Kit #: LK11-GMT03
If you want a lowered look and unmatched ride comfort, look no further. This comprehensive QA1 lowering kit is an all-in-one solution specifically designed to enhance your 2007–2016 Chevy Silverado 1500 / GMC Sierra 1500. Including QA1’s front Pro Coil Coil-Overs, a Rear Drop Kit, and optional drop spindles, this setup delivers maximum adjustability for your ride height while significantly improving handling and overall performance.
Lowered Look, Unmatched Ride Comfort
1. Ride Height Adjustability
- Front Adjustment: Achieve a 1–3" drop with the fully threaded coil-over shock bodies, eliminating the hassle of shims or spacers. Pair these coil-overs with drop spindles (included in this kit) to reach a 3–5" drop for a truly custom stance.
- Rear Adjustment: Choose between a 2–3" drop or a 4–6" drop to dial in the perfect rake. A 2" adjustment range in the rear allows you to fine-tune your truck’s stance.
2. Heavy-Duty Shock Design
- Engineered for Modern Trucks: QA1’s Pro Coil system is upgraded with polyurethane bushings and a 1" chromoly T-bar to support the higher payload and curb weight of today’s pickups.
- No Spherical Bearings: Designed for daily-driven trucks, these heavy-duty components extend durability and stability on the road.
3. Single-Adjustable Shocks
- Versatile Performance: QA1’s Proma Star single adjustable shocks let you effortlessly switch between a comfortable cruise setting and a more spirited, performance-oriented feel—ideal for daily commutes or winding back roads.
4. Rear Shackles and Hanger Kits
- Built to Last: Manufactured from heavy-gauge steel with a powder-coated finish, QA1’s shackle and hanger kits offer long-term durability, maintaining ride quality even with a significant drop.
- Comprehensive Lowering: They provide the rear drop range your truck needs without compromising comfort or overall performance.
Easy, Bolt-In Installation
- Hassle-Free Fitment: Every kit is fully bolt-in, reusing factory mounting locations. You won’t need specialized tools or extra fabrication to get your Silverado or Sierra sitting just right.
Made in the USA
- Quality You Can Trust: QA1 develops and manufactures these suspension components in Lakeville, Minnesota, ensuring rigorous quality standards and reliable American craftsmanship.
Fitment Notes
- Axle U-bolts Not Included: Please source these separately if needed.
- Not for 1500HD Trucks: This kit is designed exclusively for 2WD half-ton models.
- Offset Upper Control Arm Bushings: May be required (AcDelco PN 45K0201) for vehicles lowered more than 2.5” to maintain factory alignment specifications.
