Traxxas Extreme Heavy-Duty Upgrade Kit (Green)

The Traxxas Extreme Heavy-Duty Upgrade Kit turns a tough 4X4 into a bash-ready rig that can handle brushless power and aggressive driving. This kit swaps in stronger driveline pieces and reinforced suspension parts so you can send it at the skate park or on high-speed runs without worrying about immediate breakage.

Key Features

• Multiple dynamic color options let you match or customize your truck's look while replacing worn parts in style.
• Maxx Duty driveshafts with 6 mm stub axles deliver improved torque handling for high-power brushless setups.
• Reinforced caster blocks, steering blocks, hub carriers, and shock towers increase impact resistance where stock parts tend to fail.
• Steel wheel hexes provide a firmer, more positive wheel mounting surface under load.
• Oversized sealed bearings reduce drag and keep dirt and moisture out of the drivetrain for longer service life.
• Installation hardware is included so you have the fasteners needed for a direct swap into a compatible chassis.
• Fully compatible with HD suspension arms for a complete heavy-duty setup without extra modification.
• May not work with all sway bars or other accessories; compatibility varies with some aftermarket parts.
