Product Details

KYB Excel-G Part Number 3440013 is engineered for the rear position on 2014-2018 Mazda CX-5 models. It is designed to restore the suspension’s original damping characteristics rather than change ride height or handling balance. This makes it a practical choice for replacing worn rear shocks on a Mazda CX-5 when the goal is to recover predictable control, stable lane changes, and consistent braking response. This part cross-references Monroe Shocks & Struts 5530 and 5546 for the same application.
