HPI Racing idle 30 tooth gear is precision machined from high carbon steel. With a smoother finish to the teeth and more precise roundness, this gear has less friction for quieter running, increased efficiency and longer life than the stock gear. A thinner profile provides weight savings over the stock gear for quicker acceleration and decreased overall vehicle weight.
This is a direct replacement part for the 86484 stock gear on the Baja 5B. Instructions are included.
