Finally did a level lift on my 2014. These reg cab trucks are famous for the nose dive front end they have. 2" level on front and also added a set of 285-55-20 Toyo AT tires. I just can't believe it is the same truck when you stand beside it. The stance now makes it look like a lot more truck!

So i put my RC 2" level kit and Toyo 295/55/20's on this weekend. Install was simple, just like on my 2011. It definitely helps to have an extra set of hands when wedging that spacer in there. 295/

Thanks. Here is one more from yesterday. Considering we're getting 8-10 inches of rain the next two days, I won't be taking any better pics soon.

Mine is finally done! After months of research I went with the RC 2.5" level kit front only, stock rear block. 20"x9" Fuel Nutz w/ +1 offset, 33x12.50x20 Toyo M/T tires. No rubbing, No trimming, yet a

If you want it to look even higher take off the air dam. now that it is level that air dam is causing more drag/resistants, but if you like the look leave it on. All looks good.

Looks good. Three inches of rake on a regular cab looks way worse than on a longer wheelbase.

I'm not trying to be an ass. But how do you know that the air dam is now causing drag/resistance? Have you seen evidence, or is this an assumption?

You're not being a ass, if you don't ask you won't learn.

 

That air dam like all car air dams are made to push air under your vehicle or push it off to the side to make less resistance on your vehicle.

After you lifted the front end of your truck the air is now pushing against the dam and not flowing under it smoothly. Basically working as a spoiler now.

Pretend you are in the water, and you need to push a long piece of wood across if the wood is touching the water, at a 110 degree angle ( like your air dam was) it's not so hard, the force would be at the top and water would go off the sides. Now move that to a 90 degree angle (where it is now) the force will be much greater and not as controlled.

I understand the logic but that's assuming the only factor at play is the angle/height of the dam. This is ignoring all of the non-aerodynamic pieces hanging below the vehicle. Take your example and place things that create drag behind that piece of wood and even if the wood is moved up or at a different angle it will help in reducing the drag created by that in which is behind it. I appreciate your time and response. And hope this can be a constructive conversation.

 

I am a mechanical engineer in the aerospace industry so I've dealt quite a bit with drag and the likes. I've just always assumed that the dam on a truck would be beneficial regardless of height and angle (unless you are lifted high). I am leveled with the dam on and am curious now if I would see and change if I removed it. I believe that I would. My thoughts on this, are that the dam will still push air to the sides and lower towards the ground away from the drag behind it. As well as routing the air around the tires towards the outside, which believe it or not, are huge sources of drag.

Yes, but you are forgetting that the wind will be pushing the air dam back (it has some give on the sides from being so long)

 

also the rubber skid plate, it's angled to avoid wind from hitting your axle and other low hanging objects. I currently have mine off (going to be painting it) so don't think I'm strange for having it off, I didn't go under my truck to make a point lol.

If anyone here can drive so consistently that they can actually tell how much the air dam affects their mpg, my hat is off to you. Until then, all we can do is assume it works to reduce drag on stock vehicles because GM has it on there and it may or may not on leveled/lifted vehicles. But if you're already leveled/lifted, do you really give a flying hoot about a 1/4 of an mpg over the looks? So do whatever you think looks better.

 

I mean, I get it, it's fun to debate how the air dam affects it. But without a carefully controlled environment you're not going to get an answer. So you're pretty much just bloviating.

I agree that a 1/4 mpg isn't much. It's been stated that the difference is a 1/2 mpg, but that isn't really the point of the conversation. It's definitely more of friendly discussion. However, saying we just have to assume it's there because of mileage is not necessarily true. In an industry, world for that matter, where designs are driven by the mighty dollar an extra piece of plastic wouldn't be added for no reason. There is a gm published video showing the results of the dam and it's quite amazing. This is definitely included on the vehicle to help meet the demands of the federal gov for mileage.

Like you, I think the 285s look "OK" on these trucks, but not great. The more I look at this setup, the more I like it.

 

Can I get some more pictures? I'm especially interested in some pictures of someone holding the steering at full lock, and seeing the clearance around the tire (front, rear, UCA and Swaybar).

 

Finally got around to snapping these pics. Its tough to really get a good angle at it, but there is zero rub. I have about a 1/2" of clearance. It seems like now that the GM wheel wells are a tad more boxy than earlier models, we also have a bit more room to hit bumps while turning/in reverse also. My driveway is pretty steep, and when backing out at an angle, I still dont rub at full lock. That being said, Im pretty confident in saying I found the absolute limit as far as tire size goes for just a 2" level and stock wheels.

Thanks for pics. That's certainly a tight fit. Did you see any rubbing on the UCA or Swaybar? Those tires don't have wildly aggressive sidewalls, so any rubbing there might not be that noticeable in lock-to-lock turning.

 

Can you take true mounted measurements of the height (vertical and horizontal) as well as the tread width and section width (eye balled)? I'd like to compare your measurements to the Nittos I'm running now.

Hello, new to this forum but have been a lurker for a while.

Thought I'd post my setup for reference:

2017 Silverado 1500 LT Z71

Just put a motofab 2" level kit and Falken Wlidpeak A/T3 in 275/70/18 on stock 18" rims.

I do have rubbing on upper control arms at full lock. Tires at 40psi.

 

Thanks!

For those who've done their own leveling kit:

 

I've done several on my previous vehicles, and a fair amount of front end work in college, but.... I attempted to pop the upper ball joint this week, on my new Silverado, and it wouldn't budge. I used a pair of 3# hammers (one one the left side of the knuckle, the other swung from the right, and vis-versa.) Nothing! Puppy is holding fast!

 

A friend suggested that the knub on the back side of the knuckle was the appropriate target point... what's your experience?

Yeah, that was a complete b**ch. I alternated smacking front back and that nub on the frame-side with an engineering hammer until my arms were on fire. I ended up running the nut up super tight a few times then hammering. Seemed to work a little better.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL

      Tire pressure for 37s

      By Chuck FB · Posted

      First off you mentioned "Toyo Says" and then gave the pressures 45/50, was this some person at the tire shop that pulled those numbers out of his head ?   Now of course I can't know your exact axle weights front and rear, however I have much the same pickup as yourself other than not knowing your starting weight as per the pounds the truck rolled out of the factory at due to the options yours did or didn't come with or what you have added beyond the extra tire weight. The correct way to know 100% where a person is at is by weighing each axle with the typical weight the vehicle is driven with and that means taking into account passengers and making sure you figure in a full tank of fuel and a little grace for whatever you may put in the bed "groceries" !    I am looking at and not that it really matters as all the tire companies use the same charts anyway, but I am looking at the comprehensive Toyo tire chart in the section that your tire falls under and I know it sounds confusing but your tire is not an LT metric tire like your factory tire but instead because its a standard inch measured tire its under a different category called an LT floatation series tire. That makes a difference as LT metric tires they don't want to see run below 35 psi at highway speed where as with the LT floatation series it can be run down to 25 psi on the highway as long as the weight on the said size of tire is agreeable with or less than that minimum 25 psi. It blows many people away that how is this physically possible, an empty truck for one thing and larger tires with the same size wheel diameter have a lot more air volume so they can carry the same weight as the smaller tire with less air pressure.    So my truck, I have the stock 275/65R20 wheels and tires and I have a bit of weight in the box with a bak flip cover and a rubber bed mat and some tools and spare gas. The front of my gas truck weighs a bit more than some trucks of the similar spec due to double batteries and alternators. However with full fuel and just me in the truck I am weighted such that I can run 40 front and 35 rear and so that is what I have done since day one.    If I base your truck at or slightly below the weight of my truck, in theory with your tires going by the tire chart you might be right around a minimum of 30 pounds front and 25 pounds rear. Of course that would hit pretty much minimum cold inflation pressure one could run with that tire size and a near empty truck. If you have access to an accurate weigh scale to do individual front and rear axle weights I would suggest you do that and make sure your topped up with fuel and whatever else in the truck before you weigh it and then you will have a great starting point to work off of and figure out what your bare minimum pressures are you can safely run. If you do much in the way of hot weather high speed driving, bumping up a bit for a safety margin is never a bad idea but just depends on what type of driving you do. I will include the Toyo chart and the floatation series sizes start on page 31. Without a doubt at these pressures I am speculating at minimum wise for your truck, it would most certainly ride very different then it did when you were using 55 lb front and rear.     https://www.toyotires.com/media/pxcjubjs/application_of_load_inflation_tables_20200723.pdf

      Towing In Loose Gravel

      By rdonarski · Posted

      This landing is worse than most. Patchy blacktop with washouts, soft gravel/sand at bottom that washes out with every heavy rain. I tell everyone to put it in 4WD. A lot of them think they can pull out their trailer in 2WD. They end up digging a hole and then putting it in 4WD.  The lake is a pristine lake and has a lot of money on it. There are several wake boats and lot of large tritoons. The people with the money don't want it improved because they don't want more traffic.    Boat Landing 1.jfif Boat Landing 2.jfif Boat Landing 3.jfif

      Tire pressure for 37s

      By PBNB · Posted

      How wide are your rims?   Toyo specs 8.5-10.0-11.0 inches. My thought would be rim might be pulling the tire inwards creating a center that is more pronounced.    I also noticed that the spec sheet says max 65psi. So you could be right lowering the pressure to ~40 psi.
