Restore controlled rear ride quality with the Focus Auto Parts Suspension Shock Absorber and Coil Spring Assembly (SC00039), a rear-position unit that pairs the damping shock and the load-carrying coil spring into a single serviceable assembly. It installs as a direct-fit replacement for the 1980-1989 Ford F-150 and 1980-1991 Ford F-250.
The shock absorber dampens suspension oscillation to keep the tires in contact with the road, while the coil spring supports the vehicle's weight and sets ride height. Signs this assembly may need replacing include excessive bouncing after bumps, a sagging or uneven rear stance, bottoming out over dips, or clunking from a worn spring or shock. If a worn rear shock or coil spring is the cause of these symptoms, this assembly replaces those components. Diagnose the cause before ordering to confirm the failure is in the rear suspension.
Interchange: Manufacturer part number SC00039.
