The new Exotek B64 Center Spool greatly reduces the rotating mass for that extra boost in performance you need for the 13.5t and 17.5t spec racing classes. It weights just 18 grams, a huge improvement over the 42 grams of the stock diff. The B64 spool kit includes a machined 75t spur gear, a lightweight aluminum spool, and coated steel outdrive cups. The outdrives are compatible with the stock steel center dogbones or the super lightweight MPI puck bone system.
