KYB 349045 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

KYB Excel-G part number 349045 is a rear suspension shock absorber built to restore original ride control, stability, stopping response, lane-change behavior, and handling. It is a nitrogen gas-charged, twin-tube design made on KYB OE assembly lines with OE-quality components for a direct replacement approach.

The Excel-G line is KYB’s OEA-style replacement range, focused on returning the vehicle to its designed damping characteristics rather than changing the ride feel. For Mercedes-Benz Sprinter 2500 and Dodge Sprinter applications, 349045 is a practical choice when rear suspension performance has declined.

• KYB recommended OEM replacement shock
• Vehicle-specific, hand-assembled damping valves for controlled tire contact and steering response
• Triple-lip fluid seal to reduce oil and gas leakage
• Strong strut body and bracket construction to minimize flex and help maintain alignment
• Dust cover included
• R-stop and nitrogen gas-charged twin-tube construction

Excel-G Product Line Details

KYB Excel-G shocks and struts are calibrated to restore the vehicle’s original suspension behavior. The line uses OE-style construction and components, and KYB supplies shocks and struts to new vehicle manufacturers, which supports the OE-focused design of this replacement part. Part number 349045 is engineered for rear suspension service where consistent damping and body control matter.
