Team Associated RC8T4 Truggy Team Kit (with Gearbox Upgrade)

Kit
This vehicle is supplied as a kit and must be completely assembled by the user. The kit does not include an engine, exhaust pipe and header, transponder, servos, receiver, wheels, or tires. Assembly and painting required.

Overview

The Team Associated RC8T4 Gearbox Upgrade redefines durability for 1:8-scale truck racing—the most demanding segment in R/C. The new 40/9 ring and pinion gears, developed by Area 51, feature larger, more robust teeth for maximum engagement and no skipping under extreme loads. The redesigned RC8B4 gearboxes use highly rigid polymer for precise bearing and screw mounting, increasing drivetrain reliability and efficiency. Proven in competition, this upgrade powered Spencer Rivkin to victory at the 2024 ROAR Electric Truck Nationals, delivering unmatched strength and performance.

Features

• Innovative front-end geometry combined with 8° caster steering blocks and new, wider upper arms for a more balanced steering feel and predictable handling in all conditions.
• New front and rear gearbox housings increase drivetrain efficiency by reducing phase shift and vibration. Larger ball bearings extend the service life of the ring and pinion gears.
• New front shock tower designed to match the revised suspension geometry and accommodate various truggy bodies.
• Ball cups and sway bar links made from a new, more durable material.
• New +2 mm and +4 mm longer shock rod ends for more precise adjustment of rebound and compression travel.
• Redesigned front upper arms with inserts for improved fit and performance.
• Wing mount with angle-adjustment plates, increased stability, aerodynamic design, and more room for precise adjustment of the shock position.
  Wing with vertical fins and a higher lip for increased downforce and straight-line stability, with selectively reinforced material thickness to prevent flex fatigue.
• New rear chassis brace with a central mount on the gearbox housing for reduced material fatigue, centralized shear forces, and a longer rear drivetrain service life. Three chassis-flex settings available
  New laterally symmetrical rear hub carriers with axle inserts for roll-center adjustment
• Large-capacity fuel tank with ergonomic lid, easy-to-read fill-level markings, and 1, 2, and 3 cm³ inserts for volume adjustment during official races
• New front and rear gearbox housings with larger ball bearings extend the service life of the ring and pinion gears. The front gearbox features a 3.5°-angled pinion gear for a straight center driveshaft, improving drivetrain efficiency and reducing phase shift and vibration. The rear gearbox has a 0° pinion angle with a centrally mounted chassis-brace connection
