KYB 3440219 Suspension Shock Absorber - Rear

Overview

KYB Excel-G shock absorber 3440219 is built to restore original ride control, stability, and handling performance. It is an OE-style replacement for rear suspension service on select Hyundai Tucson and Kia Sportage applications, with calibration focused on factory-like response rather than changing the vehicle’s character.

Key Features

• Nitrogen gas-charged, twin-tube design for consistent damping performance.
• Made on KYB OE assembly lines with OE-quality components.
• Internal rebound spring helps support controlled suspension movement.
• Restores original designed performance for ride control and lane-change response.
• Fits rear suspension applications on select Hyundai Tucson and Kia Sportage models.

Detailed Description

The KYB Excel-G 3440219 is engineered as an Original Equipment for the Aftermarket replacement shock absorber. KYB builds the Excel-G on the same production lines used for OE supply, using components matched to factory specifications so the part restores the vehicle’s intended suspension behavior. This makes it a practical choice for drivers and technicians servicing a Hyundai Tucson or Kia Sportage rear suspension where predictable ride control and handling response matter. Part number 3440219 is also cross-referenced to 55307CH210 and 55307DW300 for the same application.

Excel-G is part of KYB’s OE-focused product line, aimed at maintaining the vehicle’s original balance of comfort, stability, stopping, and steering response. The twin-tube, gas-charged construction and OE-calibrated valving support consistent damping under normal driving conditions.

Common Issues It Can Address

• Excessive bouncing after bumps.
• Reduced stability during lane changes.
• Loose or unsettled rear suspension feel.
• Uneven damping response from worn shock absorbers.
• Loss of factory-like ride control.
