Default Re: Gears are good...

Orange Crush did the upgrade help your ability to tow?
I have 37s on my H2 and recently purchased a 6000 lb toy hauler.

MPG while towing is crap, I am assuming around 8 mpg. I am considering buying a diesel truck to tow it around, still debating...

You think the 4.56 gears will substantially help my mpg and power while towing? What is the rough cost of something like that?

Thanks!

OrangeCrush is an unknown quantity at this point

Gear are roughly 800 bucks (includes installation kits...)

You will gain roughly 2-3 mpg with gears put back in it.

The ability to tow will definitely increase.

The bigger tires obviously lower your gear ratio. While that may be okay while driving down the highway and it seems like you're turning a lower rpm, then it allows your rpms to be below your powerband of the cam in your engine.... thus no power. (well, less power)

In my case, I had a supercharger. The lower rpms didn't pull so I'd have to step on the gas more.

Stepping on the gas put the supercharger in boost which makes everything run hotter but also eats more gas.

Putting the gears is DEFINITELY worthwhile.

Buying my supercharger will make it even better.

was that $800 for each end, or for all together?

seems kinda low, or maybe i was just expecting it to cost alot more.
i was thinking along the lines of about $1200 per axle.
gears roughly $300

Check this page...

Trail Duty

You'll see the gears for less than 500 bucks pluss install kits and you'll have less than 800 bucks.

Local shop wants about $1400 to replace the gears, bearings and some other miscellaneous stuff. $800 for parts and $600 for labor, is that about right?
