Question: are they a direct fit for the xrt and are the tooth count the same as stock
Share what you knowDanielStaffAnswer:Hi John, Yes, these will bolt straight into the XRT without modification; however, the stock tooth count is 35T with an 11T input gear. This is close enough that you shouldn't see much speed or acceleration difference; however, with the GPM kit, it is a spiral-cut gear and will require accurate shimming. If you wish to install this and aren't sure on anything, reach out to our friendly customer service team and ask anything you want to know.
