KYB 19-23 Mazda 3 Excel-G Gas Strut - Front Right - 3340340

The KYB Excel-G Gas Strut – Front Right (Part #3340340) is a direct-fit front strut designed specifically for the 2019–2024 Mazda 3 across a wide range of trims and engine configurations. KYB's Excel-G line is engineered to restore the original equipment ride and handling characteristics your Mazda 3 was designed to deliver — making this an ideal choice for drivers looking to replace a worn or leaking OE strut with a quality, vehicle-specific unit. Built to order in Japan, this strut is a precision-manufactured component intended to bring your Mazda 3's suspension back to factory spec.

Key Features & Benefits

• Vehicle-Specific Fit: Engineered exclusively for the 4th-generation Mazda 3 (2019–2024), this strut is designed to match OE mounting points, travel, and valving — no modifications required for a clean install.
• Gas-Pressurized Design: The Excel-G uses a monotube-style gas pressure design that helps resist fade and aeration, maintaining more consistent damping response compared to unpressurized units.
• OE Ride Restoration: KYB's Excel-G series is tuned to restore — not alter — your vehicle's original suspension geometry and comfort profile, making it well-suited for daily drivers and commuters who want their Mazda 3 to ride and handle like new.
• Made in Japan: This strut is manufactured to order in Japan, reflecting KYB's longstanding reputation for precision and quality control in suspension components.
• Front Right Position: This is a single strut for the front right (passenger side) position. Pair with the corresponding front left unit for a full front-axle refresh.
• Weight: ~9.5 lbs: A manageable component weight that assists with straightforward installation on a standard lift or jack stand setup.
