Screw up on web site.Or refering to units for gas then diesel etc.Many threads on the subject if you do a G56 search a while back.06 is a G56. 03 through 05 is a Nv5600.The G56 is geared lower in 1st/reverse and 6th.the G56 is a Damiler built unit.Used in Europe for a number of years.The Nv5600 is built by New Venture here in the states.D.C. got a IN HOUSE ALUM.Case unit in 06 G56.

 

I finally got my truck up to 75 mph today and I am only running 1900 RPM's in 6th with the NV5600.

Ah yes, but I also have 3.73's with 37 inch tires.

 

I knew there had to be a catch to be only turning 1900 @ 75. 37" tires and a 4.5 inch lift? Do you have an altimeter?

 

In 05, the HD Tranny is the NV and the Standard is the G56. If you keep it between 55 and 60mph you will see 20+ otherwise at 70 the best I get is 18 MPG or so.

I thought the same thing when I bought mine, must be 4:10 gears. Couldnt find a sticker or any markings anywhere stating the axel ratio. Finally called Dodge and they said it was 3:73. 70 mph turning 2250 rpms. After much research I found the same numbers that 12pak mentioned earlier. That explained why mine was 2250rpm's at 70 and the boss only turns 2000 @ 70 in his 04 3500.

 

Gear Vendors, 70mph, 1500 rpms, 21 mpg, best modification I've done.

 

A buddy of mine in Salt Lake just had a Gear Vendors installed in his truck and he loves it. Said the same thing, 1500 @ 70mph, 1900 @ 95 mph. He went from getting 700 miles out of a tank of fuel to 930 miles out of a tank of fuel.

 

How much did the Gear Vendors OD cost with installation?

From what I could tell from their website the prices range around the 3000.00 range. I have read some info that has been posted on this subject and their are mixed opinions on their product. I am waiting on a reply from my friend to see what he thinks of his after he pulls his trailer from Utah to Arizona. Their website is www.gearwendors.com. I'm sure in the towing section some guys might be able to give first hand experience on this.

 

Might try www.gearvendors.com. No W in "Venders".

Oops! Was trying to do three things at once.

 

i had forgotton, but got the receipt, almost $3800 installed.

 

I don't believe you could choose one over the other. The NV was used up until a point (My NV equipt 05 was built in Jan) then they switched to the G56. As someone said, I think it was a Dodge website error.

They probably used the NV's until they were gone, then switched to the G56 as it had already been used in some MB trucks in Europe. Remember, the Cummins equipt rams are all built in one place, not several plants.

 

Discussed in the past many times.Web site error.You could'nt choose which 6 speed.12Pack is correct.

 

Iv got the 3.73 gears and 4 spd auto on my 05 and with the speedo exactly on 75, the tach shows 2200
