6.5 Inch Lift Kit | Chevy Silverado & GMC Sierra 1500 (2014-2018) 4WD | Cast Steel Control Arm | Strut Spacer & Nitro Series | Zone Offroad

Configured for trucks with Cast Steel factory control arms. Front lift is achieved via Cross Member & Strut Spacer (6.5" front lift) using the OE strut, paired with Zone Nitro rear shocks and a 5" rear lift block.

Zone Nitro shocks feature a nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, dual-welded ends, self-lubricating seals, and a gray powder coat finish.

Overview

The Zone Offroad 6.5-inch Lift Kit is designed for 2014–2018 Chevrolet Silverado and GMC Sierra 1500 4WD trucks. This system delivers the height, stance, and ground clearance needed to run 35-inch tires while maintaining solid ride quality and dependable handling. Because GM produced these trucks with three different factory upper control arm designs between 2014 and 2018, this kit is offered in configurations for either Cast Steel or Aluminum/Stamped Steel factory control arms — select the correct option based on your truck's existing setup. Multiple shock and strut package options are available to tailor the suspension to your preference and budget.

Important Notes

• Check Control Arms: GM produced cast steel, stamped steel, and aluminum control arms between 2014 and 2017. Use the reference image to identify your stock control arms. Cast steel arms will be replaced with cast steel; stamped steel and aluminum arms will be replaced with aluminum. Select the matching kit configuration before ordering.
• Crew Cab models: Add an Add-A-Leaf to your kit to offset the increased cab weight for a more level stance.
• Factory 17" and 18" wheels cannot be reinstalled due to tie rod end interference.
• All-wheel drive models may require a front CV driveshaft. See installation instructions for more information.
• Will NOT fit models equipped with MagneRide magnetic ride control.
• Use a 1/4" wheel spacer to accommodate factory 20" wheels; refer to the provided "Max Tire Size" chart for 20" wheel tire sizing.
• For optimal tire clearance and to reduce the need for trimming, use 20x9 wheels with 5.75" backspacing.
