02s are fairly cheap go with Mopar or NTK. Ive seen issues with some of the bosch ones on Jeeps. Jeep PCMs arent uncommon to go out but before changing it I would get the new quality 02s in and check your voltages, grounds, and heaters first.

The JK pentastar fan programming is backwards. Its a 10 Hertz, and the tables are opposite of what you think. For example, lets say your looking at the coolant tables and the lowest temp it shows is 196° the fan would be running at 90%, 200° fan would be 85% etc. The higher you put the number...

RCP ( Racing power company). Is the company and we use the 3x10. Get the biggest one you can fit. Since these are metal, not only do they absord the heat from the engine bay, they are also exposed to the atmosphere. Meaning you will need to check it often as the coolant will evaporate rather...

You can get a cheap one through amazon and they work the welds just dont look great. We get ours out of Cali, I just cant recall the name of the warehouse at the moment , they do cost more but we do not have issues with them and the welds are very clean.

How many miles do you have since you cleared codes or disconnecting the battery? The 02s usually need a few cold starts and need to be driven like 20 minuets each time, the cat wont set till the 02 sets. If there is a problem it will throw a code after the monitor completes

Theres nothing to get around, its perfectly legal to run other manufactures powertrains in different vehicles, you do need to run the full powertrain though, so engine and transmission must match. Running a hybrid, like a GM engine but Mopar transmission is not legal.

Yes, one our goals this year is to get the website going with more info, most guys get the info from our YT channel WranglerJKLS. Stop by anytime were there 8-5 🙂

All JKs have 241Js, so youre good 🙂

Glad shes working out Trevor, was actually gonna send you a text to check in. 😎

Teraflex ball joints typically need some miles to break in, The ram also needs to loosen up. But try 1/8 of toe in.

Is the radiator bled properly? Thermostat is good? Are there grill/radiator blockages? Is the fan running?

Just did mine 😎 thanks for video as always Eddie, and hope to see you guys down in Vegas soon!

Our JL has done this a few times, I thought it was maybe our side causing it but after doing diagnosis on it I didnt find anything relating to us causing it. That was about a year ago and it hasn't done it since, but 2 weeks ago I was driving to California and the steering wheel would freeze mid...

I actually gapped a 392 by car lengths with a JK 37s 4.88 LT1/10L80. They are really nice though. Congratulations Jay, I hope you never get rid of the JK!

Spectre 8136, yours is a K&N RF-1033. The K&Ns are washable but they are really expensive now 🤑. The Spectres say they are rewashable too but I havent tested that. We always just got new spectres when they got dirty.

We have Commie legal swaps 😉

Glad that LT1 is treating you good 😎 Hope we can meet up soon!

I think its safe to say we all missed the JT and happy to see it out again 😎

Luckily with the V8 I actually just removed that stupid paperweight. 🤪

Oof, thats crazy! Definetly good you caught now and not doing 60+ MPH offroad with the LT4..
