It's a fully bolt-in solution that replaces the OE system, allowing both 2WD and 4WD owners to customize their ride height to their liking. With a drop of 3"-5" using drop spindles or 1"-3" with stock spindles, this kit provides the perfect stance for your truck. Ride Height Adjustability We understand that achieving the perfect stance for your truck can be a challenge. That's why we've created a solution that makes it easy to adjust your ride height. Pro Coil kits feature fully threaded, aluminum body Pro Coil shocks which allow you to effortlessly dial in how your truck sits. Single-Adjustable Coil-Overs QA1's single-adjustable Pro Coil coil-over shocks are tailored for street-driven trucks that also hit the track and are fully adjustable to give you complete control over your ride. Adjusting your shocks is a breeze with a turn of the adjustment knob, making it effortless to switch between a comfortable ride and a more aggressive valving when the need arises.Heavy Duty Shock Design QA1 Engineers have tackled the challenge of supporting the weight and payload capacity of modern trucks by designing a heavy-duty version of our Pro Coil system, which features an upgraded shock with polyurethane bushings and a 1" chromoly T-bar. The system's new bushing design was specifically chosen to withstand the daily use of trucks, rather than using spherical bearings. Easy, Bolt-In InstallationOur commitment to thoughtful product design is evident in every fully bolt-in kit we produce, which guarantees a hassle-free installation process.
