It's funny you mention that because I was just thinking about this on my way home in the rain today. I bought my 2018 new 27 months ago and I'm still using the OEM blades. Half a dozen times a year I'll wipe them down using a window cleaner (without alcohol or ammonia) but that's it. I never thought I'd say this but when they do go I might just buy another set. Generally I have to buy new blades every 1-1.5 years so even if they're typical GM over-priced if I only have to swap them every 3 years it might be worth it.
This afternoon I was out running some errands in my 2018 Sierra 2500HD and as I was leaving the last store it started to rain. It was spotty; sometimes it was light rain, sometimes drizzle, but certainly nothing heavy. The trip home was about 20 minutes so I wasn't on the road for any long period of time. As I'm unloading the truck I walk past the front and noticed there was fog on the inside of both headlights. It wasn't where the reflector or parking lights are but it was everywhere else so I assume the heat from the lights cleared those spots. I've had the truck a little over 2 years (bought new) and this is the first time I've seen that, although to be honest I never looked before (I didn't deliberately look this time either, it just jumped out at me). I went outside about 90 minutes after the rain stopped and there's still a little bit remaining. A few months back I swapped the HID modules for Morimoto XB HID D5S but since I'm working from home since March I haven't gone too many places at night in the rain where I would be using the headlights. It seems hard to image that has anything to do with it though. It's also hard to imagine both assemblies went bad at the same time so that seems unlikely as well. Anyone else have a similar issue with their truck?
You should consider this to be a regular maintenance item. Rancho has had problems with their adjusters freezing since the day they first released adjustable shocks, which has to be at least 15 years ago. They still haven't figured out a solution apparently.
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.
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.
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.
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.
Here's my 2018 Dmax with about 25 miles on the odo. A lot of the pictures in this thread show the paint in a darker setting so I wanted to add a few in bright sunshine to show the other side.
