QA1 27 Series Stock Mount Monotube Shock Absorber - Sealed Hyperscrew (IMCA) - 5-5 Valving - Steel

QA1 is well-known for making performance suspension components, and their 27 Series Stock Mount Monotube Shock Absorber is a solid choice if you need to keep your stock mounting locations intact. This shock is built with a large steel body and features a sealed hyperscrew design, often used in IMCA racing classes where specific rules apply. It's designed to bolt right in where your original shocks were, making installation straightforward for these classic Impalas.

This particular shock has a compressed height of 14.3 inches and extends to 22.63 inches, with a 5-5 valving curve that offers a good balance for many applications. Every QA1 shock is put through a dyno test and given a serial number, so you know it's ready to perform right out of the box. Plus, it's built to be rebuilt and revalved, meaning you can tune it further down the road if your needs change. It's made right here in the USA.
