For hobbyists aiming to reduce wear and keep motors running longer, the GPM 45CR Steel Motor Gear is a straightforward swap. It uses a 26-tooth profile with a 48 pitch and a 0.5mm module for a stronger tooth form than typical stock gears. The motor tooth diameter is 5mm, so it fits motors matching that spec. The rounded motor gear hole and black-hardened surface treatment help maintain efficient power transfer and resist abrasion.
