Mini 4WD 8T Plastic Pinion Gear Set (10 pcs.)

The Hobby Hideaway Verdict: An Essential Pit Box Staple! Pinion gears are the unsung heroes of any Mini 4WD machine. They are the direct link between your motor and your drivetrain, transferring all that speed and torque to the track. Over time, they endure a massive amount of stress and are bound to wear out or crack. At Hobby Hideaway, we consider this 10-piece set an absolute must-have for every racer's pit box so a split gear never ends your race day early.

The Backbone of Your Drivetrain The 8-tooth (8T) pinion gear is designed as a tight press-fit directly onto the motor shaft. Because these standard plastic pinions are incredibly lightweight, they allow your motor to spool up rapidly for maximum acceleration. They are strategically designed to be a sacrificial part—meaning if your car takes a harsh impact or the wheels lock up, the plastic pinion will slip or crack before your motor or more expensive internal gears sustain damage.

Key Features & Technical Specs:

• Essential Spares: Includes 10 individual standard 8T plastic pinion gears 

• Universal Compatibility: Fits standard 130-size single-shaft and double-shaft motors across all modern chassis types (MA, MS, AR, FM-A, VZ, Super-II, etc.).

• Smooth Power Transfer: High-quality plastic construction ensures a quiet, low-friction mesh with your counter gears.

• Lightweight Efficiency: Keeps rotational mass low on the motor shaft for snappy acceleration out of corners.

Hobby Hideaway Pro Tip: If your machine suddenly sounds excessively loud, "screechy," or seems to lose top speed for no obvious reason, check your pinion gear immediately! Hairline cracks are common and cause the gear to slip on the motor shaft. When it's time to replace one, we highly recommend using a dedicated pinion puller and press tool. Pushing a gear on by hand or against a hard surface can easily bend your motor shaft, ruining the motor entirely.
