Um, lower gears (4.10) would make that smaller engine work harder to get up to speed. Granted at like 70MPH you should keep speed easier, but as far as more MPG's, I'm gonna agree with Dad.

Higher gears (3.55) would help...

I threw the numbers in there to demonstrate a lower gear as opposed to a lower number....for clarification.

Anyone using the direct replacement Brembo set? They are not slotted&drilled, but come with a great reputation.
i've had mine on for 5 months and still going strong, actually avoided an accident, and i think if i had the oem brakes they would have faded. The car in front of me slammed on her brakes (for a stupid raccoon witch she still hit) doing 80 km/h (55 mp/h) and i was towing my car on a trailer without trailer brakes and i was able to slow the truck enough to get on the shoulder, man did she get a talk from me

just make sure you use brakemotive they are made and shipped from Detroit

I think you'll have to explain that one a little better. Do you mean that the engine would work harder to get "up to speed" with 4.10 gears than with 3.55??

I don't think so - numerically higher gear ratios allow a greater multiplication of engine torque at the expense of higher RPM at a given speed. An identical truck with 4.10 gears vs one with 3.55 will accelerate a little more quickly and will get up to speed more easily.

i agree, but you also can't go up too high, 4.10 is a great ratio for out stock trucks

I agree - it could be silly to go to, say, a 4.56 ratio for a highway cruiser. But if you're hauling loads in hilly country, off-roading, or if you're turning big tires, you need gears with more grunt.

For me, 4.10's will probably be what I settle on. These 3.55's I have now are OK unloaded on the road, but I know I would be happier towing with more gear in the diffy(s). If I were going to 35+ inch tires, I would seriously consider 4.56's.

I cleaned up all the parts as needed and I was debating on doing a little painting but after a full day of work then doing this I said screw it! I just care how my truck drives. I do recommend doing this upgrade over the OEM parts as of right now. We will see how it works out long term soon enough.
Are the holes chamfered? It looked from the pictures that they were not. The only potential issue I see is cracking if they are just drilled straight through.
