I have the tow package and as I understand it...we have 3.36 gearing (can anybody confirm this?).

I'm wondering about regearing to get better towing capabilities and a happier diff...any thoughts.

Anybody do this yet?

COOL!  4.10's are a possibility?   COME ON AFTERMARKET!

The rear dif number is only the final drive. How you get there is important. Seeing as the first three gears are spaced with lower output to begin with you don't need a a lower rear gear multiplier. You cannot compare final drive numbers on a four speed to those on a five. If I recall, the 5 is an overdrive, the 4 is a 1:1 and the lower three are collectively lower than what you'd find on a lot of trucks. I do not recall what the math crossed over to- if it were 4.10 or what. Sorry. A bit more time and numbers and we could run it all over again I'm sure. With the motor turining more rpm than most other trucks you create a helluva lot of torque with the lower three gearrs IF you crank it up more. The dif is only the final number but does not dictate the only result. * If you need to improve towing you simply need to run the motor a bit higher. That's where the power is in this one. This truck runs strong in the 4-5k range all day long. (passes everything but the gas station) If you feel like a dog, drop down a gear. I run (yes with cruise on) pulling a modest 2500lb race car trailer at 70-75 up and down hill doing nothing but popping from gear to gear as required.

Hey Todd,

That's great and all, but you should be concerned with the rear diff.  That's where this truck is failing for those who tow.  The 3.36 final is doesn't offer enough reduction for a vehicle that tows.  The by product is heat...and hence the reason for the cooling fins for 05.

The cooling fins are to help a symptom, not fix the rear problem.

4.10's would make the truck slow, poorer gas mileage...but improve towing as far as the rear diff is concerned (specifically heat production)...not to mention making hills THAT much easier to go up.

Since you were involved w/ this truck...do you have access to ring and pinions for it (the 4.1....I'd be willing to be the Ginnie pig).

Thanks guys i understand it better now.Now i understand the tow mode button also increases the shift points in transmission and the manuel says fuel consumtion suffers. Anybody checked this?
