travel is fine but the most off roading i do any more are rutted up field roads going to hunt not really beating it up .

i have the same truck but short bed with a 3 in superlift with the bilstien option worked just fine rides fine also . its on page 26 of the leveled thread with info. When i had the stock 275/60 20s tires and rims on it before alignment i did notice the tires were real close to the uca so if you want to go too much wider you will need a spacer or different offset wheel. Towing capacity im sure will suffer slightly . the max i tow is a 20 ft bass boat and since my 2017 gmc had a 7 in lift on it with a 5.3 and towed the boat just fine. i went with superlift because you can return it to stock which i will before trade in.

thanks. feels pretty much like stock the only thing i notice is the stiffer e rated tires.

my 6.2 max tow slt with 3 in. superlift . lifted actually only 2.75 with 305 /55/ 20 cooper st maxxx tires 33.4 x 12.5 . Hostile rims 20x9 +10 but needed a 5 mm spacer to clear caliper making them basically a +5. bracket removal and trimming of mud flap now has no rub .

i went to a 3 in lift with a 305 55 20. the tires i picked run larger the some others at 33.4 x 12.5 took some trimming with a +5 offset wheel but now only rubs full lock in reverse on pass side. if i would have went with the same tire in a nitto ridge grappler i would have possibly not even had to trim since they run just at 33 x 12

my sierra slt came with 275 60 20s i believe offset is 28.

Gave her a 3in. superlift and some new shoes. Still needs window tinted.

great looking truck. do you think you could have got a 295 60 r20 on it or is it tight with the 285s ?

My 14 silvy just hit 1500 miles and my goofy acting trans has cleared up mostly but it does vibrate. My vibration shows no pattern it may do it when I let off the gas or at cruise you never know when it will do it. It does it in v8 and v4 mode the truck feels like its hitting rumble strips as some have stated. Though on mine it's not really not what I would call a horrible vibration more a minor annoyance like worn out rumble strips. It does remind me of a 51 Chevy 5 window I had that shucked the pinion. It also started out as the occasional rumble strip feel but what really happened was the pinion nut backed out just slightly. This allowed it to walk when there wasn't a load on it creating a vibe. Has anyone had theirs checked for this. My intial thought was auto lock diff chatter but since I'm getting no noise along with it I might have them check the nut.
