Request Stock NotificationThe Team Associated RC8B4e FWB/RWB Chassis (AS81644) gives racers the option to shift weight bias to suit changing track conditions. Developed during 2023, it enables forward or rearward motor and centre differential positions, helping you balance steering response and rear traction on low-grip or bumpy surfaces.
Key Features
- Two motor and centre differential locations: forward (original) for maximum steering, rearward for increased rear grip and a lighter front end.
- New chassis design installs the drivetrain in the reverse orientation from the original kit to provide a positive torque reaction that aids rear grip on power.
- Designed for tuning weight distribution on lower-grip, ungroomed tracks.
Suggested Compatibility
- RC8B4.1e
- RC8B4e
Notes
- To update an RC8B4e to this chassis system, Team Associated notes that AS81644 (chassis) and AS81645 (FWB/RWB adapter and 96.5 mm dogbone set) are needed; instructions are included.
- The original kit’s #81581 104 mm centre dogbone is used with the new parts.
- AS81646 96.5 mm centre dogbone set is available separately for spares (included in AS81645).
Secured by Stripe
The new Team Associated FWB/RWB was in development during 2023 as Team Associated drivers wanted the option to shift weight rearward on lower grip ungroomed tracks.
Now available, racers can tune the RC8B4e's weight bias using two motor and center differential positions with the FWB/RWB chassis and adapter! Forward is the original location for maximum steering, and the rearward location gives more rear grip and lightens the front end for low grip or bumpy conditions.
Customers will need #81644 and #81645 to update their RC8B4e to the new chassis system (instructions are included). The #81581 104mm center dogbone from the original kit is used with the new parts. The AS81646 replacement 96.5mm center dogbone set is sold separately for spare parts (it's included in AS81645).
Also notable, the new chassis design installs the drivetrain in the REVERSE orientation from the original kit, and this provides a positive torque reaction that will aid in rear grip on power.
