Learn more about the gross weight increase

The gross weight increase for 1963 through 1967 (172D-H models) require a one-time installation of three stringers in the tailcone. The stringers were added during production of the Cessna 172s during 1968 timeframe. Prior to purchasing the gross weight increase with the 180HP upgrade confirmation of the stringers installed is required. 6 Ply tires are also required if not already in place.
