The Powerslide Combat HXG Rocker Trinity Frame Spacers are replacement spacers for the Powerslide Combat Trinity frames.
 
The price is for 16 (8 threaded and 8 non-threaded) spacers. They are designed to rotate within the Combat Frame to rocker wheels to one of 5 different positions, each wheel to its own desired position. They go onto the inside and outside of the frames. This makes more sense if having the Combat Frames as they are unique.  The frames of course come with these spacers, but as they can be lost...   Replacements are here when needed.
