Excel-G Product Line Details

KYB Excel-G is the brand’s OE-style replacement line for drivers who want factory-like suspension behavior rather than a changed ride feel. For the Mazda CX-30, this front left strut is tuned to match the vehicle’s original damping characteristics and maintain predictable response during braking, cornering, and everyday driving. Part number 3340301 is also referenced for the same application under Monroe Shocks & Struts cross-reference numbers 172286 and 182286.

What This Strut Helps Address

• Excessive bouncing or oscillation after bumps
• Reduced front-end control during braking
• Loose or delayed steering response in lane changes
• Uneven ride quality from a worn front left strut
• Handling instability on the Mazda CX-30

Installation Notes and Tips

Verify front left placement before installation and confirm the upper mount thread specification of 12x1.25. Compare compressed length, extended length, and stroke length against the removed part to confirm proper replacement. Professional suspension service is recommended, and alignment should be checked after strut replacement on the Mazda CX-30.
