Overview
Replace worn or damaged factory diff outdrives with the Hot Racing CNC Aluminum CVD Driveshaft Diff Outdrives — a precision-machined drivetrain rebuild kit for the Arrma 4S V2 platform. CNC-machined from solid aluminum, these outdrives are direct replacements for Arrma ARA311149 and ARA311150 components and are designed to handle the punishing torque of 4S brushless drivetrains.
By keeping your CVD driveshaft connection tight and rotating true, these outdrives restore drivetrain efficiency and prevent the slop and gear wear that follows worn-out factory parts. A smart drivetrain refresh for any high-mile 4S V2 vehicle.
Key Features
- CNC-machined aluminum construction
- Direct replacement for Arrma ARA311149 / ARA311150
- Designed for CVD driveshaft systems
- Set screws included for secure mounting
- Precision-machined for smooth, true rotation
Performance Benefits
- Restores tight, slop-free CVD engagement
- Prevents drivetrain wear caused by worn outdrives
- Strong enough to handle 4S brushless torque
- Long service life with proper maintenance
Usage Notes
Apply removable thread-locker to set screws during installation. Inspect the differential and CVD driveshafts for additional wear during install — replace any worn components at the same time for a complete drivetrain refresh. Does NOT work with TFFP288RC.
