If you plan on using the plastic caps then you would need to get the hudy aluminum spool cups so that it will fit. The plastic caps help protect the spool cups. I had SpecR aluminum spool cups and after a few batteries with 4.0T motor they started to get bent out of shape making slop/play even bigger.
SpecR spool cups
Below K-factory ECS with Hudy plastic cap so far no marks on the spool cups. If you plan on running plastic caps use the Hudy ones they are more flexible and easier to install. The plastic ones that came with the K-factory kit were too stiff I broke both trying to install them...basically useless.
