KYB Suspension Shock Absorber P/N:3440137
Smooth out a bouncy, worn-out ride with the KYB shock absorber 3440098, a nitrogen gas-charged, twin-tube Excel-G rear damper. This KYB gas shock absorber is a direct-fit rear replacement for the 2017-2024 Ford F-250 Super Duty and 2017-2022 Ford F-350 Super Duty — see the Buyer's Guide tab for engine-level fitment.
Part of KYB's Excel-G line (classified OEA, Original Equipment for the Aftermarket), it is built on the same KYB OE assembly lines with the same OE-quality components and calibrated to restore the vehicle's original designed performance rather than change it.
KYB recommends replacing shocks as a matched set for even, balanced ride control; this listing is for one rear shock. When comparing KYB shock absorber price, this is the professional technician's preferred OE-replacement choice.
