About this part

Product Details

Built with a steel body and a sealed hyperscrew, this QA1 27 Series shock absorber is designed for vehicles that need to keep their stock shock mounting locations. It features a specific 12-4 valving curve, which is a key detail for how the shock controls suspension movement. This shock is dyno-tested and serialized, meaning each unit is checked to ensure it performs exactly as intended right out of the box.

The monotube design helps with consistent damping, and the shock is built to be rebuildable and revalveable, so you can adjust it down the road if your needs change. With a compressed height of 14.3 inches and an extended height of 22.63 inches, it's made to fit specific applications. The T-bar top and bushing bottom ensure a solid connection to your suspension components.

This shock absorber is made in the USA and is a solid option if you're looking for reliable performance that retains your factory mounting points.
