Rough Country 3” leveling kit
sku#95830 has upper control arms and shocks

After you can fit 22x10 8x180 with 124 bore 

you have to trim the inside of the rear wheel well extension and the edge of the front wheel well near the engine heater plug 

Not sure if I wanted to go that extreme but definitely something to think about.  Dont want to get too high for the 5th wheel/gooseneck.

Looks awesome but can he still get under a 5th wheel/gooseneck? 

No clue as he has neither.  It is really high though

Sorry it was a Silverado 2500. I will be putting 22’s on mine however I don’t like how a little tire there is with 35’s but don’t think I can fit 37’s tires with a leveling kit so I may need to do a 4” lift. 

2020 gmc 2500 wheel info: 

The bore hole Is 124mm

The bolt pattern is 8x180

I have vision 20x10 -25 with Nittos 37”.13.50 and had to remove front fender mud flaps, do some modifications to the bracket that holds the mud flap and fendEr liner and trim the plastic under the bumper. 
 

I have been looking at rought country 3” lift kit. I might end up doing sometime this summer

Can anyone with factory ride height go and measure from bump stop to top of lower control arm. I had 295/65/20 nitto ridge grapplers put on this morning. While they had it I had them raise the front with the torsion bars. Only went up 3/4 of an inch on driver side and about an inch on passenger side as they were uneven. No rubbing as of yet but they want me to drive it let the suspension settle then come back in to raise or lower if I want then do alignment on it. I almost think I’m gonna have them lower maybe a 1/4 in as I like a tad bit of rake. But also wanna make sure I don’t eat up ride quality by having the bump stops to close to control arm. Thanks in advance

Beach I will try to look tomorrow. Only 3/4 lift from keys seems little. The one I seen at the dealership went up 2” in the front with keys only.

Sorry I wasn’t very clear. I still have factory keys. I just had them run the bolts in some to help the new rubber clear and take some of the rake out. But I think they went a little higher than I wanted. I’ve already taken some of it out. Just need to drive it tomorrow and let it settle. Then measure to make sure it’s even

Maybe you should get the new keys and have them crank it down since you only need a little to clear the rubber. Should leave you plenty of throw from the bump stop
