Detailed Product Description

The KYB AGX 743021 shock absorber is designed specifically for Ford Mustang vehicles, providing a reliable suspension upgrade or replacement. With a compressed length of 13.78 inches and an extended length of 19.69 inches, it offers a stroke length of 5.91 inches, ensuring smooth and controlled suspension travel. The lower mount uses an E2 type (12.8x38), while the upper mount is an S1 type (12mm), matching the factory mounting points for straightforward installation. This shock absorber includes a dust cover to protect internal components from debris and environmental damage. Additionally, the built-in B-stop and R-stop features help prevent over-compression and over-extension, maintaining suspension integrity and vehicle stability. The absence of an internal rebound spring indicates a design focused on consistent damping performance without additional spring tension inside the shock body.
