KYB 19-23 Mazda 3 Excel-G Gas Strut - Front Left - 3340341

The KYB Excel-G Gas Strut (Part # 3340341) is a direct-fit front left strut designed specifically for the 2019–2023 Mazda 3. Engineered as an OE-style replacement, this KYB Excel-G strut restores the controlled, comfortable ride your Mazda 3 had from the factory — making it a go-to choice for drivers dealing with worn or leaking front suspension components. Whether you're on the Base, Preferred, Premium, Select, or Turbo trim, this strut is built to drop right in without modifications.

Key Features & Benefits

• KYB Excel-G Gas Technology: The Excel-G line uses a pressurized gas design that helps minimize the "fade" effect common in worn hydraulic struts, delivering more consistent damping performance mile after mile.
• OE-Style Direct Replacement: Engineered to match original equipment specifications for the 2019–2023 Mazda 3, meaning no drilling, no custom brackets, and no guesswork — just a clean swap back to factory-quality ride and handling.
• Front Left Position: This specific unit (MPN 3340341) is calibrated and configured for the front left position. Make sure to source the correct side when replacing struts to maintain balanced suspension performance.
• Restores Ride Comfort & Handling: Worn struts cause excessive body roll, nose dive under braking, and a bouncy, unsettled ride. Replacing with a quality KYB Excel-G unit restores the Mazda 3's intended ride quality and steering response.
• Broad Trim Compatibility: Fits an impressive range of 2019–2024 Mazda 3 trims and engine variants, making it one of the most versatile front strut options for fourth-generation Mazda 3 owners.

Frequently Asked Questions

Q: Does this strut fit both the sedan and hatchback versions of the 2019–2023 Mazda 3?
A: The fitment data lists compatibility by year, trim, and engine submodel rather than body style. We strongly recommend contacting the ThreePiece.us fitment team at 813-535-5801 to confirm compatibility for your specific body style before ordering.

Q: Is this the complete strut assembly, or just the strut cartridge/insert?
A: This is listed as a strut unit (not a full loaded strut assembly with spring and mount pre-installed). Depending on your installation setup, you may need to transfer your existing spring, upper mount, and bump stop onto the new strut. Consult a qualified technician if you are unsure about what additional components are needed.

Q: Do I need to replace both front struts at the same time?
A: While this listing covers the front left position only, it is generally recommended by suspension technicians to replace struts in axle pairs (both front or both rear) to maintain balanced handling and even ride quality. You would need to order the corresponding front right KYB Excel-G strut separately.

Q: Can I use Affirm to finance this purchase?
A: Yes — Affirm financing is available at checkout on ThreePiece.us, allowing you to split the cost of your suspension parts into manageable payments. Free shipping is included on every order regardless of financing method.
