Overview
Bulletproof your Arrma Grom Narrow's front drivetrain with the Hot Racing Heavy-Duty Steel Narrow Front CVD Universal Drive Axle Shafts. CNC-machined from heavy-duty steel and pre-assembled with aluminum clamping wheel hexes, these front narrow CVD axles deliver a complete, drop-in upgrade over the factory dog-bone and plastic wheel-shaft setup.
True CVD universal joints maintain constant velocity through the full steering and suspension travel — critical at the front axle where steering angles are at their most extreme. The result is smoother steering response, no more dog-bone bind, and zero broken plastic shafts when bashing or running brushless power.
Key Features
- Heavy-duty CNC-machined steel construction
- True CVD universal-joint design — constant velocity at all steering angles
- Aluminum clamping wheel hexes pre-installed
- Direct replacement for Arrma ARA311229 and ARA311226
- Narrow-width design for the Grom Narrow chassis
Performance Benefits
- Smoother steering through full lock-to-lock
- Eliminates dog-bone bind and vibration
- Slop-free aluminum clamping hex interface
- Handles brushless torque without breaking shafts
Usage Notes
Apply light grease to the CVD pivots during installation to maintain longevity and ensure smooth operation. Apply removable thread-locker on the wheel hex clamping screws. Re-grease pivots periodically as part of routine maintenance.
