New from HPI Racing is a Heavy Duty Idle Gear for the transmission of the Baja 5B. This 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. Recommended for heavy duty applications in conjunction with the following parts: 86481 Heavy Duty Diff Gear 48 Tooth, 86487 Heavy Duty Drive Gear 20 Tooth. HPI part # 86485.
