    Installed the 2.25 kit on my at4x sierra. Rides stock, perfect stance. Can't wait to hit some trails. Clears 35x12.50 with minimal trimming on 8.5" wheels with 0 offset.

    Installed it this week, looks great!!! Haven't noticed any difference in the ride so far, either. Great job, Peak! Good times ahead.
