The Bilstein 25-316773 is a rear shock absorber from the B8 8100 series, sized for 4WD Ford F-150 trucks with a rear lift of 0 to 0.5 inches. It is a direct replacement for the factory rear damper, so an owner who has leveled or lightly lifted the back of a 4WD F-150 can restore controlled damping without moving to a full suspension system. Against a worn stock shock or a budget replacement, a purpose-matched Bilstein unit suits drivers who want the rear end to stay composed on washboard gravel, under towing loads, and over rough trail sections.
Confirm your application before ordering. This part is listed for 4WD F-150 models only, and the model-year coverage and equipment exclusions should be checked against your VIN with the manufacturer. Look up the manufacturer's installation instructions before starting, and verify hardware and torque specs there.
