My rear end,342


Recommended Posts

Okay I need help.I just picked up my Chebey 900 crew yesterday.Traded my Honda Ridgeline because of driveline issues and poor milage.Being a GM retiree I felt criminal in the Honda.So far the 900 is more than I thought.I've got the flex fuel 5.3 with the 342 for milage with 20" Texas Edition wheels.

Now being a farm hick I know to pull I need a .410 or at least a .373 rear end.I am going to pull occasionaly a 3000# cargo trailer but usually I'll use the truck as a car.What I'm looking for here are some words of confidence that the truck will give me good milage and pull my trailer when I need to.This looks like a great forum and I feel like I'm home again.

I'm with Balth on this one. I've got 3.42 rear gears in my '76 Chevy and haven't had problem one out of it that wasn't my own fault. Like running it low on gear oil and burning up the bearings in the original. But I replaced the differential with an identical one and I can still tow, haul, carry, or tote any load that I'm required to.
