Novak 5123 Mod 1 5mm Steel Pinion 3-Pack (18/19/20)
These hardened gears allow drivers to experiment with gear ratios. In addition to the added flexibility, these three-gear packs save money by giving drivers the ability to purchase a pack of gears, instead of buying individually. These Novak 5mm Mod 1 steel pinion gears are shorter in length to easily fit into all popular brushless 1/8th scale cars and trucks. These gears allow users to take advantage of the lower Kv generated by the HV Sintered Tuning Rotor with 5mm Shaft 14mm. Also, the gearing in your car or truck must be decreased for an overall lower gear ratio.
