QA1 27 Series Stock Mount Monotube Shock Absorber - Hyperscrew - 4-4 Valving - Steel

This QA1 27 Series shock absorber uses a steel monotube body and features a 4-4 valving setup, meaning it's tuned for a specific balance of compression and rebound control. It's built to work with your Impala's original mounting locations, making it a straightforward swap if you're looking to replace worn-out shocks without modifying your suspension setup. The compressed length is 10.38 inches, and it extends to 15.67 inches, fitting the geometry of your vehicle.

Each QA1 shock is dyno-tested and serialized, so you know you're getting a unit that performs exactly as specified. This particular shock is also designed to be rebuilt and revalved, which is a nice touch if you ever want to fine-tune the suspension for different driving conditions or track use down the road. It's a well-built option made in the USA, designed to give you dependable performance for your classic Impala.
