This pinion gear is made up of hard anodized chrome metal, its 48-53HRC certified. You'll get the vigor you may need the vehicle through changing pinion gear. With comparable outside gear, you are able to increase your pinion gear (within allowable range) for different torque and price. (the reduced the T count, greater the torque; the greater number of expensive the T count, the faster the rate.)
Specification: Bore Diameter: 5mm / Modulus: 1.0mm / metal Pinion: 40CR
Applications: the favourite 1/8th off road (buggy and truggy)
