  • Description
  • Specifications
  • Documentation
  • This accessory for blue Sport gearboxes is an easy-to-use device that adds an extra 4:1 overall ratio to the input of any blue Sport gearbox. Because every Sport gearbox uses a 4:1 ratio as it’s input stage, this makes for a simple addition to reduce the speed and increase the torque of any blue sport gearbox. Simply install this device between your desired input motor (such as a RedLine, CIM, Falcon or Dual Motor Input,) and the body of the gearbox, and you’re good to go. For example, you can turn a 4:1 gearbox that you already have into a 16:1 gearbox with this accessory.

    Product Note: It is possible to exceed the maximum rated output torque when using this product with high powered motors and higher ratio configurations of the blue Sport gearboxes. Please carefully consider these load ratings when choosing to use this 4:1 add-on stage in these configurations.

    Each add-on stage comes with two 10-32 Socket Head Cap Screws used to mount the motor block.

Went on easy and worked great.

Went on easy and worked great.

SW from GOULDS
Great product

These have been a great addition to the gear boxes we bought previously from Andy Mark. They fit together perfectly and being able to create gear reduction by stacking is quite helpful.

CS from EAU CLAIRE
Good fit. With shorter screws.

It fit and worked great. The only issue that we had was that we had to shorten the original gearbox screws as they were too long with the way the gear box added on with blind holes.
I do like that these gearboxes are an all metal construction.
