I have no personal gear experience with Jeff but from talking to him about brake kits and the installation thereof, he is sharp and attentive.
Is my LJ Rubicon supposed to feel gutless?

I still don’t think that motor is all it’s cracked up to be. My family has a 2013 JKU that we bought new. Now has 150,000 miles. Probably 85% highway. It’s burning oil at an alarming rate. We’re just driving it until it dies considering the miles are pretty much depreciation free at this point.
On the other hand, my TJ, which has been driven by the exact same people as the JK since we bought it new in 2001, has 226,000 and absolutely no engine issues.
Anecdotal evidence I guess, but the 3.6 hasn’t treated us all that well.
So, your statistical sample of one dictates how all of them are? Perfect.
That’s why I edited in the anecdotal evidence part at the bottom, but you beat me to the quote. I don’t think it is a groundbreaking opinion that the 4.0 is more reliable than the 3.6. Burning oil isn’t unusual for 3.6’s from my research.
Pretty much, especially since there are no low mileage 4.0 that have ever thrown a rod, burned oil, blown up or heaven forbid, had a leaking rear main seal.
But I thought the leaking main seal was a factory option so you wouldn't need to lift the hood and use the dipstick to see if you still have oil.
If absolute reliability is your metric, then we should all be running the 60 hp Go Devil motor out of the old Willy's manufactured with today's technology. Myself, I'll temper a basic level of reliability with a lot higher performance with much less weight and call that outstanding.
No, about 2800 @75mph. The Jeep is still gutless. Going up a slight incline it quickly loses speed/power. My expectations are too high for this platform, I get it. But I’m not just complaining im doing something about it.
I only responded to voice a different experience. I just expected more by the way people tout the upgrade. Yes it made a small difference, small.
I don’t value absolute reliability over all else. But I do want more reliability than I’ve found and many others have found with the 3.6L. With a perfect maintenance history and all highway miles (yes, they’re all on interstates pretty much), I would’ve liked my 3.6L to have lasted longer.
The 4.0 certainly isn’t perfect, but I think it’s great for what I use it for and the reliability is a bonus. I’m sure the 4.0 sucks for the racing scenarios you brought up when we had this discussion over a year ago.
It really sounds like you have something else going on. I'm one who re-geared when I went from stock size tires to JK 32" take-offs or from 3.73 to 4.88 and it was more than a small difference. When you go up the inclines are you kicking it out of OD?
We all think about things differently. I just happen to be one who accepts the 4.0 for the POS it is and don't happen to place it on any pedestal of admiration. They are the AW-4 of the motor world. They are fairly tough, that's it.
I do not, should I? I let it kick down on its own. I think the biggest problem is the elevation as I stated above. I just had it dyno, 107HP @the wheels.
Generally, the 4.0 will not pull much of an incline with any gearing and 35's and the auto in OD. At elevation, it is just worse and you may try kicking it out of OD with the button and see if that improves your driving experience. If not, you may be looking for some assistance in the form of abnormal aspiration.
I paid ~$2K to regear my '05 LJR about 2 years ago. It was done by a very reputable guy who does multiple regears per week. Personally, I would focus on the reputation of the shop doing the work with price being a secondary consideration.

I'm not sure this is the correct part or not, and I assume it is in stock.
