We see a lot of cars in the service bay with no battery tie-down. This is VERY hazardous to the health of your car as a moving battery could ground itself out against something else and cause a fire. This kit includes all of the stock parts - the cross member and nut as well as the drop-down hooking piece and nut for it.
NOTE: These are genuine OEM Mitsubishi parts and may not perfectly fit non-OEM or alternate sized batteries. The width of the top holder piece will accommodate a battery that is 6+7/8-inch or 17.25cm wide.
