Product Details

KYB Excel-G is part of KYB’s OE replacement line, built on the same assembly lines and with the same quality component standards used for original equipment supply. The 341253 strut is engineered to restore the Mazda Miata’s original ride characteristics rather than change them, making it a practical choice for drivers who want factory-like control, predictable lane-change response, and stable braking behavior. This part cross-references Monroe Shocks & Struts (e.g., 71342) for the same application.

What This Strut Helps Address

• Excessive bounce or float after bumps
• Reduced steering precision during lane changes
• Nose dive under braking
• Uneven tire contact caused by worn damping
• Noise or vibration from aged suspension components

Installation Notes and Tips

Fits 1999-2005 Mazda Miata, front, recommended OEM replacement; excludes Sport Package models. KYB recommends replacing the front strut mounts with SM5139 to reduce noise and vibration, and adding a KYB strut boot, SB108, to help protect the strut from dirt, debris, and road salt. For best results, inspect related suspension components and perform a wheel alignment after installation.
