Overview
Boost the front-end speed and gear-ratio flexibility of your Axial Capra UTB with the Hot Racing Overdrive Portal Gear Set. CNC-machined from 4140 case-hardened steel, this 13T drive / 22T output overdrive gear set is engineered to replace the stock Axial AXI232007 portal gears with a higher gear ratio that increases front-axle wheel speed relative to the rear — exactly what's needed to combat understeer and improve agility on technical scale lines.
Overdriving the front axle is a proven scale-crawler tuning technique that improves steering response, helps the front wheels pull through turns, and balances the drivetrain torque distribution. Laser-marked silver rings make ratio identification easy at the workbench.
Key Features
- CNC-machined 4140 case-hardened steel construction
- 13T drive gear and 22T output gear (overdrive ratio)
- Laser-marked silver ring for easy ratio identification
- Direct fitment in place of Axial AXI232007 stock portal gears
- Different gear ratio than AXI232007 — overdrive specification
Performance Benefits
- Higher front-axle wheel speed for reduced understeer
- Improved steering response on technical lines
- Case-hardened steel resists wear from rocky terrain abuse
- Better drivetrain torque balance
Usage Notes
Install only in the front portal axles for proper overdrive function — installing in both front and rear cancels the overdrive effect. Apply medium thread-locker on case bolts and grease the gear teeth thoroughly during reassembly. Verify gear mesh and articulation before driving.
