Overview
Take your Axial SCX24's crawling performance to the next level with the Hot Racing Front Overdrive Rock Crawler Transmission. CNC-machined from 6061 aluminum and equipped with hardened steel gears and full ball bearings, this transmission upgrade introduces a 2.68 front gear ratio (with stock 3.12 rear ratio) — creating a true front-overdrive setup that pulls the front axle slightly faster than the rear.
Front overdrive is one of the most effective rock-crawling tuning tricks: by overdriving the front axle, the chassis feels more planted on steep climbs, the front wheels actively pull the vehicle up obstacles, and the rear axle is freed up to find traction. The result is a noticeably more capable, more confidence-inspiring SCX24 on any technical line.
Key Features

Performance Benefits
- Front-axle overdrive improves climbing on steep obstacles

Usage Notes
Due to the wide range of SCX24 vehicle variants, additional axle trimming may be required to install. Use a black grease gear lubricant on the gear train during assembly. Recommended for intermediate to advanced builders comfortable with drivetrain modifications.
