Tmass,
You are converting from single to double row? Do you mean the "single Row Pro " from LN? Gen 2 Single Row Pro IMS Retrofit
In the cutaway photo you'll notice that it is not the same as a conventional double row bearing. It has fewer balls and the races are staggered because of the space limitation.
Still way better than the OEM single row.
That is correct LN Single Row Pro IMS Retrofit Kit being installed over the next 2 days along with new oil gasket and front underbody panel and oil change. $2104 includ. tax
