Overview
The Hot Racing Aluminum Center One-Way Differential is a precision race-tuning upgrade for the Traxxas Slash 4x4, Stampede 4x4, Rally VXL, and Telluride 4x4 (center gear differential models only). The center one-way drives both front and rear wheels under forward acceleration but allows the front wheels to "freewheel" under braking, deceleration, and reversing — letting the chassis rotate ("whip") into corners far more aggressively than a traditional center diff.
The one-way center diff is a serious racing tool: ideal for tight tracks where maximum off-power steering and rapid corner rotation are critical. Combined with proper driving technique, it transforms cornering ability and lap times on the right track.
Key Features
- CNC-machined aluminum construction
- One-way bearing (6x10mm) drives front under power, free-wheels under braking
- Maintains front gear differential action
- Direct replacement for stock center diff (gear-diff configuration)
- Includes mounting hardware
Performance Benefits
- Maximum off-power steering on tight tracks
- Allows aggressive chassis rotation under braking
- Faster cornering ability with proper technique
- Race-proven setup for high-grip carpet and asphalt
Usage Notes
Important: Requires the center-gear-differential configuration of the vehicle. NOT compatible with slipper-clutch versions. Requires a spur gear designed for center gear differential — Hot Racing SSLF2 series spur gears recommended (slipper-style spurs will not work). Practice braking technique before racing competitively; one-way diffs change vehicle feel significantly.
