2011-2018 Duramax Upper Control Arm for 4" Kit (67-3411)

Fits

Lift the front of your Duramax up to 3.5" with these HD Tubular steel Upper Control Arms with forged torsion keys to adjust the lift height without compromising the factory ride. All components of this kit give your truck a well-deserved upgrade that won't break the bank and are incredibly stronger than OEM units. CNC Machined differential drop spacers lower the differential and put CV axles at a safe factory angle on 4WD trucks as 2WD trucks don't use these spacers.
