3.31 Ratio : 2021 5.0L

[Nomis]

Going from the factory Hanook 275 to General 305, basically both are 33" tall, but 10" vs 12" and 40ish vs 60ish lbs. respectively. So wider and heavier than the factory tire. Getting that heavier tire to rotate (acceleration) is where I noticed a change. Not terrible, I almost don't notice it, nevertheless it's an increase of ~20 lbs. of rotational mass now. I do feel that I'm driving more aggressively (find myself 5-10 MPH over the limit lately) but I don't know if it's because I feel invincible, over compensating for the heavier tires, or hyper aware of the changes I made. I think once I start driving normal again, I won't notice anything. I did get to the lake on New Years and I didn't notice any change in light to light traffic or going up a known step grade in Austin between 360 and 620 on 2222; she just stayed in 7th gear and pulled like a champ.

I'm asking about the pedal commander because even before the wider/heavier tires, I felt I needed a little more zip in my take offs.

I did look into re-gearing, but man-o-man, the thought of tearing into a new truck made me tear up a little. And then after reading a rear diff gearing comparison article in Trailer Boat I felt better about the 3.31 and the 5.0.

I'll let you know how it is once I install it and try it out a bit! Seemed guys on here liked it a fair bit so I figured I'd give it a whirl

That's OK, I didn't notice it either 















How do you like the Pedal Commander @Nomis ?

Hey bud I installed the pedal commander and I'd say it's worth it. Drove it to town and back to play with it a bit and Sport + is almost too much.

I have the eibach and tires and everything installed and the PC completely changes how the truck reacts to throttle.

Thanks for the update @Nomis ! That's good to hear. I was sorta waiting to hear from on your test It's not bad the way it is and Sport mode is too much and I have to remember to select it.

What mode did you end up using?

When both truck and pedal commander are in sport mode/sport mode + you will be giggling an evil villIan laugh

Pedal Commander changes the feel of the truck!

I was skeptical at first but now a believer in the product.

I'm getting 19.5L/100km but I live in a small city that is nothing but short trips. Lots of idling as well. Just installed 285/60/20 KO2s so I'm sure the gas mileage will get slightly worse.

You used to be able to get the 3.55's in the 5.0, my 2015 had the 3.31 gear, but I remember the 3.55 was available, my brother and dad's 2018's both have the 3.55. I was kind of surprised that when I ordered my 2023 this week that the 3.55 was no longer an option. I went with the 3.31 this time around too, because most of my driving is highway and I wanted the fuel economy.
