It's been a while since I chimed in here. I stopped by my gear shop last week and AAM still has a backorder on the gears. I am beginning to wonder if they are even available at this point. I am going to contact my AAM fellow again to see what he might say. I am still going to jump on this gear...

Please help me understand something. In Roger's pics, it appears the supply line is coming from the exhaust side. I thought from viewing Frantz's site that the supply oil comes from removing a plug from near the oil filter. What am I getting wrong? And on Cal's truck, is that TWO bypass oil...

My experience has been that fuel mileage really came in at 20K and has gotten a bit better now at 32K. Again, my experience, slow down to get fuel mileage. Back in 1973 when I got my drivers license, they lowered the national speed limit to 55 MPH. I learned to drive that speed and did for...

I just set a record with my truck..... constant 60 MPH, Dallas to Tulsa, very little wind..... 26. 7 MPG. I used to experience 24. 4 and 24. 6 on the same road, filling up at the same spots and same pumps. Only difference from last summer to this is Rokktech timing sensor, max. advance and...

Cummings? Sorry guys, I am really a nice guy, but Cummings? Does the badge on your fender say Cummings? Mine says Cummins. The letter 'G' is not even close enough to either the 'N' or the 'S' to call it a fat finger on the keyboard. I see posts all over this board where guys say they have a...

i love the gears i wouldnt mind if they were a little lower . i can see no reason for these trucks to be geared lower than 3. 73 i get hand calculated 11mpg even haulin the big loads :D You are running 3. 54 gears and state that you wouldn't mind if they were a little lower. Then you...

The noise, and not to mention the strain the stock fan puts on the engine. I was doing MPG tests at different speeds last summer. I was getting 24 MPG at 60 MPH, but when I slowed below that, the clutch engaged all the time and I got 18 MPG at 55MPH. I cant believe an electric fan is not out...

My supplier in Tulsa is telling me the same thing about availability as Morse has posted. AAM is saying mid-May for availability. I am wondering if they are just now beginning to make the 3. 42 gears for the current 11. 5 inch rear end we have. I am still excited!

Contacting AAM Guys, Due to the interest, I emailed AAM back to ensure they were OK with my posting their contact information. Here is their reply: Dave, Please have them contact me Bill Laughman American Axle & Manufacturing Sales Account Manager -- email address removed --...

You guys make some good points. I only tow 5000 lbs max. I have been in the Smokies, (I-40, eastern TN, western NC) 6% grade, pulled like a freight train, even when traffic and curves kept speed down and RPM's as low as 1500, never unlocked the torque converter. By the way, does anyone know...

Awesome Morse. I was just a little too scared to put mine in and head to CA and find out i had done the wrong thing. Keep us posted.

More thoughts on wind resistance... Guys, I just made my monthly 500 mile run. North/South highway, 250 miles one way. Overhead mileage is always 2-4 MPG low, but a good tool to check mileage differences. Driving south, sustained 20 MPH headwind, constant 65 MPH, overhead read solid 20...

A few interested folks have asked for info about 4x4 and gears for the front diff, here is the info from AAM: To convert Chrysler (Dodge Ram) to 3. 42 ratio: Rear 11. 5" Gear Set - 40045439 (New) - (Fits both GM and Chrysler 11. 5 Rears) Front - A Diff Case and Diff Kit change is...

I look at it this way, if I spend 600 bucks and do get 2 MPG increase, it pays for itself in 25,000 miles. I will put 10 times that number of miles on my truck, so I could net $6,000. 00 savings over the life of the truck. Show me another mod that pays like this, I am not seeing them on this...

Merrick, Thanks for the above info. I was looking through posts to figure out how to correct the speedo. I have a few gauges ordered and will get them on before embarking on a 2500 mile towing trip in late April. Will get baseline numbers from that trip, then install the gears and...
