WCP SS Gearbox

WCP SS Gearbox

This 2-stage, single speed gearbox is designed from the ground up to be one of the most versatile and easily adaptable gearboxes in the marketplace. Its mounting makes it simple to integrate into any drive train configuration while its parallel plate design and shaft layout allows for easy adaptation to any number of different gear ratios (including the five options we provide).

The WCP engineering team has taken user feedback and incorporated it into an even better version for 2014. The most obvious improvement is the location to mount a 3rd CIM style motor (or gearbox with the same mounting pattern).

As before, the SS has two CIM motor positions to allow for multiple size pinions. There are 4 possible pinion sizes and gear kits, giving a total of 20 gear ratios. All of these can be swapped in without any modifications to the gearbox. This means teams can use any size VEXpro wheel and still have a wide range of desirable gear ratios without any additional sprocket reductions.

WCD Version (217-3422)


The WCP SS includes the option to come in a "West Coast Drive" (or "WCD") configuration. This style features additional space for a set of sprockets or pulleys to be contained within the gearbox assembly itself, bringing them close to the drive frame and making it easy to create a "West Coast"-style cantilevered drivetrain.
