2011-2019 Duramax HD 3.5" SST Lift Kit (69-3411)

Looking to safely upgrade your suspension without it costing an arm and a leg? ReadyLift has developed this SST Lift Lit with HD UCAs and torged torsion keys with specific indexing that increases strength and maintains a smooth factory ride. Differential drop spacers keep proper alignment and geometry while never adding stress to other factory suspension components. Upgraded tie-rod assemblies replace the tired, weak factory versions that are prone to failing.
