Will not fit 2007 Classic or All Wheel Drive models
Vehicles equipped with Magnetic Ride Control will require re-calibration
If your truck is a 2017 with stamped steel upper control arms, this kit will require either aftermarket upper control arms -or- the purchase of the Aluminum factory upper control arms. The stamped steel control arms on the 2017 models are known to have issues with ball-joints becoming compromised when leveling or lifting the suspension.
To ensure proper leveling kit fitment, using a plumb bob line (for a clean vertical) to measure from the center of the wheel hub to the bottom edge of the fender at the 12 oclock position while the wheels are pointing straight forward. If this measurement is greater than 22 then the truck already has some factory or aftermarket front lift compared to a base truck. For distances measuring greater than 22 as described above, #66-3086 or #66-3085 should be modified to account for the pre-installed lift. To ensure proper front lift height and suspension geometry, install the ReadyLIFT leveling kit

the lower horseshoe spacer. Incorrectly using these kits on a truck with 22 or more distance may result in component interference and/or excessive wear.
