I would think a junkyard 3.6 & tranny combo would be pretty cheap since they're used in so many FCA vehicles. Don;t get me wrong, I love all of the attributes a V8 brings to the table but are they REALLY necessary? I can def see a V8 swap
if you're running 40's and/or you live out west & travel through the mountains. My Jeep was sucking wind going through Colorado this Summer. But where I live, honestly the 285 hp the 3.6 has is plenty.

Yea, around town in LA my 3.6 keeps up just fine with traffic. Loaded down with camping gear this summer though was a struggle getting over the mountains to Moab. I'm fine with the power I have when empty so I have no need yet for more. Yet......

Hahaha - that 'YET' bites us in the ass every time, doesn't it?

I have wondered about this scenario too. Is it even possible? Not that I'm looking to do this, but why hasn't it been done before?

I've heard it's not possible. But if someone can put in a V8 why not the 3.6l?

Edit: An excellent comparison would be between the capabilities of Moby's LS & Rubicat' 3.6. They both have the pretty much the same setup now except for the motor, right?

For sure. I'm not going to run 40's, but I want the Jeep to move forward when I press on the accelerator. I've been able to go everywhere others said I won't make it without 4" lift and 37's with at least one locker. So proved them wrong! [emoji23]

Dynatrac does have new pricing from SEMA that you may want to look into. Also, they can build the axle however you want with different locker options. They even do have options for RCVs. May be worth a call. A few members here have had issues with RCV not standing behind their products, just an FYI.

Good to know. I hate when companies put profits over quality. Not saying that's what they are doing. BUT... [emoji848]

Idk. I'd just regear. You can buy a lot of gas for what a stroker and supercharger will cost.

Hmm interesting chart. I found the one for the 3.6 as well and i find it not very accurate. My jkr which is a 3.6l 2016 model and according to the chart i would be running a 4.56 gear ratio not a 4.10. Am i missing something here?

Tire sizes are actual tire measurements. I'm running 35's, but the actual measurement is about 33.5". I have an automatic transmission, and programmed for tire size with a Procal, and my RPM nearly match the chart.

Are you saying that your RPMs match the 4.56 on the chart or that 4.56 is in the performance zone?

GraniteCrystal · Nov 30, 2016

According to this I could comfortably run up to 43" actual size tires on 5.13 gears. Hmmm. Based on what I've read that seems a little ambitious. I think most guys running 40s are on 5.38s much less anyone running like a 45

Yes. My rpms are matching the 4.56 ratio on this chart with stock rubi bfg mts on it. That's what has me confused.

So it doesn't go by the manufacturer's size then, but the actual size?

Are you sure you're using the correct size? Try measuring your tires using the method in this thread. What transmission do you have?

I can't speak for anyone else but I've always used what's written on the side wall when looking for the right ratio as listed on the charts above. I run 40" tires and with 5.38 gears.

Draconianwinter · Nov 30, 2016

Well the actual size is around 30.5 if i remember correctly not the 32 they claim so i see it is the actual size of the tire being used not the size the manufacturer claims it to be. That's what had me scratching my head since every damn thing else goes off the sizes stated by manufacturer

That's what i thought we were supposed to go by as well until i found that chart. Which was why i was really confused

Thanks for clearing that up. After i found the tire size i entered in my phone which again was 30.5 it matches up.
