2020-2025 Duramax 6" Lift Kit (44-30620)

One of the more imposing suspension upgrades you can do to these new style Duramax pick-ups is a ReadyLift 6" Lift Kit! Engineered to improve stance, performance, and capability, this kit includes everything necessary to conquer any terrain with precise suspension control and articulation, all while allowing you to run 37" tires!

Laser-cut fabricated HD steel cross-members, cast iron OE-style knuckles with perfect geometry built-in, torsion bar brackets to keep the bar in the factory location, and forged torsion keys provide just the right amount of indexing.
