting into the fender liners, I'm more of a plug-n-play type of guy.

Looks like the previous owner leveled it and put on the right sized tires. Double bonus.

Got it, thanks!

Could you send me a PM with info on the LED fogs and what you did to hook them up? I'm very interested in what you did there. I don't want to go OT in the thread so that's why I think it's probably better we use PM instead.

Seems like it's mostly GM that doesn't get it, the HD trucks from other manufacturers look the part.

Are they from Kansas?
