Key Features
- MaxxDuty Driveshafts — These massive-diameter driveshafts with heavy-duty U-joints are purpose-built to handle the brutal torque output of the Velineon 540XL brushless motor with complete confidence. The large 6mm axles key into included steel wheel hexes, delivering unmatched strength and durability that standard driveshafts simply cannot match, making them essential for extreme brushless setups.
- Heavy-Duty Caster and Steering Blocks — Crafted from Traxxas's toughest composite material and beefed up with extra material in critical stress areas, these components are engineered to take a pounding. The reinforced construction combined with larger sealed bearings ensures both ultimate durability and precise steering response, even under extreme driving conditions and high-impact bashing.
- Heavy-Duty Axle Carriers — Made from the same advanced composite compound as the caster and steering blocks, these carriers feature additional material precisely where it's needed most. Both the steering blocks and axle carriers incorporate larger bearings for ultimate durability and precision, reducing play and maintaining crisp handling characteristics.
- Heavy-Duty Shock Towers — New heavy-duty shock towers and body mounts are manufactured from Traxxas's toughest composite material. These upgraded shock towers readjust the roll centre to perfectly accommodate the larger MaxxDuty driveshafts, optimising suspension geometry and handling characteristics for maximum performance with the heavier driveline components.
- Steel Wheel Hexes — The inclusion of steel wheel hexes provides exceptional strength at the crucial point where wheels connect to axles, preventing stripping and deformation under extreme torque and impact loads from brushless power systems.
- Oversized Sealed Bearings — Larger sealed bearings throughout the suspension and driveline components provide enhanced load capacity, reduced friction, and better protection against dirt and moisture, extending component lifespan even in challenging driving environments.
- Complete Installation Hardware — Every fastener, shim, and clip needed for installation is included in the box, ensuring you have everything required to complete the upgrade without purchasing additional parts or hardware from your local RC shop.
- HD Suspension Arm Compatibility — The kit works seamlessly with both standard and heavy-duty suspension arms, giving you flexibility in how you configure your truck and allowing for a staged upgrade approach if preferred.
Technical Performance
The Traxxas Extreme Heavy-Duty Upgrade Kit represents a significant engineering upgrade specifically tailored for brushless RC short course trucks running extreme power systems. Every component in this package has been engineered to work in harmony with one another, creating a cohesive system far more effective than individual upgrades. The MaxxDuty driveshaft system, featuring massive-diameter shafts with heavy-duty U-joints, is specifically designed to handle the extraordinary torque output of brushless motors like the Velineon 540XL without flex or failure. The 6mm axles key firmly into steel wheel hexes, eliminating the compliance and potential for stripping that can occur with standard driveline components when subjected to extreme brushless power. The upgraded suspension components—caster blocks, steering blocks, axle carriers, and shock towers—are all manufactured from Traxxas's advanced cold-weather composite material, which provides superior toughness compared to standard plastics whilst maintaining light weight. The strategic addition of material in critical stress areas, combined with oversized sealed bearings throughout, ensures that the entire front end can absorb impacts and handle extreme forces without damage. The roll centre adjustment provided by the new shock towers ensures optimal suspension geometry when running the larger MaxxDuty driveshafts, maintaining precise handling and preventing unwanted geometry changes that would otherwise compromise steering response and cornering performance.
