Re: WCP vs Vex Ball Shifter

Both the WCP DS and the VEXpro ball shifters are good quality.

The output shaft of both gearboxes is made from 7075 Aluminium that is anodised. There shouldn't be any problem with the shaft wearing down when used correctly such as in a WCD. The shifting component either Dog or Ball can wear though.

The VEXpro ball shifters allow encoder attachment while the WCP DS does not. If you are planning to use a WCD this is not a problem as the encoder such as a grayhill or a CTRE mag encoder can be mounted to an outer axle. If necessary a CUI encoder, First choice 2015 and 2016 can be mounted to one of the CIM motor shafts of the WCP DS using this great thing http://www.chiefdelphi.com/forums/sh...WCP+DS+encoder


While the WCP DS is designed especially for use in a WCD. The main difference is the type of shifting, the WCP DS is a dog-shifter while the VEXpro ones use a shifting ball. There have been a lot of discussions on this topic on CD previously.
