This is an optional Serpent 4° C-Hub Set, and is intended for use with the Serpent S411 and S411 FF 1/10 touring cars. These parts are molded from medium density nylon, making them stiffer than the stock parts, but not as rigid as the hard compound, providing you with an "in-between" tuning option when the hard compound is too stiff.
