QA1's complete lowering kit transforms your F-150 with aggressive stance and precision handling. The front features adjustable Pro Coil coilovers paired with drop spindles for maximum customization, while the rear flip kit with shackle/hanger maintains ride comfort. Independent compression and rebound adjustability on the double-adjustable shocks lets you dial in perfect performance—whether cruising streets or attacking the track. Drop your truck and elevate your control.
Full-range stance control: Front coilovers with spindles deliver a 3"–5" drop; rear system delivers 3.5"–5.5" with 1" increments for perfect rake.
Heavy-duty build for trucks: Upgraded shock bodies, poly bushings, and a 1" chromoly T-bar handle modern F-150 weight and payload.
Track-grade tuning: Double-adjustable shocks (independent C/R) sharpen response and let you dial comfort vs. control.
Bolt-in simplicity: No welding; engineered brackets and hardware for a clean, reversible install.
Ride quality up, not down: Geometry + valving work together for composed daily driving and confident cornering.
Best-in-class coverage: Lifetime shock warranty.
Made in USA: Designed and built in Lakeville, Minnesota.
Front: 3"–5" (with included drop spindles)
Rear: 3.5"–5.5", adjustable in 1" steps
4×4 note: Rear drop is effectively ~1" more vs. 2WD due to removal of the OE block.

Set initial ride height on the coilovers, then lock collars.

Plan for alignment and headlight aim after lowering.
Street vs. track? Start shocks around mid-clicks, then tune compression for roll control and rebound for ride/oscillation.
