2015 on 35's factory height

35x11.5 Nitto Ridge Grapplers. No lift, no level. Only change was swapping out my shot Ranchos for Bilstein 5100's ( and i mean shot, i was able to compress the rears completely with ease, and have zero rebound. I was going to level it, but thankfully was talked out of it by a sponser on here. I shared these on the LML FB group, but figured id post it up here for those thinking about doing it that may not have FB.

looks great.
did you not need the leveling kit for these tires and to save money or, the leveling kit affects the ride quality?

Strictly for the ride quality aspect. I was getting ready to order it but was shown that it wasnt needed, and I couldnt do a lift at the time because i A. park in a parking garage for work and B. didnt want to give up my factory wheels. Ill rock this for awhile, and should my office change to where I dont have the parking garage, Ill look into a lift at that point.

ok thanks. I have the same truck and a lot of people say it rides better with the Cognito leveling kit, and lighter wheels

Any time you crank up the torsion bars, the ride is going to diminish...the Cognito setup was what I was looking at, and it still requires turning the bars up. I cant speak for the wheels aspect as I wanted to stay with my factory wheels. I think the consensus ive seen is going with a 3-5" lift and turning it down. Gets you the height for tires, but keeps the factory ride quality.

Truck looks great! I turned the factory keys up slightly, i haul a 24ft car hauler most weekends in the summer. I only went enough turns to still be level when hooked up, so l 6 turns. Stock 18's with 285/70/18 toyo MT, i didnt rub at stock height either. i wanted to keep the stock 18s due to their load capabilities, i found the aftermarket wheels were too "light."

To add to this- same tires 35x11.5 R20 Nitto Ridge Grappler. I did crank the torsion bars 4 turns to reduce the rake of the truck. There was -0- negative affect on ride. The spring rate does not change when doing this. If kept in moderation, ride should not be affected! Either way- truck rides and drives great with the looks it should have from the factory. FYI 295/65r20 is similar in size.
