Product Details

KYB Excel-G is KYB’s OE replacement line for drivers who want the suspension to perform as the vehicle manufacturer designed. The 3340210 strut is made on KYB OE assembly lines using OE-quality components and is calibrated for original ride control rather than a changed ride feel. For Mazda CX-3 front suspension service, this part number 3340210 supports stable braking, lane-change response, and consistent handling.

This part cross-references Mazda DB4G34900A and DD5D34900A for the same application.

What It Helps Address

• Excessive front-end bounce or float
• Reduced steering precision during lane changes
• Uneven tire contact caused by worn damping
• Noise or vibration from a fatigued strut assembly
• Loss of factory-like ride control on a Mazda CX-3

Installation Notes

Install on the front left position only for the listed Mazda CX-3 applications. KYB recommends replacing the suspension strut and coil spring assembly according to the manufacturer’s instructions. To reduce noise and vibration, KYB also recommends new strut mounts, part number SM5884. Verify compressed length 13.7, extended length 21.06, and stroke length 7.36 during service.

Quality Assurance

KYB is a major OE supplier to vehicle manufacturers, and Excel-G is built on the same production lines used for OE applications. The 3340210 is an OEA-classified replacement designed to restore original performance characteristics for the Mazda CX-3.
