KYB Suspension Shock Absorber P/N:343148
Smooth out a worn ride and restore factory-level control with the KYB Excel-G Gas Shock Absorber 3450017, a nitrogen gas-charged, twin-tube KYB shock absorber that drops in as the rear damper for the 2016-2024 Chevrolet Express 2500, 2016-2024 Chevrolet Express 3500, 2016-2024 GMC Savana 2500, and 2016-2024 GMC Savana 3500. See the Buyer's Guide tab for engine-level fitment.
The Excel-G is built on the same KYB OE assembly lines as its OEM units, earning the OEA (Original Equipment for the Aftermarket) classification — calibrated to restore the vehicle's original designed performance rather than change it.
KYB-recommended OEM replacement. Sold individually; replacing both rear shocks together as a matched pair is recommended for balanced, even control.
