Determining Your Factory Control Arm Type

IMPORTANT: GM (Chevrolet & GMC) produced several knuckle/control arm configurations in 2014-2018 model trucks.  When purchasing certain suspension lift kits, you must first verify your vehicle's knuckle/control arm configuration.

For BDS kits requiring factory control arm selection: 

  • Cast Steel control arm equipped models will require the "Cast Steel Control Arm" kit.
  • Stamped Steel and Aluminum control arm equipped models will require the "Aluminum Control Arm" kit.
Be sure to verify which factory control arms your truck has before ordering by referencing the help images below.
