SSD RC SCX10 II Pro44 Portal Rear Axle (UPDATED!)
Kit went together with no issues. Unfortunately the rear plastic axle broke after only a few minutes of driving. very dissatisfied with the durability. They pretty much force u into buying the aluminum upgrade. Only have a 27 turn motor.

(Update) emailed SSD about my negative experience and Chris hooked me up with replacement parts to get me going again. So I updated my review from 1 to 4 stars because they stand behind their product.
