QA1 LK12-GMT05 4/5 Lowering Kit with Drop Spindles Double Adjustable Shocks

The QA1 LK12-GMT05 is a complete 4-inch front / 5-inch rear lowering kit engineered specifically for 2019–2026 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks in both 2WD and 4WD configurations. Built around QA1's double adjustable Pro-Coil front coilover suspension and a matched double adjustable rear drop kit, this system gives you independent control over compression and rebound damping for a dialed-in ride at any lowered height.

Key Features:

• 2–4 inch front drop range and 3–5 inch rear drop range for an aggressive, street-focused stance
• Double adjustable Pro-Coil front coilovers with independent compression and rebound tuning
• Matched double adjustable rear drop kit for balanced front-to-rear performance
• Drop spindles included to maintain proper suspension geometry at lowered ride height
• Compatible with both 2WD and 4WD Silverado 1500 and Sierra 1500 applications
• Fully bolt-in installation — no cutting or welding required
• Fully threaded coilover shock bodies for precise ride height adjustment without shims or spacers
• Engineered as a matched system to maintain balance and predictable handling

QA1 engineered the LK12-GMT05 specifically for the weight, suspension geometry, and real-world demands of late-model half-ton trucks. The Pro-Coil front suspension and double adjustable rear drop kit work together as a complete, matched system — eliminating the compromises of pieced-together lowering solutions. The result is a truck that sits lower, handles better, and rides the way you want it to.
