Losi LOS3664 Motor Mount Insert 16.5/17.5

This motor mount insert set is designed for the 5IVE-TE 3.0, providing the mounting slugs used to properly position the motor relative to a 67-tooth spur gear. The set includes two insert sizes, 16.5mm and 17.5mm, letting owners fine-tune motor spacing to dial in correct gear mesh for their specific pinion and spur combination. Each insert is machined from 6061-T6 aluminum, a lightweight yet strong alloy that resists the vibration and heat generated by high-power brushless setups while holding its shape under repeated use. Properly matched motor mount inserts are essential for maintaining consistent gear mesh, which reduces drivetrain wear, prevents gear stripping, and cuts down on unwanted noise and friction that can rob efficiency from the powertrain. The set includes four mounting inserts along with the hardware needed for installation, making it a complete, ready-to-install package rather than requiring separately sourced fasteners. Because these inserts are built specifically for the 5IVE-TE 3.0 motor mount, they function as a precise, direct-fit upgrade for owners chasing tighter gear mesh tolerances.
