1:10 Scale Radio-Controlled Electric Sprint Cars
B3 Gearbox Sprint Car
This car is built using the Associated B3 front and rear suspension, and the Stealth 2.4:1 ratio gearbox. If you have a B3 buggy you can convert it to a mid-motor Sprint Car using this conversion kit.

The stock B3 conversion kit contains the following parts:
Lightweight composite chassis with recessed Stealth 2.4:1 gearbox mounting.
Mid-Motor location for optimal weight distribution
Aluminum rear bulkhead
Composite rear suspension tower with adjustable height for long or short shocks
Stand-up servo mounts
Aluminum roll cage with welded rear bumper
Aluminum side nerf bars

Complete body including hood, side panels, small authentic-appearing tail tank
Fully adjustable top wing with aluminum center section, Lexan side panels and mount
Adjustable front wing with aluminum center section, Lexan side panels and mount

The stock B3 conversion kit utilizes the entire Associated front plate, suspension and steering. The front plate bolts directly to the sprint car's composite chassis.
