This is a pair of half shafts (swing shafts or dog bones) which will work    
with most Traxxas electric vehicles, the Nitro Street and the Nitro Buggy.    
But these will not work with the Nitro Hawk (they are too short).

Includes:                                                                      
        (2) inside shafts                                                    
        (2) outside shafts                                                    
        (4) universal joints (metal balls with 4 pins sticking out in a cross
            pattern)
