I have 4” lift on 35’s but went with 18” wheel for the extra clearance. My thinking was a rock could wedge itself between wheel and other parts when off road.
4” Ready lift. BFG KO2’s (35x12.5R18) on Mickey Thompson rims. I trimmed the plastic on the rear of the wheel wells and a little off the front. I didn’t take any before measurements of the lift difference so I have nothing to compare it to. I’ll take some pictures and post.
I have a 2018 Silverado custom. Went with a 4” lift and running 35x12.5R18. Did some minor trimming and everything is good. Love the lift. No rubbing at full turns and articulation off road.
