Team Associated ASC81639 Rear Suspension Arms Medium

These medium compound rear suspension arms serve the RC8B4.1 buggy as both a replacement part and a tuning option.

The rear arms hold the rear hubs and drive axles, take the load from landings and rough track sections, and provide the lower shock mounting point, making them one of the hardest working components on the car. The medium compound sits between the soft and firm options, offering a balanced amount of flex that suits a wide range of surfaces without committing the setup toward maximum rear grip or maximum rigidity. That makes it a sensible baseline choice for most track conditions.

This set fits the RC8B4.1 and RC8B4.1e, installing on the stock hinge pins in the original locations with no modification needed. Use them to replace arms cracked or bent in a crash, to refresh arms fatigued over a season, or to move away from a softer or stiffer compound when track conditions change. Carrying a spare set keeps a broken arm from ending your race day early.
