QA1 27 Series Stock Mount Monotube Shock Absorber - Sealed Hyperscrew (IMCA) - 5-4 Valving - Steel

You're getting one QA1 27 Series Stock Mount Monotube Shock Absorber, specifically the 27A685-4M model. This shock is built with a steel body and features a sealed hyperscrew design, often used in IMCA racing classes. It's designed to work with stock mounting locations, making installation straightforward if you're keeping your original setup.

This shock absorber has a compressed height of 14.3 inches and an extended height of 22.63 inches, with a T-bar top and a bushing bottom. The 5-4 valving curve is tuned for a responsive feel, and each QA1 shock is dyno-tested and serialized to ensure it performs at its best right out of the box. Because it's racer rebuildable and revalveable, you can adapt it to changing needs or refresh it for continued use.

This is a solid option if you're looking to maintain stock shock mounting points on your 1971-1985 or 1994-1996 Chevrolet Impala, or other compatible GM vehicles from the late 70s and 80s. QA1 builds these shocks in the USA, focusing on performance and durability for demanding applications.
