About this kit
N3 Rear Shock Pair, fitment-checked
Rough Country 23143_K is a pair of N3 rear shocks for the 1970–1979 Ford F-100 RWD. They fit only trucks already running 5.5-7.5 in of suspension lift, so confirm your current lift height first. Both shocks come in one box, and the kit carries a 3 Year Limited Warranty.
This N3 rear shock pair suits the 1970–1979 Ford F-100 RWD in Base, Custom, Northland, Ranger, Ranger Lariat, Ranger XLT, and XLT trim, provided the truck already sits on 5.5-7.5 in of suspension lift. The N3 design uses 10-stage variable valving, a 35mm piston inside a 54mm body, and an 18mm chromed rod, with nitrogen charge and military-spec fluid rated to -40 degrees Celsius. Rubber bushings handle vibration. Rough Country lists installation at 1-2 hours for the pair, which makes this a straightforward driveway swap with basic hand tools.
