• Part number 343156 for direct catalog identification

Product Details

The KYB Excel-G line is calibrated to return the vehicle to its original damping characteristics rather than change ride feel. This shock absorber is made on KYB OE assembly lines using OE-quality components, which is why it is classified as an Original Equipment for the Aftermarket solution. For drivers searching for a front shock absorber for 1971-1973 Ford Mustang or a front suspension shock for 1968-1971 Mercury Montego, KYB 343156 provides a direct-fit service part focused on control and consistency. This part cross-references Monroe Shocks & Struts (e.g., 5823) for the same application.

What It Helps Address

• Excessive front-end bounce after bumps
• Loose or delayed steering response
• Reduced braking stability during weight transfer
• Uneven tire contact from weak damping control
• Body movement that affects lane changes and cornering
