KYB 343419 Shock Absorber - Rear

KYB Excel-G Rear Shock for Volvo

The KYB Excel-G 343419 is a rear suspension shock absorber engineered to restore original ride control, stability, stopping response, lane-change behavior, and handling. It is a direct OE-style replacement for select Volvo C30, S40, and V50 models, with vehicle-specific damping calibrated for factory performance.

Built on KYB’s OE assembly lines, the Excel-G line is designed to return the suspension to its original operating characteristics rather than alter ride feel. For Volvo owners searching for a rear shock absorber that matches factory control on the C30, S40, or V50, part number 343419 is a focused replacement option.

• Nitrogen gas-charged twin-tube construction
• Triple-lip fluid seal helps reduce oil and gas leakage
• Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
• Strong strut body and bracket design helps minimize flex and maintain alignment

Product Details

KYB Excel-G is an Original Equipment for the Aftermarket (OEA) line built to match the performance profile of the original suspension. This rear shock absorber uses OE-quality components and factory-style calibration to support consistent damping on the Volvo C30, Volvo S40, and Volvo V50. Part number 343419 is designed for drivers who want to restore suspension response without changing the vehicle’s intended ride characteristics.

This part cross-references Monroe Shocks & Struts 5617 for the same application.

What It Helps Address

• Excessive rear bounce after bumps
• Loose or unsettled handling in turns
• Reduced braking stability from worn rear damping
• Uneven tire contact caused by weak shock control
• Delayed body control during lane changes and road transitions
