QA1 27 Series Stock Mount Monotube Shock Absorber - Sealed Hyperscrew (IMCA) - 8-3 Valving - Steel

If you're working on a 1971-1996 Chevrolet Impala and need a shock that keeps the stock mounting locations, this QA1 27 Series monotube shock absorber is a solid choice. It's built to work with the original setup, making installation straightforward without needing to modify your chassis. This shock absorber features a steel body and a sealed hyperscrew design, often used in IMCA racing classes where specific mounting requirements are common.

QA1 puts each of these shocks through a dyno test and assigns a serial number, so you know you're getting a unit that performs consistently right out of the box. The 8-3 valving is a popular choice for a good balance of control and comfort, and the fact that it's rebuildable and revalveable means you can adapt it if your needs change down the road. It's made in the USA, which is always a good sign for build quality.
