This is an RC-scale motor pinion designed for Team Losi Super Baja platforms, supplied by GPM as SSB018T. The part is an 18T pinion made from hardened steel #45 intended for direct motor drive, not for full-vehicle or road vehicle use.
The pinion replaces the Super Baja Rey's original 19T motor gear with an 18T option; changing to 18T affects final gear ratio and can be used for tuning acceleration or top speed tradeoffs on the model. When fitting this pinion to the motor mount you must align and use the hole marked 18T on the mount as described by the original motor mount markings.
Material and fit: the gear is produced in hardened steel #45 for wear resistance under typical RC electric motor loads, and it is meant to engage with the vehicle's spur and existing drive components at the matching gear mesh. Check gear mesh and motor position after installation to avoid premature wear.
Included items in the package are listed here for clarity: motor gear - 1 pcs, 5×5 SST screw - 1 pcs. Verify screw type and length before final assembly and secure the pinion to the motor shaft following standard pinion mounting practice for the Super Baja platform.
