QA1 Pro Coil Front Coil-Over System - Double Adjustable for 2007-2018 Chevrolet Silverado 1500 / GMC Sierra 1500 4WD

The QA1 GD518-10950 Pro Coil Front Coil-Over System is the ultimate bolt-in suspension upgrade for your 2007-2018 Chevrolet Silverado 1500 or GMC Sierra 1500 4WD. This complete double-adjustable coil-over kit allows 1"-3" of lowering with stock spindles or up to 3"-5" with aftermarket drop spindles, giving you the perfect stance while dramatically improving ride quality, handling, and performance. The fully threaded aluminum body shocks offer independent rebound and compression adjustment (18 positions each) so you can fine-tune for daily driving, towing, or spirited cornering.

  • Adjustable Ride Height: 1"-3" drop with stock spindles or 3"-5" with drop spindles
  • Heavy-Duty Design: Upgraded shocks with polyurethane bushings and 1" chromoly T-bar for truck payload capacity
  • Bolt-In Installation: Direct replacement for the factory system no cutting or welding
