NEOutdoors, did you ever find out if the 275/65/20 would work with the 2" level?

 

or does anyone else have thoughts on this? there seem to be a lot of mixed opinions.

I think it will work if your tire is less than 12" wide and 34" tall on stock wheels.

 

You are right there at that measurement.

 

275 tires vary in width wide by brand. Check the width of your tire choice and it might fit.

 

I have a 2.5" lift to fit my tires. I have very little clearance on stock wheels running 285s.

 

An aftermarket wheel would allow it to fit with no issues except pulling back the inner fender skirts.

Not the best pic but wanted to show what the 2.5 front and 1 rear level looks like with a loaded trailer. Not too much squat

Just put them on yesterday. Seems like they are good to go. I had to zip tie the liners to make them fit but other than that, they fit with he 2" level. I'll be driving it a bit over the weekend so we'll so if there are any rubbing issues but so far I haven't noticed any. It seems that as long as you stick with the stock tire width you can go up to a 34 with the 2" level.

Mind posting pics? Along with listing the tire you chose?

Thanks man! I didn't think there would be anyway to run a 275/65/20 on a 2" level without trimming or the NorCal mod.

 

Do you think anything other than factory offset/backspacing would have been a no go? Or is there a little wiggle room?

 

I'll be buying aftermarket 20's and trying to figure out if I have to stay exactly at factory specs or if I could get away with say something in the +18 range? There just isn't a lot of 20x9 options out there with exact factory offset

Wanted the "should have come from the factory this way" look. Just got a RC 2" front Level. I went with P rated 265/70-18 Firestone Destination AT's on stock wheels. The tires are the same width as stock and 1.1" taller. Rides and accelerates just like stock. So far mileage seems to be unchanged as well. Just for fun I also had the stock muffler replaced with a Flowmaster 40 which gave me the sound I wanted to go along with the new look.

Rough Country 3.5. Highest I could go and still reverse it if I want to.

Who has some GOOD pictures of your CV angles and ball joints with a 2 inch Level? The angle thread has a lot on lifts, not so much on level. Thanks

So I was excited about getting my 2.5" Rough Country leveling kit on my 2017 Chevy High Country 4x4. I put it in yesterday, the lower piece on the bottom of strut, removed the strut spring and put in the round preload spacer, and then put in the 2" blocks. No issues installing. Have my factory 20" 275/55/20 tires and ordered Open Country II Extreme 285/55/20 and will leave them on factory rims for now.

SO IT RIDES LIKE A TANK after install!!! Is this normal? Rough Country says you can keep factory shocks. It feels like there is very little give. I see on so many posts that their trucks ride so good, man I'm jealous. I tried to upload photos but it says files are to big.

 

Do y'all have any ideas why it's riding so rough?

Should I take out the preload spacer?

I'm confused, I guess, by your replies. You stated my comment made no sense. A truck is manufactured to a certain specification, including the overall length of the strut at rest, length of the lower control arm, length of the upper control arm, and height of the spindle/knuckle. Combined with steering rack and tie rods these elements all work to create steering/suspension geometry. By installing the block that lengthens the strut, pushing the lower control arm down, requiring the upper to be pulled down as well (effectively creating the suspension lift), this changes the factory steering/suspension geometry by moving the knuckle "down", and induces positive camber which must now be aligned out. To remove that positive camber in my case required that so much negative camber be induced by tightening the eccentric bolts in the upper control arms to near their maximum amount of movement. The result being, at steering lock on a level surface caused my sidewall to rub the front of my upper control arm. However later I did find that in certain circumstances during suspension action while turning that rubbing would also occur on the back edge of the wheel, probably due to sidewall roll.

 

I'd be happy to send some photos when I get back to Ohio from Utah on Sunday. But I guess I'm confused by the fact that your confused.

 

 

So, here are the photos from the rubbing at lock between my wheel/tire and Upper Control Arm. 2017 GMC Sierra Elevation, 20" stock GMC wheels, stock 275 55 20 Continental ContiTracks.

 

This is the small polished spot on the driver upper control arm after lift kit installation and realignment; passenger shows the same wear in the same place.

This very outer lip is polished all the way around the wheel on the inner side of the driver front wheel; passenger is the same.

As far as having the lift in, I did 2" MotoFab. Same overall height as the RC blocks, just CNC aluminum instead of plastic.

 

To @ChevyGuy72 - Ride felt very similar to stock. Just a tad stiffer. However, something to consider is that since these trucks have coilovers in the front, you're not going to get much deflection out of them. Those springs are designed to carry the weight of the entire front end of the truck. I noticed while reinstalling that if I applied too much jack pressure to the underside of the lower ball joint (to hold the spindle in place while I reinstalled the upper ball joint nut) it would start lifting the truck off the stands before it began compressing the springs. I have no experience with preload spacers, so I can't speak to if that is contributing to your rough ride.

 

I'd have loved to keep it lifted. As you can see, I took the blocks out and reverted to stock. I ran the lift for a week, and after encountering the rub even when I was trying actively to avoid it, I gave up and decided it wasn't for me. I loved the look, it gave it a much more aggressive stance. But I'm already in the hole enough with the cost of the alignment, I don't want to risk any severe damage to the wheels, tires or control arms.

I used the RC lower spacers to give a 2" level. I have not experienced any ride quality issues, rubbing, etc. I too have the stamped steel upper and lower arms.

    • I agree.   However, the owner's manual, suggests that a drop over full is just as bad as a drop under. (Read black and white letters only, insert no common sense.)
    • That P0700 and loss of power suggests something significant is amiss to me.   More/other codes may suggest otherwise; I would investigate those prior to spending the money to change fluid on a transmission with a bad torque converter.    The relatively sudden escalation of symptoms to me suggests that something began failing (initial shuddering experienced) and rapidly deteriorated (slipping/loss of power). Fluid condition alone wouldn't cause the sudden escalation of problems - though it might have been the cause of the deterioration up to the point of failure.
    • Stabilitrack operation is in a sense a separate/independent operation from the operation of 'traction control'. Stabilitrack is used to keep the vehicle traveling in the DIRECTION intended, it can brake independent wheels and or adjust throttle to influence the direction the vehicle is moving.   This can be illustrated by a 'fish-tailing' example. At high speeds, if the stabilitrack detects excessive yaw (the vehicle spinning like a top, it has a sensor for this), based on inputs from steering angle it determines that the vehicle is spinning out of control, and begins working to control that unintended spin. By reducing throttle input or braking specific wheels to control or prevent the spin.   The traction control works similarly using the ABS system to slow spinning wheels and thus transfer power to 'other' wheels. The goal being to achieve wheel speeds that are all in agreement with each other, the truck then assumes that since all the wheels speeds are the same no spinning is occurring. For example, launching up a wet boat ramp, there is no excessive yaw present, traction control alone can manage the wheel spin by braking spinning wheels and cutting throttle.   Stabilitrack and traction control from a hardware and software standpoint are basically one in the same, I don't remember specifically in 2004, but you couldn't get a truck with one and not the other. The switch on the dash, could turn off the traction control, but not necessarily the stabilitrack.    A confusing comment about stabilitrack vs. traction control, the same components serve both operations, but marketing could advertise them as two separate features.    The AWD system is another separate system entirely, in addition to the other two, it uses the same wheel speed inputs but can also vary the transfer case clutch application to direct some power to the front axle, working in conjunction with the traction control to bring wheel speeds together.   The power split will never be greater than 50:50, the same as 4-high. It will never direct MORE power to the front axle than the rear.
    • Not based on the new photos I'm seeing.  Car and Driver posted additional photos that shows an auto stop start button left of the steering wheel.      
    • Car and Driver is reporting wireless CarPlay WILL remain, and they posted several additional photos, including a left knee shot, but the only hard buttons there are e-brake, auto start stop, tailgate and cargo light.  Also definitely looks like High Country and ZR2 get micro fiber on the center of the console lid and the ZR2 possibly also on the seats.
