Introducing our high-performance MOD 1 Castle Creations Pinions, expertly crafted from hardened steel and equipped with the largest Allen head set screw available. These pinions are specifically designed for use in 1:8 scale buggy and truggy conversions, offering exceptional performance and reliability.
Please note that these pinions are not intended for use with the 1721 series motor, which features an 8mm shaft. For compatibility with such motors, we recommend checking out our new MOD1 8MM BORE offerings in our Pinion Gears collection.
Choose from a range of tooth counts to suit your needs, including 11T, 13T, 15T, 17T, 19T, 21T, and 23T. Our pinions feature a 5mm bore and come complete with a 4mm set screw, which can be securely fastened to the motor shaft using a 1.5mm hex wrench. To ensure a firm and reliable connection, we recommend applying a small drop of blue Loctite, a thread adhesive, to the set screw.
