BDS 6" with Bilsteins at 2.8" and 37's

JB1 · Aug 10, 2017

Thanks, If you could please get me a measurement from ground to top of step when down that would be very helpful. Just a side pic while standing up, maybe back view looking down the side showing how much tire sticks out would be great, tire clearance pics (thinking of setting my bils at 2.1)cant get enough of that truck :favorites13:

I assume you have a 5.7 Hemi. What kind of MPG's do you get with a 37 tire? I wanted to go to 37's down the line with my 4.7. Though I'm thinking I'll have to regear also.

Hemi450hp · Aug 13, 2017

Mileage suffered quite a bit because it wont hold 8th gear on the highway anymore. I'm down to about 12mpg now. Was at 15mpg on the 35's.

I'm averaging 15mpg w/ my 37's. Mostly highway @ 80 mph

Which tire? These Toyo MT's are taller, wider, and heavier than just about every other 37" tire on the market. I'm nowhere close to that at 80mph. My truck wont hold 8th gear at that speed with the 8sp and 3.92 gears, so I end up running in 7th gear at 2500-2600rpm the whole time. I drove 4 hours this weekend between 65-75mph, and the best I saw during that stretch was a 12.8 average. I've always been a fan of more gear, and with 37's, it seems like a must have to maintain performance and mileage.

I've got the Toyo RT's 37x13.5x20

If you're going with a 6" lift and 35" like I have you'll still have a hard time holding 8th gear due to the drag.

It will hold on flat piece of road below 70 mph (3.92 gears). I'm in Colorado so power already sucks up here, I usually lock it in 7th gear. Going to get a tuner here in a couple months see if that helps.

Hemi450hp · Aug 14, 2017

Mine has the 8sp with 3.92's, and it held 8th gear fine on the 35's. It didnt start staying in 7th until I stepped up to the 37s

Would the 4.56 gears be to much for the 8spd to swap to considering your setup

With 37's, I dont see any problem at all with running a 4.56 gear with the 8sp transmission. Its only the drag racers with shorter 28" radials/slicks that would have trouble trying to run that much gear with how close 1st-3rd gear are on the 8sp transmission.

I know what I'm ordering when my 35's wear out if you have the stock LSD do you plan to upgrade it?

Did a little experiment on the way home from work. Reset the mpg indicator and averaged 16.2 @ 80ish. 17.5 final adding 60mph rural highway plus two stop lights. As the pics show, I was able to get in 8th. I figured out that I had to feather the throttle to get it into eighth. Driving in STL w/ mild elevation variances. I could get it to stay in 8th down hill, flat, and most of the uphill portions, but would have to feather again on down hill to kick back into 8th. Also have pedal commander or sport 3 mode.

1) the truck is completely BA, well done! I'm liking the 18x9s, vs 24x14s and all that instagram nonsense. The blue and 6.5ft bed is legit. This is the exact truck I want, but I want memory seats (WHY RAM!?).

2) I'm glad you are being honest about the gearing, its nice to hear it directly from the horses mouth so to speak. Everyone acts like they don't need to regear anything these days, on any make and model, which is just a lie. Its such a critical part of enjoying a lifted truck.

3) you are right about the tire, you picked one of the WORST ones on the market for mpg haha. Heaavvvvyyyyyy. But at least you got arguably the best tire ever made and not some cheap blowout waiting to happen. That's worth the mpg penalty any day.

WhiteExpress · Aug 16, 2017

Damn sir! That's one beautiful truck. Love that you didn't go with the bro'd out 'stance'.

45.75" on the Driver side and 46.25" on the Passenger side

I find it amusing I have the same height leveled on 37's. The difference between 1/2 tons and 3/4 tons.

This is right around where I'm at with my 6 speed.

Insane. You're running 37's with a leveled 2500?
