Overview
Replace fragile plastic or worn dogbone driveshafts with the Hot Racing Heavy-Duty CNC Hardened Carbon Steel Center U-Joint CVD Drive Shaft. Designed as a versatile upgrade for a variety of vehicles — including the Tamiya Tractor 620, Hauler models, Tamiya CC01, Tamiya CR01 (front), or custom builds — this telescoping CVD shaft delivers smooth power transfer and rugged steel durability across a 35mm range of suspension travel.
CNC-machined from heavy-duty hardened carbon steel and finished in a clean black coating, this driveshaft is built to handle high-torque applications without bending or twisting. The U-joint splined design transmits power smoothly through any suspension articulation, while the precision shaft splines provide smooth telescoping action with proper grease.
Key Features
- Heavy-duty CNC-machined hardened carbon steel construction
- Black-finished steel for corrosion protection
- U-joint splined star drive design
- Telescoping shaft accommodates 35mm of suspension travel
- Compatible with 5mm output shafts
- M3-threaded mounting holes
Performance Benefits
- Smooth power transfer through full suspension travel
- Hardened steel survives high-torque applications
- Telescoping design accommodates suspension changes
- Long service life under heavy-duty use
- Eliminates plastic dogbone failures
Usage Notes
Maintain U-joint and shaft splines with grease for smooth operation. Apply a removable thread-locker on screws threading into metal. Verify your vehicle's output shafts are 5mm diameter before installation. Operate within the recommended 107mm to 142mm travel range — exceeding 142mm reduces spline engagement to dangerous levels.
