Overview
Solve the rear drivetrain weak link on your Losi Grom Nascar with the Hot Racing Heavy-Duty Narrow Steel Rear CVD Axles. Precision CNC-machined from heavy-duty steel and equipped with aluminum wheel hex hubs, this pre-assembled rear CVD axle set replaces the stock factory CVD dog bones and plastic wheel shafts (ARA311229, ARA311227, ARA810053) with a bulletproof all-metal drivetrain solution sized specifically for the narrow Nascar suspension geometry.
The Nascar suspension setup demands a narrower rear axle than the stock Grom Typhon configuration — and this purpose-built axle set delivers that geometry along with the strength to survive aggressive launches, hard cornering, and brushless-power loads. Pre-assembled and ready to bolt on for an easy, high-impact drivetrain upgrade.
Key Features
- Heavy-duty CNC-machined steel wheel stub shafts
- Aluminum wheel hex hubs
- Universal CVD joint design
- Narrow Nascar-spec geometry
- Pre-assembled — bolt-on installation
- Direct replacement for ARA311229, ARA311227, ARA810053
Performance Benefits
- Bulletproof rear drivetrain
- Smooth power transfer through full suspension travel
- Survives high-torque brushless drivetrains
- Aluminum hex hubs provide secure, slop-free wheel mounting
Usage Notes
Made for Grom Nascar builds using ARA330840 (Rear Arm B set) and ARA330841 (knuckle B set). Light grease is required on the steel CVD u-joints to maintain smooth operation and longevity. Apply removable thread-locker on hex clamp screws during installation.
