Two Speed Gearboxes

WCP Flipped Gearbox (Dog Shifter, 3 Stages) (Product Page)

Sometimes you just need to use 3 motors on each side of the drivetrain, but the available options either don't provide the reduction you're looking for, or aren't designed for the tried and true West Coast Drive mounting style. After having this problem ourselves, we decided to solve it with the WCP Flipped Gearbox. Add a WCP Bearing Block and you'll be good to go. We made the WCP Flipped Gearbox so that you can make any drivetrain you want.

• Accepts 3 CIMs, Mini CIMs, Kraken X60s, or any other 2" bolt circle with a maximum diameter of 2.5" (~64mm)

• Over 440 different gear ratio options

• Interchangeable with your other COTS WCD gearboxes
