Champions by Design.1:10 scale 2WD off road has been Team Associated’s signature class since the release of the RC10 in 1984. The Team Associated RC10 buggy series has won 13 of the 18 I.F.M.A.R. World Championships contested since the racing class began. In fact, Team Associated has won more 2WD I.F.M.A.R World Championships than all other manufacturers combined!
The RC10B6 Builder’s Support Kit 2 brings Team Associated race-winning technology to Builder’s assembling dirt oval sprint cars, late models, and custom drag cars. The applications are endless. The Builder’s Support Kit has the major sub-assemblies builders need in a value-packed kit, without having to pay for excess 2WD off-road buggy parts.
At the heart of the RC10B6 Builder’s Support Kit is the Laydown, Layback, and Standup transmissions with ball differential; all gearboxes are included. Putting the power down is the next-generation Octalock slipper clutch with Factory Team LCF slipper pads. Along with the easy-access rear differential, the rear end includes standard pivot rear blue aluminum arm mounts, 69mm CVA bones and B7 rear hubs. The kit also includes a set of four 13mm Big Bore shocks, all four with 23mm length bodies for custom build applications. Builders need only select an appropriate application, and they can bolt on the suspension, shocks, hubs, drivetrain, and gearbox from the Builder’s kit. The opportunities are endless to customize your dirt oval or drag car from any of the B6-based third-party specialty manufacturers in the industry.
