4.30’s in the truck!!

Recommended Posts

I have to thank Ben for letting me kill his weekend and do gears in my pickup. Words don’t describe how thankful I am for the help and learning experience. Yes I have new tools I need. Lathe, mill, router, pinion depth tools....  it’s all his fault!!!

 

Now the truck. Dead on 1750 at 70 mph. I am filling up shortly and will update as to what it did for my mileage. Drivability is way better. Trans shifts crisp and neat. Everything I was hoping it would do. 

 

Thank you again Ben. I will be sending you a care package.

Mileage results are in. Best mileage I’ve ever gotten out of this truck was 18.3, stock everything. Average before tires was 15.3-16.8

I netted 17.7mpg traveling 72-75 the whole way. I’ll take it!

Are you using the Procal for the corrections?

 

Anxiously awaiting the new version for the ‘19 DT and JL models as well as the HD’s.

I am using the procal. It was my tire size changer before I tuned it. 

 

When i adjusted gearing, it didn’t honk and confirm changes. I am not sure if the change stuck or not. But, my lie-o-meter is closer than it ever has been. 17.7 hand calculation and 18.2 indicated. 

 

Pretty sure I’m going to leave well enough alone.

Just curious why 4.30's? I know why others have chose them I was just curious why you went with those vs 4.10's, 4.44's or 4.56's. I almost wished I went with 4.56's, but for completely different reasons than you, better power to the ground in the dirt. I have been averaging around 15.5-16 with my 4.10's, well when I can keep my foot out of it LOL. Ben you're a good man...

I wanted 1700-1800 rpm when cruising down the road. IMHO it’s a good balance between mileage and killing my trans/truck when I tow and work the pickup.

My truck with stock tires runs about 1725 rpm's at 70 mph on flat ground and that's where it spends most of its time commuting. I am averaging 17.8 mpg hand calculated and 17.6 on the lie O meter. 

Sounds like you are about spot on compared to a factory setup.

That was the plan. Plus a touch for the rotating mass. 

 

Ben said it felt like a stock pickup. Biggest compliment of the day!

The only thing I would change is the name on the title...😀

I’m down for that!  The bank and your name would look great on the title. They’d ask you for the payment, I’d keep driving it. Win/Win

Mark - 

 

What size tires are you running? Any engine mods?

 

Thanks - Have been thinking about a gear change and some other changes...

The truck is setting on 37's.

 

I tow on stock.  I DO have the truck tuned though.

 

I recently went to Indianapolis with this setup, pulling a 35' gooseneck with another CC/LB 2018 Ram and some miscellaneous stuff on it otherwise.  Crossed scales at 23,900.  Net MPG going over an back was 9.4mpg.  Highest was 10.2 lowest was 8.3.  All speeds were kept at 72-75mph.

 

My empty mileage came up significantly.  I am now back to 17-18mpg just like it was stock.

 

I would make the swap in a second if I needed to do it all over again.
