Product Details
QA1 is known for making performance suspension components, and their 27 Series shock absorber is a great example of that. If you're working on a 1971-1996 Chevrolet Impala and need a shock that uses the factory mounting points, this is a solid option. It's a monotube shock, which generally offers better damping control than twin-tube designs because it keeps the oil and gas separated, preventing aeration and fade.
This particular shock features a sealed hyperscrew design, making it legal for IMCA Southern Sport Mod classes. The valving is a 3-5M, which is designed to give you good control over suspension movement at low speeds without making the ride too harsh at higher speeds. This linear valving helps keep the car stable and allows the driver to better feel what the chassis is doing. The body is zinc-plated for corrosion resistance, and the whole unit is built in the USA. Plus, it's designed to be rebuilt and revalved by racers, meaning you can tune it to your specific needs and maintain its performance over time.
Every QA1 shock is dyno-tested and serialized before it leaves the factory, so you know you're getting a part that's ready to perform. This shock absorber is a direct fit for the stock mounting locations on your Impala, simplifying installation.
