Technical Performance
This extreme heavy-duty upgrade kit represents the pinnacle of driveline and suspension engineering for 1/10 scale 4WD short course trucks in the brushless RC category. The kit is specifically engineered for extreme brushless power systems, making it the perfect complement to high-output motors like the Velineon 540XL that deliver devastating torque to the drivetrain. The MaxxDuty driveshafts feature massive diameter construction with heavy-duty U-joints that absorb and transmit extreme torque without flexing or failing, whilst the large 6mm steel axles provide uncompromising strength and durability. Every component, from the caster blocks and steering blocks through to the axle carriers and shock towers, is manufactured from Traxxas's toughest cold-weather composite material—specifically formulated to maintain strength and reliability in variable UK weather conditions. The strategic use of larger sealed bearings throughout the package ensures smooth operation under high stress and extends component lifespan significantly. The redesigned shock towers cleverly readjust the roll centre geometry to perfectly accommodate the larger MaxxDuty driveshafts, maintaining optimal suspension kinematics and handling characteristics. This is not a collection of random upgrades but a cohesively engineered system where every part works in harmony with every other part, delivering measured performance gains and dramatically improved durability over standard components.
