May 31, 2023 – Lakeville, MN – QA1, a leading manufacturer of high-performance suspension and shock components, announces the launch of its Pro Coil coil-over system for 07-18 Silverado and Sierra trucks. This fully adjustable and bolt-in solution allows truck owners to customize their ride height and achieve the perfect stance.
“Our Pro Coil coil-over system is a game-changer for truck enthusiasts who want to take their ride to the next level,” said Jesse Cowles, Product Manager at QA1. “With the ability to adjust the ride height, our customers can easily achieve the perfect look they desire, while also improving their truck’s handling and ride quality.”
The Pro Coil coil-over system is a fully bolt-in solution that replaces the OE suspension and allows for a 4-6″ drop with the use of drop spindles. The system is available in two options: single-adjustable and double-adjustable coil-overs. The single-adjustable coil-overs allow for easy fine-tuning of the ride, while the double-adjustable coil-overs provide independent tunability for both rebound and compression, making them the perfect choice for performance enthusiasts.
In addition to ride height adjustability, the Pro Coil coil-over system features heavy-duty construction to withstand the weight and payload capacity of modern trucks. The system includes an upgraded shock and a 1″ chromoly T-bar.
Installing the Pro Coil coil-over system is a breeze, with new hardware and detailed installation instructions included. Plus, with registration, the shocks are backed by a best-in-class Limited Lifetime Warranty.
Don’t settle for a lackluster stance or subpar ride quality in your truck. Upgrade to QA1’s Pro Coil coil-over system and experience the ultimate in customization and performance.
