About this kit
M1 Monotube Rear Shocks, fitment-checked
Rough Country 770789_F is a rear shock pair from the M1 monotube line, fitted to 1999-2004 Ford F-250 and F-250 Super Duty RWD trucks. Each shock uses a 46mm digressive piston inside a 2-inch seamless extruded body, with an 18mm case-hardened chromed rod and vulcanized natural rubber bushings. This part number is sold in pairs.
These M1 monotube rear shocks cover 1999-2004 Ford F-250 RWD trucks in XL, XLT, and Lariat trim, plus F-250 Super Duty RWD models including King Ranch. The 46mm monotube layout with digressive valving reacts as the surface under the truck changes, and the deflective-disc design handles rebound and compression independently without manual adjustment. Bodies are zinc plated against road salt and weather. Rough Country lists an installation time of 1-2 hours, so this is a realistic weekend-morning job with the truck on stands. Order quantity one to receive the pair.
