So the 3.21 really is The BEST gear for towing. Great! Now that's settled. End of thread... I'll see y'all later, be careful on the way home...

I started to leave some good data here but realized that you and others had already provided the same info back in 2021 (y)

Were you then grabbing for a column shifter that wasn't there? Been there, done that...

Anyone that thinks that 3.21 gears are "bogging down" the Hemi at any point, needs to research exactly what volumetric efficiency and peak torque are. And why they both occur at the same RPM.

Simple arithmetic: >Large displacement engine + >more RPMs per mile = more fuel burned.

Interesting... thank you. By "6th, 7th, and 8th gear at a fixed speed on the same stretch of level road falls out to be about 20, 19, and 18 MPG respectively." What speed were you maintaining? Was it the same speed in all gear ratios? Are you basing this on the mileage/vacuum gauge in the...

Interesting to hear from an actual e-torque product specialist:

You should've hung out for the SST, Man.

In summery, just fill it up & drive ur truck.

Back on the gear ratio topic: If you changed to taller tires but did NOT correct the calibration of your speedometer, then consider this: If larger tires slowed down your speedometer then it also slowed down your odometer by the same percentage. If 70 MPH on the speedo is really 75 MPH on the...

If you changed to taller tires but did NOT correct the calibration of your speedometer, then consider this: If larger tires slowed down your speedometer then it also slowed down you odometer by the same percentage. If 70 MPH on the speedo is really 75 MPH on the road then you have gone more...

Did somebody say tires? Lol! https://5thgenrams.com/community/threads/falken-rubitrek-ftw.39291/

Lately I have been eyeing the Michelin Defender LTX M/S2 as it may offer class leading road comfort and quietness. But in the appearance department... the Rubitrek is a much better looking tire on the truck! Falken Rubitrek weigh 46 Lbs & cost $237 / tire. Defender LTX M/S2 weigh 39 Lbs & cost...

Not at all. The move to a one inch taller tire will slightly "slow down" the speedometer and the odometer by a small percentage. So if you do not recalibrate it my appear that you lose 0.75 MPG. But that's because you are actually traveling more miles than what the truck is registering.

Do taller tires "slow down" the odometer just as much as the speedometer? If so then that alone reduces your calculated MPG by the same percentage. Be it calculated on the dash or by hand.

well, I found them for $325 (plus shipping - Cbty2050 😁) Read this post and see my invoices, to see how I saved $2400 by doing it myself instead of dropping it off at the the dealership. https://5thgenrams.com/community/threads/cracked-exhaust-manifold.54873/#post-820023

Most assuredly it is, but here is the rub: Bilstein B6 4600 shock for coil spring, Part Number 24-329132 = Widely available from several retailers for $113 each. Bilstein B6 4600 shock for air bag, Part Number 68323489AD = Only available from the dealerships for $360 - $500 EACH! And I...

I wish that I had taken more pictures of that, as I too am still curious about that as well. On the passenger's side that I did first, I undid the factory SS clamp on the accordion boot, only to realize that it wasn't really necessary. The accordion boot appears to just be a dust cover. It...

I'm in ❤️

The rear shock physically measures and mounts up the same on both coil or air sprung applications. But in the front the snap ring for the coil spring perch sets much higher on the shock body than the snap ring on the air sprung shock (from what I have seen in pictures) Here is a picture of my...
