Important Notes

• This kit will work on new 2015-2018 GM 1500 Trucks! 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 o’clock 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 WITHOUT 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
• Some vehicles may require the use of 15-3485 1/2" front wheel spacer when using aftermarket tires on some factory wheels. The factory wheel options and difference in backspacing vary.
