Overview
Eliminate the most common failure point on your Arrma Grom's drivetrain with the Hot Racing Heavy-Duty Steel Universal Front CVD Axles. Precision CNC-machined from heavy-duty steel and equipped with aluminum wheel clamp hex hubs, this pre-assembled front CVD axle set replaces the flexy stock CVD dog bones and plastic wheel shafts (Arrma ARA311179 / ARA311178) with a bulletproof, all-metal drivetrain solution.
For high-power Grom builds running brushless motors, hard-launch driving, or aggressive bashing, the steel CVD upgrade is essentially a must — stock components simply can't survive the loads modern brushless drivetrains generate. Pre-assembled and ready to bolt on, this is one of the easiest, most impactful drivetrain upgrades available for the Grom platform.
Key Features
- Heavy-duty CNC-machined steel wheel stub shafts
- Aluminum wheel clamp hex hubs
- Universal CVD joint design
- Pre-assembled — bolt-on installation
- Direct replacement for Arrma ARA311179 and ARA311178
Performance Benefits
- Bulletproof front drivetrain
- Smooth power transfer through full steering range
- Survives high-torque brushless drivetrains
- Aluminum hex hubs provide secure, slop-free wheel mounting
Usage Notes
Light grease is required on the steel CVD u-joints to maintain smooth operation and longevity. Inspect and re-grease periodically as part of regular drivetrain maintenance. Apply removable thread-locker on hex clamp screws during installation.
