This is a replacement Team Losi Racing 22 2.0 TiCN Hinge Pin Set. This can also be used as an optional upgrade for the first generation 22, 22T and 22SCT vehicles. The Ti-Carbonitride coating has proven to be a very smooth and even more reliable than Ti-Nitride. Ti-Carbonitride coating is used on the front and rear inner hinge pins, threaded kingpins, and threaded outer rear hinge pins.
