Tired of fixing lousy engineering.
Hey guys-n-gals,
Just wanted to chat and see what opinions are (especially experienced opinions) about rear gear ratios on these 1500's. Obviously this applies to the 4WD trucks but that requires swapping the gears in both diffs.
When the bearings went bad in my truck (1999 C1500 Suburban), I pulled the factory 3.42 and put in a Motive 4.10 and Eaton Truetrac Posi (which is awesome, by the way).
I almost wish that I had put in a 4.56.
So far, I've not found any discernible loss in mileage. Neither have I bothered to calculate it, but I still use the same 5 gallons of gas per week making my short commute to work. We also make a repeated "long haul" about 4 times a year to see family, and I still use around 35 gallons of gas.
I monitor my trans temp using a bluetooth OBD2 dongle paired with a smartphone, and I can even read my torque converter slip RPM. So far, whether towing or not, I am generally able to tow in 4th gear, verify that the TCC isn't slipping, and see my trans fluid temp is staying under 190 (usually 160 or less if not towing).
I run 31X10.5 tires on this truck, and honestly they look WAY better than the short little tires that came stock on it. These are the 5-bolt 15" stock wheels.
The only thing we tow is our camper, which weighs around 2,000lbs fully loaded with gear (1600 empty). It does tow a little better with the 4.10's, especially low speed and around town. Honestly the change when towing wasn't as much as I thought it would be.
Anyone here running 4.56's on a daily driver?
