KYB Excel-G Rear Left Strut for Mazda Protege

The KYB Excel-G 333277 is a rear left suspension strut for select Mazda Protege and Protege5 models. Built to restore original ride control and handling, it uses OE-style calibration to bring back stable braking, lane change response, and body control.

• Nitrogen gas-charged, twin-tube design for consistent damping
• Vehicle-specific, hand-assembled damping valves for tire contact and steering response
• Triple-lip fluid seal helps reduce oil and gas leakage
• Strong strut body and bracket design helps minimize flex and maintain alignment
• Made in the USA
• Electronic safety systems rely on suspension performance that matches factory intent

Product Details

KYB Excel-G is built on the same OE assembly lines used for KYB original equipment products and is calibrated to restore the vehicle’s designed performance rather than change it. For Mazda Protege rear suspension service, part number 333277 provides a direct replacement approach for drivers looking to recover factory-like ride control, stability, and handling balance. This part cross-references Monroe Shocks & Struts (e.g., 71589) for the same application.

Compatible With 1999-2003 Mazda Protege, rear left, and 2002-2003 Mazda Protege5, rear left. The KYB Excel-G 333277 is a practical choice when the goal is to return the suspension to original operating characteristics on these Mazda models.

Common Problems This Strut Can Address

• Excessive bouncing or poor rebound control
• Reduced stability during braking and lane changes
• Uneven tire contact caused by worn damping performance
• Noisy or loose-feeling rear suspension behavior
• Loss of factory ride control on Mazda Protege and Protege5 models

Installation Notes and Tips

Fits 1999-2003 Mazda Protege, rear left, and 2002-2003 Mazda Protege5, rear left. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part number SM5456, to reduce noise and vibration, and a KYB strut boot, part number SB102, to help protect the strut from dirt, debris, and salt.
