KYB 344615 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

The KYB Excel-G 344615 is a rear suspension shock absorber built to restore original ride control, stability, and handling. It is a direct OE-style replacement for select Ford truck applications, including the Ford F-150 and Ford F-250, with calibration focused on factory-designed performance rather than changing the vehicle’s character.

Key Features

• KYB recommended OEM replacement shock for rear suspension service
• Nitrogen gas-charged, twin-tube design for consistent damping response
• Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
• Triple-lip fluid seal helps reduce the chance of oil and gas leakage
• Dust cover included
• Made in USA
• Strong strut body and bracket design helps minimize flex and maintain alignment under load

Excel-G Product Line Details

KYB Excel-G shocks and struts are built on KYB OE assembly lines using OE-quality components and Original Equipment for the Aftermarket (OEA) calibration. The goal is to return the suspension to the vehicle’s original control characteristics, which is important for braking stability, lane-change response, and predictable handling on work trucks and daily drivers alike. This KYB 344615 rear shock absorber is part of that OE-focused line.
