63 Series Shock 7in Front 5C/400R

The QA1 63 Series Shock 7in Front 5C/400R is a high-performance suspension component designed for street machines, hot rods, and restomod builds where ride quality and handling precision are paramount. This shock absorber serves as a direct bolt-in replacement for classic vehicle suspension systems, effectively managing chassis movement while ensuring comfort and predictability.

Featuring a 7-inch collapsed length and a 5-Coil, 400 lb/in Rate spring configuration, this shock provides the necessary stiffness to control weight transfer during acceleration and braking. The nitrogen-charged monotube construction prevents fade under sustained driving and minimizes aeration, making it ideal for both track performance and spirited road driving. Its 3.25-inch diameter allows for fitment in tight spaces, while its weight of 4.05 lbs helps reduce unsprung mass, enhancing steering response and ride compliance.

This shock is best suited for dedicated suspension builders and experienced mechanics working on frame-off restorations or modern chassis upgrades for vintage vehicles. Its design and performance characteristics make it a valuable addition for those looking to elevate their vehicle's handling and ride quality.
