How much rubbing can I expect if I get 20x9 -12 offset wheels and 275/60R20 tires? I have 5100 upfront set on the highest setting.

Worked on my dads truck this weekend, here it is completed:

2016 Silverado LTZ Z71 (Cast Steel control arms)

2” Rough Country leveling kit 

2” Lift block and U bolts out back

295/55r20 Nitto Ridge Grapplers

Factory Snowflake wheels

Bora 1.25” spacers all around

 

I need to clean it up and get better pictures.

.. just for anyone concerned about mileage impact from leveling with oem tires..I have put around 500km since level with zero negative impact to my fuel mileage.

Hmm, what kind of driving is that? 2 inches higher in the air will impact highway mpg. I did a test with and without the air dam at 75 mph over a 30 mile loop and lost 1.3 mpg. Even having the air dam on more air is hitting the axle, control arms and anything else hanging lower now being higher 2 inches in front. I can see mostly city not having an impact but not highway.

75% of my daily driving is 110-130kph (or around 70-80 mph).. to date I've put around 4000 km on truck since installing the struts

You generally ALLWAYS see mpg loss on all leveled truck due to the change of wheel and tires usually because of being wider or heavier and not totally due to a 2” height difference

On the passenger side while in reverse, we had some light rubbing on the little rear corner plastic.  I just pulled it off and trimmed it down where it was rubbing, and its all good now.  It's the perfect stance IMO.

 

A huge plus is that before the spacers, the 295 tires were rubbing on the sway bar at full lock in both directions.  The Bora spacers completely took care of that, and now 0 rubbing issues.

What size spacers did you use? I am running 285x60R20 Toyo Open Country RTs and I used RC 1/2 inch spacers on mine to eliminate the same issue.

.. the 1.25" rear lift kit  I ordered for the truck came today.. went with a company that I thought had a rep for quality - Skyjacker - only to be disappointed when the lift block kit arrived to find a short block that they wanted to be stacked underneath the oem block.. what a load of garbage!.. seems I just wasted my money with this company.. not looking to spit a block and ruin my truck.. especially when towing.
  Can someone please recommend a one piece small lift block of good quality..ie. iron with pinion angle correction?

Going to install a 2” level in my 2016 Double-Cab 4x4 Z71 to then add 285/65/18 or 275/70/18 tires. 

 

Looking at both the upper and lower spacers, what is the conscience on which is the better option? The upper coil spacer or the lower strut mount spacer?

I’ve referenced this thread a lot over the years for multiple trucks so thought I’d come back and give something back when I had the chance:

 

I had Bilstein 5100s at highest setting and ReadyLift rear +1”s installed 2 years ago by GM dealer. Angles seem fine. There was a point early on where I thought I was feeling some new slight vibrations, but I tend to be overly paranoid about stuff and all has been totally good for about 20,000.

 

Finally pulled the trigger this weekend on Duratrac 275/60R20s. They fill up the wheel wells a LITTLE more than I anticipated, but fortunately I like the bigger tire look over the lifted/high clearance look anyway. 

 

No signs at all of rubbing after first 100mi. I also have gatorbacks as you can see from the pic, and those eat up some space as well. We’ll see if it’s completely rub-free after a round of towing or two-tracking. If so, zip-ties should take care of it.

Added new tires to mine yesterday.  Was running the 275/65/20 Michelins that came off our farm truck when we bought it.  Ran them into the ground and was looking for an AT.  Decided on Ironman All Country AT.. $527 delivered to my tire guy, and $30 to mount and balance the 4.  So, $557 total and they ride like a dream.  Seen nothing but great reviews on them, so we will see how they work for me!

Truck has a 2.5" level, 275/65/20 Ironman AT tires, and AMP steps.  Painting the back bumper and wrapping the front one to match, next.

Well, I spoke too soon.  Poked my head under there after lunch today and spotted UCA rub marks on the one side I could see without laying down.  I'll have to crank it to full lock and get all the way under there tonight to see how bad they're hitting...

if its not a major issue add small spacer imo. i went w the lift vs level to get the wider rim tire look i wanted.  if its only rubbing a bit on full turn?? thats minimal and youll probably work around it knowing its there. just my 2 pennies worth

.. update on my rear block lift.. I put my OEM block back in the rear today and the truck is back to level vs the rake I need in the rear for towing. I had pulled the trigger on another solid 1"lift block (2.25"block) from Readylift after searching YouTube after the crappy Skyjacker block I bought initially - problem - the block has a taper cut in it which in turn knocked out my pinion angle causing vibration. My truck rides BUTTER SMOOTH with the Eibach suspension and I won't accept any driveline vibration. This is strike 2 on the lift blocks now and honestly I don't really want to roll the dice on yet another vendor with sub par blocks. I think I'll just wait until next spring and install a set of Firestone air bags for towing and leave the truck leveled.

    • not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...
    • First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.  
    • I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou
    • Is it an optical illusion in the pic or is the truck really squatting that much horribly?
    • My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
