Gear Vendor/Gear splitter

Or maybe an Eaton 10 speed conversion swap?

I bet its very expensive?
But how cool would this be!

I've pretty much sold all the other toys I use to through money at so........?

Problem with them is they don't like lots of torque run through them backwards. So it you have an exhaust brake you shouldn't use them.

I had one installed on a 1998 coach with a 460 and a 3-speed transmission. I really liked having 6 speeds and especially being able to run in 2nd/over up hills; plus I could cruise at a faster speed and lower rpm's on flat ground. I sold the coach a couple of years later so I don't know how well they hold up over time. To me, it was worth the money. I think it was about $3000 installed, but that was about 15 years ago.

I have a Mitchell gear splitter but have yet to put it in my old Dodge. It is a modern Brownie Box basically being fully synchronized and made of aluminum. This particular one is 6% under and 18% Over.

Can't wait to have 10spds forward and 2 in reverse!

Having a old Cummins I was seriously considering a Fuller RTOO6610 but they are super hard to find and pretty expensive even when used with hundreds of thousands of miles on them.

With the Mitchell I will use the stock transmission which is easy to rebuild at home if needed some day.

I could think of better ways to spend 3 grand on the truck, but they're kinda cool if you like driving a semi!

You will NEVER make up the cost in fuel savings.

Well I am a class A truck driver, yet I don't drive big rigs very often.
Yet my truck totally reminds me of a big rig.

Interesting thought?

But I'm thinking with 10 gears an exhaust brake may not be as needed being you have more gears to play with vs that gap in between where the EB comes in so helpful.

But I'm assuming the EB would be less expensive?

For me it would be more about control than MPG's.
Going up & down grades would allow you to stay better in your power band.
