TFX Racer Pro Packs

TFX Racer Pro Packs contain all the parts necessary to modify a 16 ohm TFX to find the best gearing and tire size best suits your track and driving skills.  Each Kit contains one assembled and ready-to-be-oiled TFX chassis with a 16 ohm armature, 15  tooth crown and an installed guide pin.  Also included are 16, 17, 18 and 19 tooth Rear Axle Assemblies.  All Rear Axle Assemblies equipped with .352" tires.  A set of .360" front tires, .366" rear tires and .378" tires are included to allow the chassis to be raised to handle home plastic or rough tracks.  1-72  and S2-56 flathead screws are included to allow the TFX to mate with any resin or plastic body. Aurora and Model Motoring cars will use the S2-56 screw.  AW, JL and resin   cast bodies may use either screw depending on their screw hole size. Most racing resin cast bodies will use a 1-72 screw.  AW/JL bodies have a hole in between sizes so either screw may fit best.  A 1-72 screw will fit most.  Two extra guide pins are also included in the kits. Idler Gear must be removed to properly oil the idler gear post. DO NOT SKIP THIS STEP.
