ASC21160 RC18R 18T Pinion

This precision-machined metal pinion gear transfers motor rotation directly to the spur gear for popular micro-scale radio-controlled electric vehicles. Engineered with exact gear pitch dimensions, the component ensures smooth mesh alignment and efficient power transmission across the drivetrain. It integrates seamlessly onto standard motor shafts without requiring custom modifications or special adapter sleeves. The durable alloy construction resists premature tooth wear and stripping under the high-stress loads of competitive racing. Hobbyists can easily swap this gear to fine-tune final drive ratios and adjust top speed parameters for specific track layouts. Elevate your micro platform with reliable factory drivetrain hardware designed for maximum durability.

• Features a precision-cut eighteen-tooth configuration engineered to optimize the balance between explosive acceleration and high-end top speed.

• Constructed from hardened metal alloy selected to withstand high torque loads and resist premature wear over extended operational lifespans.

• Designed with exact internal bore tolerances for a secure press-fit and set-screw alignment on standard micro motor shafts.

• Engineered with specialized gear tooth profiles that minimize mechanical friction and reduce operating noise during high-RPM power delivery.

• Fully compatible with Team Associated RC18R, RC18T, and related miniature platform transmission layouts.

• Packaged as a single replacement gear ready to install during routine drivetrain maintenance or gear ratio tuning sessions.

• Works seamlessly with standard stock and upgraded aftermarket spur gears to provide reliable power transfer across the entire drivetrain.
