2014-2018 GMC Sierra 1500 V6 4"/7" Lowering Kit - Cast Arms
This Trekline complete lowering package is organized around the Sierra 1500 chassis so the major drop components work together as one setup. The listed configuration targets a 4 inches front drop and 7 inches rear drop.
Vehicle Fitment:
- 2014-2018 GMC Sierra 1500
- Engine: V6 application for this SKU
- Drivetrain: Fits 2WD, 4WD and AWD applications when the remaining fitment requirements are met.
Kit Contents:
- 2-inch drop spindles (pair)
- 2-inch front lowering coils (pair)
- 7-inch rear axle flip kit
Important Fitment & Installation Notes:
- Spindle / control-arm fitment: The rest of the lowering kit is shared; the drop spindle is the component that changes with upper-control-arm design. Use Trekline 8000114 on cast-arm trucks and Trekline 8000124 on stamped-steel or aluminum-arm trucks. Confirm the upper control arm before ordering.
- MagneRide: Does not fit trucks equipped with MagneRide / Magnetic Ride Control.
- Wheel clearance: Drop-spindle applications require 17-inch or larger wheels.
- Trekline does not call for a C-notch with this listed drop combination; always verify real-world axle-to-frame clearance after installation.
- Rear drop shocks are not included with this SKU. Verify shock travel for the final ride height.
- Lowering amounts are referenced from factory-stock ride height; worn springs or previous suspension changes can change the measured result.
- Professional alignment and a full clearance/fastener inspection are recommended after installation.
