Anybody re-gearing their diesel?

[Buttercup 3.0]

That mopar-parts picture looks like the filter includes the housing which should be reusable, no? If so, the actual filter component may otherwise be identical to the gen2 filters which can be found for cheap just about anywhere.

It does come with housing it is reusable but the filter is not the same as the gen 2 I checked the only way currently to get it is with the housing but as time goes I’m certain it will change and we will be able to just get the filter.

@Buttercup 3.0 (Shawn) I believe is going to 4.56's this week!

I’d go 4.10

Should be able to pick up 4.10's from the gas burner guys for a song but man that's a lot of work for such a small bump.

 

[Buttercup 3.0]

I’d go 4.10

We went 4.56 with the 39s we run it’s perfectly matched to the factory specs

Im running 37's with the stock 3.73's right now but just purchased used 4.10's to throw in the pumpkins... using the new tire/old tire/stock ration formula it comes out 4.18 for a new ratio... the 3.0 doesn't notice the 37's are under it but i wanted 4.10's to up the rpm's a few hundo to get it closer to stock...

Only a couple hundred invested in gears and small parts...

I went to 315’s because I think they look better and to get the belly up. Gears are 3.73 still. Wanted to report mpg have dropped by 2, last tank average down from 26 to 24. KO2’s on stock wheels, 35 psi

Any update on how the 4.10s are with the 37s?

Never installed them... going 4.56 next month

What kind of MPG are you getting highway?

I went with 4.88 and 40’s on mine. Being built as I type this... hopefully it’s done soon the anticipation is killing me

 

[Jteakus]

I'm eager to hear how the 4.88's and 40's play together!

 

[guarnibl]

Interested to see how this turns out. Ordering axles I think this week and trying to determine gears.

60s?

60s?

yup

Yeah. Rather sell the stockers now when I can still get money for them. W/ Tazer adapter, you can actually use your factory locker switches now even with the Currie axles (assuming you go e-locker of course).

Only issue I'm running into is Currie's site doesn't list anything below 4.88 and I don't want a 9" -- so will call and see if they offer 4.30 or 4.56. I'm pretty sure 4.56 will be ok for 37" daily use but gotta run the math (concerned about 8th gear RPM @ 70 mph).

Daily use = 37" KO2's on AEV Ram HD Katla wheels (ride quality, noise, snow performance)
Dedicated wheeling trips = 42" MTs (looking at treps, new trail grappler, or crawlers) on 20" forged beadlocks (not sure which wheel I'll go with yet, but has to be forged).

Will likely run a fender chop kit as I don't think 3 1/2" of lift will clear 42's otherwise. Buddy of mine put 39's with that and there's room for days with the same lift. I'm running Fox's new 3.0's internal bypass shocks w/ adjusters front and rear with air bumps, the shocks are for 3-5" of lift, so even if I have to increase a bit should be good.

edit: Currie confirms I can do 4.30 and 4.56's. So now have to decide.

Mine is in the shop now going to 4.56 on 37's. I use it to tow a camper and even though it pulls it with no problem, I'm hoping to spend more time in the higher gears and get the temp to stay in the normal range better when climbing mountains. I took it all over Moab and Ouray with 3.73/37's combo and had no issues with performance; if I wasn't towing I wouldn't have done it.
