KYB Suspension Shock Absorber P/N:3440100
KYB 565091 rear shock absorber for the 2008-2016 Ford F-250 Super Duty and other vehicles damps rear suspension movement as a high-pressure monotube gas shock. The large-bore KYB MonoMax is made only for trucks that tow, haul heavy loads or go off-road, with up to 40% more damping performance than standard shock absorbers.
Oil on the shock body, or a rear end that keeps moving after a bump, can mean a shock is worn. Before you replace a rear shock, rule out the springs, bushings and tires, which can also make a truck bounce or sway. Plan on changing both rear shocks at once, since they work as a pair; this listing is one shock.
This rear shock absorber fits the 2008-2016 and 1999-2004 Ford F-250 Super Duty and the 1999-2007 Ford F-350 Super Duty.
