392 Gladiator V8 Hemi confirmed by Jeep CEO!

[Mad Jasper]

Your right 5000 lbs.

Mad jaspers point was, jeep is doing a poor job with a motor thats been around over a decade, the pentastar, with quality control and stocking replacement parts for often low mileage motors. They are not building our confidence with regard to investing in a newer more complex powerplant like the hurricane.

I know someone that recently filed for chapter 7 bankruptcy because they bought a used Silverado, 2 or 3 years old. One of the lifters went bad and it was just out of warranty at 74000 miles. He was still paying on the truck and could not afford to fix it so now we pay for it. He replaced it with a used Chrysler 300, just over 100k miles. It developed the tick and is in the shop. He only put about 5k miles on it.

These motors are trying to do too much, made by incompetent people, hired by greedy people and regulated by people that most likely have never done any real honest work in their entire lives. Putting a 4 cylinder in a 5000 pound truck is asinine. Jeep, Toyota, gm, can keep their thumb hole stock truck engines.

Nailed it.

The business case was not there for them to try and re-engineer the cooling system to meet the higher tow rating targets they wanted and offer a Gladiator with the 2.0 higher priced option.

They had real trouble getting the cooling needed for the 3.6 back then, too. Then add the heat of a turbo to the mix......
You probably saw the story on the heat issues in those days.

I followed the towing testing: It had to pass a engine cooling test, hauling I believe 7500 lbs., with a certain ambient outside temperature, on a given uphill grade for a certain duration. It was a real challenge for them, because they were limited on the square inch of frontal area of the Radiator. So the final resolve after months of testing was, the new grill design, to allow more CFM air flow. A 850 watt engine cooling fan motor, along with a redesigned cooling fan with more blades and a different blade pitch. A higher out-put alternator was also needed, to supply the new 850 watt fan motor. The original towing approval, was only for the Gladiator Sport.
This is the way that I remember it, but I am old, and my memory is not what it use to be..LOL

This will be cool, but the last thing I need is a $100K mid size truck.

That can't be true.

Every Jiffy Lube mechanic knows engineers operate 100% freely with the ability to do absolutely anything they choose with no consideration to cost, packaging, availability or sourcing.

The only reason engineers ever get anything wrong ever, is because they're inherently stupid, and if the lube tech who got fired from the Jiffy Lube had been there, it would have a Hemi that ran at -40C while towing the USS Nimitz up the Rockies, it would never need servicing, but if it did it would pop out like legos because their intelligence doesn't surpass a See n Say.

You guys all have it wrong.

They should just sell Gladiators with Gen III LS engines

I told my ole lady if the Gladiator lays down I'm gonna cruise every online market place and find a 2009-2013 Silverado/Sierra (the days of the Gen 4 LS and 6 speed auto) with the lowest mileage I can and drive that.

Some days I long for my '05 Silverado I had. To me, those were one of the peaks where a truck was comfortable, useable, drove nice, and was super easy to work on.

It's not that those don't have faults, its that I already own a Gen 3 5.3L/4L60E and a Gen 4 6.2L/6L80E and so I have no doubt in my mind that I could keep one on the road, indefinitely, with readily available parts from nearly every parts and performance warehouse in existence, and do the work myself - compared to all this new twin turbo, insanely complex, lift the body off to fix anything garbage we have now.

Don't worry. I'm trolling.

Only about the LS Gladiator part...

Sort of...

I have a 2.0 in my 2024 JLUR and it runs very well. A 340HP SRT tuned version of the 2.0L would work really well in a JT. If possible use the 3.0L like it my 2025 Rebel that would be excellent. People go on about the virtues of the 5.7 Hemi. The 3.0L S/O is much better it just doesn't sound like a V8. The majority of the issues in the 2025 RAM were related to the new Atlantis High electrical architecture not the 3.0L engine.

This is pretty similar to the way I view the 5.7 as well. Every one I have had has either been solid, or easily rebuilt over a few whiskeys with any of the ample parts (performance or stock) available these days.

For this matter - it's one of the reasons I kinda like the 3.6L.

Yea, its kind of a dog, but its only major / common fault in the PUG is the cams. Turns out - the cam and followers are actually pretty easy to do (well, for mechanically inclined folks)...you can even do it without pulling all the front drive off or the timing covers.

It's simple, the bottom end is solid in stock form, and the top end has a 'manageable' defect that shows up in some vehicles.

Sure is better than the nightmare that A twin turbo with packaged intercoolers Hurricane 3.0 would be, especially with the all plastic ball valve thermostat that is already a failure point AND hard to replace.

For sure. I just want more grunt while rowing gears than the 3.6 is ever gonna be able to provide. While I am old and am completely fine with putting around these mountain roads at 35mph....I bought the manual this go round because I sure as shit want to get to that 35mph as quickly as possible.

Or......and hear me out......I could gut the entire drivetrain and drop the ol' Buick Dauntless V8/4 speed combo that I've been storing behind the shop in a beater J2000 in there......which somehow is probably still more likely than Jeep ever actually giving me a 5.7 with the manual.

This one went for only $50k on BAT.

Same, I have 05 HOE 4wd with 4.8 and puck &key lift with 35s, only has 125k for mileage. I'll roll that if my JTRD kicks it. So easy to work on, like a Fox body Mustang.

Source: Jeep Gladiator 392 V8 Confirmed, Wrangler 392 Continuing Indefinitely

On Thursday, at a media briefing Jeep CEO Bob Broderdorf said the 392 cubic inch V8 engine will be leveraged in the Jeep lineup followed by, “Wrangler and Gladiator fans, and Hemi fans in general, don’t worry.”​

​

After this announcement, it’s unlikely any Jeep fans are resting, as some might be hyperventilating. Who’s ready for a four-door pickup with removable doors, roof, and a huge V8 engine? Prepare your bank accounts.​

​

Broderdorf said “after being out at the Rubicon Trail, it’s clear just how much people love the roar of the 392.” It’s worth noting, people traverse the Rubicon Trail at slow speeds, which means no engines are roaring.​

​

“The 6.4-liter Hemi V8 will have a home at Jeep,” Broderdorf said.​

I would have been happy with a 5.7 Hemi and a price tag a lot less than 100k
