Sold Out

The Team Associated RC8B4 Team 1/8 4WD Off-Road Nitro Buggy Kit is designed to push the limits of off road racing. This buggy has been given a huge overhaul and features updated gearboxes, front upper and lower arm design, rear arm design, chassis braces, rear hub design and fuel tank design for peak performance. The front-end geometry has also received updates allowing for increased stability and more consistent steering through the entire steering throw. All of these features come together for a buggy that is ready to dominate the track.

Front and Rear Gearbox
The front and rear gearboxes have received crucial updates. The front gearbox features a 3.5° incline allowing for a straightened driveshaft, increasing drivetrain efficiency. The rear gearbox uses a 0° pinion angle, maintaining this straightened driveshaft system. Both gearboxes use oversized bearing for longer bearing lifespan. 

Front Suspension Arms
The front upper and lower suspension arms have been designed to accommodate a wide range of flex and stiffness options. Optional inserts have been made to provide extreme fine tuning and will work with the upper or lower arm. The lower arm features a one-piece anti-roll bar link mounts that are in-line with the anti-roll bar for simplified assembly and operation.

Rear Suspension Arms
The rear arms have been designed for optimum flex and stiffness with no inserts. However, optional inserts may be used for fine tuning. The rear arms also feature a one-piece anti-roll bar link is mounted in-line with the anti-roll bar with a BHCS instead of a shock pin for simplified assembly.
