I'm running 305/55/r20 which is the same and no trimming rub a little at full lock turn up or down a driveway that's it and very little

 

 

SuperAllTerrain

Cant speak for the stamped control arms on the newer trucks since I've read different things about them. But if you go one page back 227, i just posted pics of my truck. 305/55/20's with no clearance issues whatsoever. At full lock left/right and hold, it barely ( and I mean BARELY) touches the sway bar but no UCA's. The rub is so light I can't even feel it through the steering wheel. Had to force a couple of sharp U-turns then get under the truck to check. And I also heavily contemplated the 295/55's but was very happy i went with the 305's.

Anyone help me out on tire size?

 

2016 GMC Sierra SLT

Stamped Steel Control Arms

Factory 20x9 Wheels - (23220752)

 

Installed 2.5" Rough Country Lift this weekend, with rear blocks.

 

I've read through all posts and nothing is clear, tire rubs on one truck but not the other.

 

I am looking to run Nitto Trail Grappler's 33x12.5x20 (32.76x12.52) or a Nitto Trail Grappler 295x55x20 (32.91x12.52).

 

Will either of these fit without rub, if rub, how much trimming.

 

Thanks for any and all suggestions.

I have stamped steel and my tires (305/55) rubbed with stock wheels on s Zone 4.5, OBVIOUSLY a lift is quite a bit different from just leveling. However there are other trucks with the same setup running stock wheels so I'm assuming it has something to do with the shape of the stamped steel UCAs.

Depends on the tire size and brand. Based on all my readings with a 2.5 level we should be able to run safely a 32.8" x 12.3" with no rub on oem wheels. I should be getting finally my 2.5 level this Saturday installed and plan to run later some federal 33x12.5 r20 m/t. On my stock wheels. Worse case scenerio if i get some rubbing i'll throw some 1/4" or 1/2 wheel spacers. But iam pretty confident i should be fine since the tire specs of the federals fall on the above measurements.

Just a heads up on the spacers, you can read 1000+ reviews on how good and reliable they are and i even thought about it at one point if i ever encountered rubbing. But I have 2 buddies who have ran them, one a 1/2 and the other a 1in, both couldn't stand them. Both complained about incredible wheel shake after the install, and one even had his right/front wheel literally fall off his truck while doing 68mph down the interstate.

I HAD the RC 2.5 leveling lift kit, factory wheels and tires and yes, my driver side tire did rub on the sway bar. Took it off and shipped it back to them, everything back to factory with no rub. I'm still in search of a better quality lift kit but I will not be purchasing RC stuff again. Those plastic spacer that goes under the struts, they both cracked on both sides. It's plastic! Other then that truck rides perfect but it's stock...

Were they running hub/lug centric like bora or cheap ones?

If a spacer causes vibration it's likely one of two things, either non-hubcentric or there is a small rock or debris in between one of the two mounting pads. If there are thousands of successful stories and you know of two that's a 99.998% success rate

Hello all.

 

I am somewhat new to customizing a truck as I've had my 2015 Chevy Silverado LTZ Crew Cab for just under 2 years and have only done a couple cosmetic things to it. Finding this forum has not been in the best interest of my wallet! LOL

 

After doing some extensive reading on this topic, I think I have decided to get the RC 2.5" kit but I haven't to decided if I want to keep the 2" blocks or go to 3" as I'd still like to keep some of the rake of the truck. I have also started looking into tires as mine are close to needing to be changed anyways and right now I have my eyes on the following (in the below order of preference):

  • Cooper Zeon LTZ All-Season Tire - 275/60R20
  • Cooper Zeon LTZ All-Season Tire - 285/50R20
  • Nitto Terra Grappler G2 Tire 285/50R20
  • Cooper DiscovererHT Plus Tire 285/50R20

They will continue to be on my stock 20" in rims as cash flow isn't enough yet to get other rims.

 

Please let me know if I am on the right track or any concerns you see with what I am proposing. Thanks for everyone's insight and help.

Question for all the leveled trucks with 4x4. Have you guys dropped the differential to alleviate cv angles and avoid some premature wear. Or if not then how many miles have you put on your rig with no diff spacers.

I'm in the middle of installing motofab 2.5" upper strut kit. I have the spacer on but after turning the strut assembly 180° to remount it the angle on the bottom strut is way off from the lower arm. Can I do the other side and just switch strut from driver to passenger side?

    • Shock and spring rates are specific to the NHT max tow package.  Changing them will alter the performance of the suspension.   Not even the factory GM Trail Boss 2 in lift is compatible with NHT trucks as well.  
    • Thanks, all. It sounds like keeping the software "as is" is the best course of action.
    • https://en.wikipedia.org/wiki/Overengineering   Excerpt from the above link: (BTW the above is a 90 second read)   [Quote]   A story about very precise engineering is given in the 1858 story The Deacon's Masterpiece or, the Wonderful "One-hoss Shay": A Logical Story by Oliver Wendell Holmes Sr., which tells of a carriage (one-horse shay) Because it had been engineered so that no single piece failed first – no piece was over-engineered relative to the others, and they thus all collapsed at the same time. A similar quote by Ferdinand Porsche claimed "the perfect race car crosses the finish line in first place and immediately falls into pieces."[5]   [End Quote}   By Engineering's  own definition then; the AFM and Torque Converters, 4-5-6 clutch assembly of the 6L80E, and a dozen other common chronic parts and systems failures are "UNDER ENGINEERED".

    • I was in Utah this week attempting a bow hunt in the Wasatch mountains with friends.  On the evening of the first hunt, making my way across a ridge to a friends camp, the upper control arm on the driver's side separated, the CV axle got trashed, and the wheel was dang near at a 45 degree angle to the ground.  I was able to get it towed off the mountain and into town about 3:00 am, and spent the remainder of the night in an O'Reilly's parking lot.  Luckily, there was a Chevrolet dealership not to far away so I was able to get to the dealership and pick up a new CV and UCA.  It would have been a few days before they could have gotten to the truck and I brought tools with me on hunt since it was a two day drive to get there, so I did the repairs myself in the O'Reilly's parking lot.      What's interesting is that the UCA ball joint didn't break, it just popped out of the bottom of the UCA.  There was VERY LITTLE evidence of grease on the ball joint or in the socket, and you could see where the ball joint had warbled out part of the socket over time.  I guess that's what happens over 186K miles of use :)   Big Kudos to O'Reilly's for letting me work on the truck in their parking lot.  However, they made a $150+ off of me from the purchase of various tools, so I guess it was in their best interest anyways :)   Getting towed off the mountain.   UCA Ball Joint Socket   Trashed CV   Suspension disconnected and UCA and CV Removed   New UCA and CV installed with the suspension buttoned up.
