The GPM 20Cr steel motor gear is produced from hardened 20Cr material and given a black hardening treatment to enhance surface durability and reduce wear. Available in 14T through 20T sizes with a module of 1.0mm, it is made to pair with motors that use a 5mm tooth diameter. The part uses a round motor bore retained by two 4x4 set screws for secure installation. It fits compatible 1/8-scale ARRMA and TRAXXAS setups when the gear specifications match, so check your motor gear dimensions before purchase.
