Maybe he meant low gears and Aisin Tranny. 4:10's and the Aisin is the way to go towing heavy. Snoking
I am thinking so.
Although my "Max" trailer weight with the 3.42:1 gears is 17,000 I assure you it has zero issues towing 20,000# behind the truck. Hills,mountains,back roads or anything. Will more heat build up in the 3.42's? Sure it will but if you don't tow 500 miles straight in the mountains they hold up just fine. I like the high gears because when not towing I can bust down some crazy fuel mileage.
65K towing with 68RFE and 3.42's ZERO issues, thats towing a combined 29K. Only negative was starting on a grade you had to ease into it til you got rolling. That said the Aisin and 3.42's are far superior getting the load rolling. Add the 4.10' and it's nite and day difference.
29K combined in pic. 11 HO 3.42's 68RFE.
