Product Details
This QA1 27 Series monotube shock absorber uses a sealed hyperscrew design, a key detail for consistent damping, especially in racing applications like IMCA. It’s built to fit directly into your vehicle’s original shock mounting locations, making installation straightforward without needing to modify your chassis. This shock is dyno-tested and serialized, so you know it’s ready to perform right out of the box.
The steel body construction houses a precise 8-2 valving curve, offering a solid balance for a variety of driving conditions. With a compressed height of 14.3 inches and an extended height of 22.63 inches, it’s designed to work within your suspension’s travel limits. Plus, the fact that it’s rebuildable and revalveable means you can adapt it to changing needs or refresh its performance down the road, extending its usefulness.
