KYB Suspension Shock Absorber P/N:349147

Settle the ride and help restore factory-level control with the KYB Excel-G Rear Shock Absorber 349147, a nitrogen gas-charged, twin-tube damper. It's a rear-position, direct-fit replacement for the 2011-2024 Chevrolet Silverado 2500 HD, 2011-2024 Chevrolet Silverado 3500 HD, 2011-2024 GMC Sierra 2500 HD, and 2011-2024 GMC Sierra 3500 HD — see the Buyer's Guide tab for the full engine-level list.

• OEA design: KYB's Excel-G is built on the same OE assembly lines with OE-quality components and calibrated to restore the vehicle's originally designed performance, not change it — earning KYB's Original Equipment for the Aftermarket classification.
• Twin-tube, gas-charged: a nitrogen gas-charged, twin-tube design intended to help restore the designed control and handling of your heavy-duty GM truck.
• Triple lip fluid seal: reduces the chance of oil and gas leaking out.
• Vehicle-specific valving: hand-assembled in-house damping valves manage tire contact, steering response, and body movement, and help keep electronic safety systems performing as designed.

For balanced ride control, best practice is to replace shocks in axle pairs; worn units may show excessive bounce, nose-dive, or reduced stability.
