Single Speed kit. Designed to be a direct bolt on conversion for Kyosho InfernoGT and GT2, Ofna DM1 and GTP and GTPe cars. Unit is precision machined to 6mm or 8mm and installs directly onto stock 2 speed shaft(must remove 2 speed components) or replaces stock single speed adapter.  Includes Aluminum cnc machined adapter and spur gear(Delrin cnc machined  32t/40t/46t mod1 or Traxxas Revo spur gears available).

8mm versions fit Ofna DM1 and ultra series, including the Dirt Oval and GTP road car. 6mm versions fit Kyosho.

Note - The Revo spur adapter is different than the 40t/46t mod1 spur adapter, which is different than the 32t mod1 spur adapter(all 3 adapters are shown in the picture). We do not include the spur gear with the Revo-style adapters.

If converting a car with a center differential, you will need our spool shaft to install this item.
