Hard on ball joints and cv shafts. Dont forget to get headlights aligned after you crooked your truck. I imagine you dont do much country road stuff,so its not as bad for front end wear.
I'm just getting 35s (currently have 32s) a 2.5in leveling kit and 1.5in wheel spacers. Shouldn't be to hard on my cv shafts or ball joints with just a leveling kit. I used to run 4-6in lifts on my Jeeps with 35s on one jeep and 37s on the other. 40k miles between the 2 Jeeps in 2 years, and I beat the chit out of them. Took them rock crawling all over Southern Nevada and Southern Utah.
