Is it possible to install a leveling kit (torsion keys and rear shock extenders) with a Z55 suspension? I put a set of P285/65/18's on my 2006 Yukon Denali and they're rubbing a bit when fully turned on inclines and declines. If I installed a leveling kit, would the ride height sensors adjust to it? Or is cutting out the wheel wells and part of the running boards my best option?
