Overview
Step up your Axial SCX24's drivetrain durability with the Hot Racing 0.5M Spur Gear Conversion. This complete pinion-and-spur conversion replaces the smaller-pitch stock gears with a 0.5 mod (Mod 0.5) tooth profile, dramatically increasing tooth strength and engagement area for the abuse of added chassis weight, larger tires, or technical terrain.
The kit pairs an 8-tooth CNC-machined nylon pinion with a 32-tooth CNC aluminum spur gear — the nylon pinion provides quiet operation and shock absorption while the aluminum spur delivers serious strength. A smart, balanced upgrade for SCX24 drivers who want maximum drivetrain durability.
Key Features
- CNC-machined nylon pinion + CNC-machined aluminum spur
- 0.5 Mod (M05) tooth pitch for greatly increased strength
- 8-tooth pinion / 32-tooth spur gear ratio
- Replacement nylon pinion available: Hot Racing HRASXTF08M05
- Designed specifically for SCX24 drivetrain geometry
Performance Benefits
- Larger tooth pitch = dramatically increased gear durability
- Less risk of stripping under heavy load or impact
- Nylon pinion absorbs shock and runs quietly
- Aluminum spur outlasts plastic stock spurs by a wide margin
- Ideal for weighted chassis and technical terrain
Usage Notes
Verify gear mesh by spinning the drivetrain by hand after installation — there should be a small amount of backlash with no binding. Apply medium thread-locker on motor pinion screw. Most beneficial when paired with a brass-weighted chassis or upgraded high-torque motor.
Technical Specs
- Pinion: CNC nylon, 8 teeth, 0.5 Mod
- Spur: CNC aluminum, 32 teeth, 0.5 Mod
- Gear Pitch: 0.5 Mod (M05)
- Replacement Pinion: HRASXTF08M05

Summary
The Hot Racing 0.5M Spur Gear Conversion is one of the smartest drivetrain upgrades for any serious Axial SCX24 build. More strength, less stripping, and quiet operation — exactly what a heavily upgraded micro crawler needs.
