KYB Suspension Shock Absorber P/N:345609

Keep every commercial mile under control with the KYB Suspension Shock Absorber 345609, a nitrogen gas-charged, twin-tube Excel-G damper built to restore your truck's original ride control, stability, and handling. It's a direct-fit replacement across a wide range of medium-duty and cab-over trucks, including the 2016-2023 Chevrolet LCF 3500, 1987-2010 Chevrolet W4500 Tiltmaster, 1986-2010 Isuzu NPR, 1999-2022 Isuzu NPR-HD, and 1994-2009 UD 1400 — see the Buyer's Guide tab for the full list. This shock is cataloged in both FRONT and REAR positions depending on the application.

• OEA calibration: Made on KYB's OE assembly lines and calibrated to restore the vehicle's original designed performance, earning the Original Equipment for the Aftermarket classification.
• Triple-lip fluid seal: Reduces the chance of oil and gas leaking out.
• Vehicle-specific damping valves: Hand assembled in-house to manage tire contact, steering response, and body movement.
• Strong strut bodies and brackets: Among the thickest in the industry to minimize flex and help maintain correct alignment.

KYB recommends the Excel-G as an OEM replacement shock for heavy-duty trucks and commercial vehicles. Made in USA. Sold individually; replacing shocks in axle pairs is recommended for balanced ride control.
