Just watched a few youtube videos about the Gladiator, they were saying that because of the tow rating on the Gladiator, the factory had to make the holes in the grill insert larger to get more airflow to the engine. I for one am very disappointed with the high "normal" engine temp of my JLU Rubicon with 3.6, was wondering if the Gladiator insert would fit the Wrangler grill and if anyone thinks it would make any difference in trying to keep temp lower. Its not even summer yet and im already getting temps of 222°-232° during normal city driving. Most of the time i see about 198°-212° but it does reach the higher temps during stop and go/heavy traffic driving.

Strange, I'm in MD and on hot days I seldom peak past 195.....

I doubt larger grille openings would make much of a difference in stop and go driving. The fan can only do so much under such circumstances. Plus you’re sucking in the higher temp air from vehicles around you. That’s why many manufacturers consider stop and go driving as severe duty insofar as maintenance is concerned.

Those temps don’t seem excessive for the conditions.

It's not just the holes on the grill slot inserts that are larger. The Gladiator grill slots themselves are wider than those on the JLs to allow more airflow. You could not put JT inserts on the JL, but since the grills are the same size, changing grills would be an option.

Yup. I would be curious if the larger brakes and stronger wheels would bolt up too.

I’m sure most of the parts will bolt up. It’s like a rubicon parts bolt into a lower model level as well.

Interesting. is there that much better stopping power? With 35s the stock brakes are still sweet but if I go larger it might be something to look at.
Well, it needs to stop 6000 lbs AND a large truck, so the brakes are substantially larger and more powerful.
