1.75" 2019-2026 GMC Sierra 1500 AT4 4wd Front Leveling Kit by ReadyLift

This ReadyLift 66-3921 1.75 inch leveling kit for the GMC Sierra AT4 is a premium kit that is designed to properly function with the factory AT4 2 inch lift kit. Featured in this kit are ReadyLift heavy duty tubular upper control arms. For Trail Boss models upper control arms are a must when adding additional lift due to binding problems with the factory control arm ball joints and contact concerns with the lower strut/CV axle assembly. The included upper control arms have corrected ball joint cup angles and do not interfere with factory strut geometry and clearance.

The front end is lifted with the use of (2) aluminum strut extensions and (2) aluminum lower strut mount spacers along with all necessary hardware. These are CNC-machined 6061-T6 solid billet aluminum construction, not spot welded low grade stamped steel often found with cheaper quality kits. ReadyLIFT leveling kit systems will not affect your factory OEM ride quality or comfort level.
