These Jafab lifted H1's aren't my cup of tea. One of these went wheeling with the psychos in big bear and it broke halfshafts on the first rock.
It's all show and no go.
The only H1/HMMWV that can handle wheels that big is the oshkosh kit, it has huge tires, but it has a inline cat 6 engine, and a TAK4 suspension and axle kit from a 7-ton/Mrap.
