This is an RC-scale aluminum wheel set designed for 1.9" crawler use, provided as a 24pcs kit for builders and tuners. The set uses aluminum components that increase durability and add mass compared with typical plastic wheels, and each completed wheel weighs approximately 170g which can function as external ballast to influence low-speed crawling behaviour.
The kit includes metal wheel discs and rim sections along with center caps and flat head M2.5x7 screws for assembly, allowing users to assemble outer and inner rims with the provided hardware. The wheels are intended to mount to 12mm hex hubs commonly found on crawler platforms; users should confirm hex size and hub compatibility before installation.
From a tuning perspective, these wheels serve two roles: a structural replacement for stock wheels and a source of additional rotational mass to help momentum and traction during technical crawling. Installation requires standard hex mounting to a 12mm hex, correct screw torque on the M2.5 fasteners, and routine thread locking where appropriate to prevent loosening during trail use.
Use this wheel set when you need a durable aluminum option for 1.9" crawler builds that use a 12mm hex, and account for the added rim mass when setting suspension and gearing for low-speed control.
