2020 1500 w/ latest Mopar Lift And Tires

[Jackthedrinker79]

Truck is a 2020 1500 with latest version of Mopar lift and Atturo Trail Blade XT 275/65R20.
Truck rides awesome, took the alignment technician two attempts to get it right.
Tires were Road Force balanced and took very little weight.
ECU calibration is required, truck will hunt between 7th & 8th without it.

I have the exact same tire size I’m about to put on mine so it’s cool to get an idea of what it’ll look like. Looks great. Not too stuffed and not too much space. Never knew about the ECU thing. Did the dealer calibrate it? Does that also account for mileage and speedometer issue with bigger tires?

What are your ground to fender measurements? I just had the updated kit installed as well and also going with a 275/65/20 tire. Just trying to figure out if its worth it or if I should just go with a 285/65/20 tire instead.

What is your gear ratios? If 3.21, how do you calibrate the ECU for the shift changes?

How’s the noise on those??

If you're asking me, I have 3.92 (with the ORG). I used the Rough Country speedo calibrator, which isn't very accurate... I had to select the 33.25" setting for the speedometer in my truck to be accurate.

If you're asking me, the noise is surprisingly minimal compared to the halfway worn OEM Falkens. I would absolutely recommend them based on lack of noise. Haven't had a chance to test them in any mud (it's been a drought here in AR).
