Overview
The Team Associated RC8T4e Team Competition Kit with Gearbox Upgrade represents the pinnacle of 1/8 scale electric truggy engineering. Developed by Associated Electrics' Area 51 design team, this professional-level platform is built to handle the extreme demands of 1/8 scale truck racing—the highest stress discipline in the RC hobby. The included gearbox upgrade absolutely bulletproofs the RC8T4 drivetrain, featuring a completely redesigned 40/9 ring and pinion with massive teeth for more engagement and skip-free performance.
Team Associated driver Spencer Rivkin used this upgraded platform to win the 2024 ROAR Electric Truck National Title, pushing his truck to the maximum without ever worrying about drivetrain durability. The RC8T4e combines the stability and presence of a truggy with the efficiency and responsiveness of electric power, making it ideal for high-grip tracks, large jumps, and demanding race conditions.

Drivetrain Technology
The RC8T4e's front gearbox features a 3.5° inclined pinion gear angle to straighten the center driveshaft, reducing phasing and vibration. The rear gearbox uses a 0° pinion gear angle with center-mounted rear chassis brace. Both gearboxes feature larger bearing sizes for extended component life and the updated high-stiffness polymer ensures the tightest possible screw and bearing fit.
