This is an optional PSM 2.5mm B-MAX4 III Carbon M1 Chassis Shorty Conversion. This carbon main chassis was designed to fit Team Yokomo’s BMAX4 III when using a shorty style LiPo battery. It features PSM's unique AirMount battery mount system that will keep the battery secure, but will not affect chassis flex. This system allows the chassis to bend both directions left and right the same way so it can generate ideal traction and the flex adjustment can be easily set by adding or removing the included chassis stiffeners.

PSM 2.5mm B-MAX4 III Carbon Shorty Conversion Chassis
This conversion kit require additional parts if you use modified motor or when you have sensored combo with ESC without direction change option, in this case you must purchase differential house which allows differential unit position change to opposite. Also additional few, shorter screws are required - two screws from my set was to long to screw it to the end, additional tape for secure battery will be nice to have because after mounting stiffeners you will get naked screw which can damage your battery case.

Also instruction is useless, nothing about assembling all parts together or solving problems. I expect more for conversion kit at this price point.

If you want complete, high quality conversion kit from saddle pack to shorty you definitely should purchase original Yokomo lighweight kit for B-Max4 III, for this same price you will get all required parts.
