About this kit
N3 Rear Shocks, fitment-checked
Rough Country 23143_I is a pair of N3 rear shocks for 1970–1976 Ford F-100 4WD and 1976–1979 Ford F-150 4WD applications. They fit trucks running between 0 and 3 inches of suspension lift only. Nitrogen charging, 10-stage variable valving, and a 35mm piston handle the damping work. Covered by a 3 Year Limited Warranty.
These N3 rear shocks cover 1970–1976 Ford F-100 4WD and 1976–1979 Ford F-150 4WD trucks across Base, Custom, Northland, Ranger, and XLT submodels shown in the fitment section. They are valved for stock height through 3 inches of suspension lift, so confirm your current setup before ordering. Each shock uses an 18mm chromed piston rod inside a 54mm body, with military-spec fluid rated down to -40 degrees Celsius and rubber bushings at the mounts. The box holds one N3 shock pair, and Rough Country lists the job at 1-2 hours.
