12T Motor Gear / 33T Spur Gear (Mod 1.5) - Compatible w/ X-Maxx, XRT

Key Features & Benefits:

• High-Strength 40Cr Steel Construction – Both the pinion and spur gear are precision-machined from hardened 40Cr steel for significantly improved strength, wear resistance, and long-term durability compared to the factory gears.
• Upgraded 3-Point Support Design – Includes a hardened steel cush drive input shaft, 6x13x5 bearing, and CNC-machined 7075 aluminum support mount to create a three-point supported gear system. This provides greater drivetrain stability, reduced gear deflection under load, and smoother power transfer than the stock two-point support design.
