KYB Suspension Shock Absorber P/N:3440137
KYB 565123 rear shock absorber for the 2005-2016 Ford F-350 Super Duty and other vehicles controls rear suspension movement on heavy-duty trucks. This KYB gas shock absorber is a large-bore monotube made for trucks that tow, haul heavy loads or go off-road.
Fluid on the shock absorber body, bouncing that carries on after a bump or a rear end that wallows under load can mean it is worn. These signs alone do not prove this part is the problem, since worn rear tires can feel similar. This listing is one shock absorber, and both rear sides are normally replaced together.
It fits the 2005-2016 Ford F-350 Super Duty and the 2005-2007 Ford F-250 Super Duty, with two shock absorbers per truck.
