The Yokomo Y2-500GSAA plastic bevel gear differential unit is a direct-fit upgrade for the YD-2SX chassis that balances light weight and strength by pairing a resin bevel gear with an aluminum drive cup. It arrives pre-assembled for quick installation and includes #10000 silicone oil so you can fine tune traction and handling for different track surfaces.
An integral resin protector around the universal joint reduces contact with the aluminum drive cup and slows wear, extending service life. The tighter internal clearances sharpen throttle response so drivers get more immediate power delivery and better control during acceleration and corner exits.
