## Description

Product Identity: This 39-tooth differential gear assembly is a precision RC car part built for 1/10-scale radiosteered car models, featuring a toothed gear gear and a cylindrical housing with contrasting circumferential bands.
Core Function: As a key drivetrain component, this differential gear distributes rotational power between output axles, working with a separate included bevel gear to transfer motion through the drivetrain of compatible RC base units.
Construction Features: This gear assembly is crafted from alloy with silver-colored bearing collars and black forked output, delivering a rigid machined structure for consistent gear meshing.
Compatibility Upside: Designed as a replacement upgrade part, this 39-tooth differential gear assembly works with TT02, XV02, MB01, BT01, and XM01 RC car chassis for straightforward installation.
Performance Upside: This manually operated, non-electric component supports smooth power transfer and constant drivetrain response, helping maintain consistent performance during runs, repairs, and custom 1/10-scale builds.

Whether you are rebuilding a worn drivetrain, assembling a new 1/10-scale kit, or keeping a spare on hand for trackside repairs, this 39-tooth differential gear assembly is a practical RC car part to have in your tool kit. It is sized and shaped for popular 1/10-scale radiosteered car models, with a toothed gear gear and a cylindrical housing marked by contrasting circumferential bands that make it easy to identify. As a central drivetrain component, this differential gear plays a role in how power reaches the tires It works alongside a separate bevel gear included with the assembly to split rotational force between the two output sides, allowing the outer wheel to rotate faster than the inner wheel through corners for more controlled handling and less tire scrub. Built from alloy, this gear assembly combines strength with relatively low weight, so it can stand up to repeated forward motion, braking, and impact loads without adding unnecessary mass to the chassis. Silver-colored bearing collars and black forked output complete the construction, giving you a clean, serviceable design that mates cleanly with axles and bearings on compatible cars. Installation is straightforward on supported base units, including TT02, XV02, MB01, BT01, and XM01 chassis. Because it is supplied as a complete assembly in a bag, you can install it into your car without sourcing individual separately, making it ideal for both planned maintenance and unexpected breakdowns at the trackside in the workshop. Since it is a manually operated, non-electric part, this 39-tooth differential gear assembly focuses purely on dependable mechanical performance. It promotes smoother power transfer and more consistent drivetrain behavior, so your car accelerates predictably, corners with better stability, and holds up reliably run after run.
