The Yokomo Y2-503GPA plastic bevel gear set provides a lightweight replacement for YD-2 drivers seeking finer control. Molded resin reduces rotating mass compared with metal bevels, lowering gyroscopic resistance for smoother transitions and steadier slides on drift circuits.
Metal gears bring durability but add inertia that can blunt steering response. Plastic gears offer greater agility and reduced spin inertia, though they can show wear faster under high loads. Choose based on your motor power and driving conditions.
Made specifically for the YD-2 platform, the Y2-503GPA fits as a direct replacement. Ensure correct gear mesh, inspect bearings, and perform a bench run to confirm quiet, smooth engagement before track use.
