QA1 MD618-14500 Pro Coil Shock System
Overview
If you're looking to customize the ride height of your 2015-2020 Ford F-150, the QA1 MD618-14500 Pro Coil Shock System is an excellent choice. This fully bolt-in solution replaces the original equipment (OE) system, making it suitable for both 2WD and 4WD models. With adjustable drop options, you can achieve the perfect stance for your truck.
Ride Height Adjustability
Getting the right stance for your truck can often be a challenge. The MD618-14500 simplifies this with fully threaded front coil-over shock bodies, allowing you to adjust the ride height without the hassle of shims or spacers. This means you can easily fine-tune how your truck sits, whether you want a dramatic drop of 3"-5" using drop spindles or a more moderate 1"-3" with stock spindles.
Double-Adjustable Coil-Overs
For those who crave superior handling and control, the double-adjustable Pro Coil shocks are the ultimate choice. Designed for both street and track use, these shocks offer independent rebound and compression tunability. This feature allows you to tailor your suspension for exceptional handling, ensuring your ride is responsive and enjoyable.
Heavy Duty Shock Design
QA1 engineers have designed the MD618-14500 with the modern truck's weight and payload capacity in mind. Featuring an upgraded shock with polyurethane bushings and a robust 1" chromoly T-bar, this system is built to endure the rigors of daily use. The new bushing design is specifically chosen for durability, replacing traditional spherical bearings for enhanced performance.
Easy, Bolt-In Installation
Installation is a breeze with the MD618-14500, thanks to its fully bolt-in design. This thoughtful approach ensures that you can get your new suspension system up and running without any unnecessary complications.
