QA1 27 Series Stock Mount Monotube Shock Absorber - Sealed Hyperscrew (IMCA) - 3-12 Valving - Steel

QA1 is known for making performance suspension components, and their 27 Series stock mount monotube shock absorber is a solid choice for your 1971-1996 Chevrolet Impala. This shock is designed to work with your car's original mounting locations, making installation straightforward. It features a durable steel body with a zinc plating to help resist corrosion, keeping it looking good and functioning well over time. The 46mm hard-anodized piston and the 3-12 valving offer precise control over your suspension's movement, especially at lower shaft speeds, which helps keep the car stable and gives you a better feel for what the road is doing.

This particular shock uses a sealed Hyperscrew design, which is often a requirement for certain racing classes like IMCA Southern Sport Mods. The linear valving is a key feature because it provides a consistent damping curve, leading to a more predictable car and making it easier for the driver to feel and react to the car's behavior. Plus, these shocks are built in the USA and are designed to be rebuilt and revalved by racers, offering excellent repeatability for consistent performance run after run. Every shock is also dyno-tested and serialized before it leaves the factory, so you know you're getting a part that meets QA1's high standards.
