Product Description

The Bilstein 24-131742 is a B6 Performance front shock absorber engineered for the 2006-2015 Mazda MX-5 Miata (NC generation). Using Bilstein's 46mm monotube gas-pressure technology with NC-specific valving, this shock delivers noticeably sharper cornering response, reduced body roll, and superior road feedback compared to stock or worn OEM dampers - all while working seamlessly with the factory springs at stock ride height.

This shock is a favorite among NC Miata owners who want a meaningful handling upgrade without changing ride height, and is trusted by Spec Miata racers for its consistent, fade-free performance under sustained track conditions. It is sold as a single unit - two are required for a complete front shock replacement. Drivers installing aftermarket lowering springs should instead consider the Bilstein B8 Sport (24-131773) for proper spring preload and travel geometry at a lowered stance. The rear B6 companion shock is 24-131759.
