Overview
Maximize traction, climbing, and wheelie performance on your Traxxas Mini Maxx with the Hot Racing Differential Locker Spool. This precision-machined spool replaces the differential planet gears with a fully locked output, transferring 100% of drivetrain torque equally to both axles for a dramatic boost in straight-line acceleration and off-road climbing ability.
A locked differential is the go-to setup for serious bashers, climbers, and drift drivers who want maximum traction off the line and predictable, consistent power delivery to both wheels. Note that this is recommended for off-road use only — locked differentials reduce on-pavement turning ease.
Key Features
- CNC-machined 6061-T6 aluminum gear hub, blue anodized finish
- S2 spring-steel output shafts for maximum strength
- Cross-pin locker plate design
- Fully assembled — drop-in installation
- Replaces TRA 10782 planet gears for a fully locked diff
Performance Benefits
- Improved acceleration with equal torque to both axles
- Better climbing on technical or steep terrain
- Increased wheelie potential for show or drag use
- Consistent, predictable power delivery
Usage Notes
Recommended for off-road, drag, or climbing use only. Use both case halves; differential pins are not required when running the spool. Apply medium thread-locker on the output set screws during installation. Locked differentials make tight on-pavement turns more difficult — choose this upgrade based on your intended use.
