10spd to 13spd(ATTN DRIVELINE GURUS)

[smorgan87]

As i understand the difference in the 14913 and the 18913 is cooling which can easily be upgraded. Id call a tranny shop and ask em if theres any bearing, gear or case differences in the exact model u have and a rtlo18913 or u can use the eaton website and compare the part#s. Also make damn sure u send that drive shaft to a reputable driveline shop to have it shortened balanced and tested. I have a dead truck in the yard because my reputable guy wasnt real great after all.
