This is a set of two optional M2C Racing 4mm Inner Front Captured Hinge Pins, intended for use with the Hot Bodies D8 and D8T 1/8 Vehicles.
These 4mm hinge pins made from hardened 01 Tool Steel, and are threaded on both ends for 3mm nuts. Red Lock Tight is used on the non-lock nut, which is threaded on the front end of the pin. The rear end of the pin uses a standard 3mm lock nut. This design is intended to keep the suspension blocks from spreading during a crash and stripping out the suspension block mounting holes in the bulkhead.
