63 Series Shock 7in

The 63 Series Shock 7in by QA1 is a high-performance monotube shock absorber engineered for builders and enthusiasts seeking precision suspension tuning on custom and modified vehicles. This 7-inch stroke unit is purpose-built for independent front suspension setups, lowered platforms, and custom chassis applications where ride quality, load control, and adjustability demand professional-grade components. Whether you're fabricating a hot rod, restomod, or competition vehicle, the 63 Series delivers the damping response and durability required for demanding driving conditions.

QA1's monotube design uses a pressurized nitrogen charge to separate the piston rod from the fluid column, eliminating cavitation and providing consistent damping across the full stroke range—critical when cornering hard or absorbing impacts under load. The 7-inch travel accommodates moderate to aggressive suspension geometry changes while maintaining progressive spring rates and predictable body control. Weighing just 4.2 lbs and measuring a compact 3 x 3 x 25 inches, this shock integrates cleanly into tight engine bays and custom suspension mounts without sacrificing mounting rigidity or performance envelope.

The 63 Series Shock 7in excels in independent front suspension applications, making it ideal for A-arm suspensions, tubular control arms, and adjustable ride-height platforms on street rods, custom trucks, and vintage restorations. Installation requires proper suspension geometry alignment and compatible mounting brackets—work with a suspension specialist or fabricator to ensure correct valving orientation and spring preload setup. This shock pairs effectively with complementary QA1 coilover systems and is compatible with vehicles using 1.5-inch bore diameter housings.
