Yea, a leveling kit is a must for 35’s. Ready Lift has a good kit. I’ve heard mixed opinions on Rough Country, but it’s just as popular.No leveling kit, just the factory lift and I think because I was confused between a 2" factory lift and a 2" leveling kit is the reason I'm having so much trouble stuffing the 35" tires in there. What kind of leveling kit did you use? Maybe that's what I need to do.
