Detailed Description

The KYB Excel-G 3440216 is engineered for drivers who want the suspension to perform as originally intended. It focuses on restoring ride comfort, stability, stopping control, lane change responsiveness, and overall handling rather than altering the vehicle’s character. For Mazda CX-30 rear fitments, this shock absorber provides a factory-style replacement solution that matches OE design intent.

KYB’s Excel-G line is produced on the same assembly lines used for KYB original equipment products and uses the same quality standards found in its OEM supply program. The result is a suspension shock absorber that supports consistent damping performance and predictable road feel. This part number, 3440216, is also referenced by DGH928700A and DGJ428700A for the same application.

What It Helps Address

• Excessive bouncing after bumps
• Loose or unsettled handling feel
• Reduced lane change response
• Loss of ride control and stability
• Uneven damping performance from a worn shock absorber

Installation Notes and Tips

Verify the rear application, mount style, and dimensions before installation. Confirm compressed length, extended length, and stroke length against the removed part to ensure proper suspension travel. This shock absorber is listed for 2020-2025 Mazda CX-30 rear applications, and fitment should be matched to the vehicle’s exact configuration before service.
