Tank is plumbed in through the the fill line. We used a summit racing T with a check valve. Had to reduce the size or the T to fit the fill hose on the jeep. The check valve allows me to leave the fuel draining all the time into the main tank. Works great.

Just made a trip to New Mexico and back with a little improvement but not near enough for me. The Taza’s ability to turn on the fan for sure helps. I’ve also modified the Rubicon hood vents to let the heat out. I do think this helps a little. You can feel the heat coming out the engine bay...

G This for sure looks like the most viable option. I'm excited to see how this goes for you. I did add an additional high speed fan and opened up the fake rubicon vents on the hood. I tested last week and it was better. I was able to maintain 230-232 coolant temps and 245-250 oil temps...

I started the fan at 230 oil temp. Didn’t really help on mine. I’d say it prolongs it by a few miles.

Did I miss what insane diesel is doing? Did I miss the post on insane diesel??? What are they doing? Here’s mine on a test run pulling travel trailer. Have tazer and the fan was on. Didn’t help much if any. I have a local shop working on some type of fix.

285/75r/18 Ridge Grapplers which are 35.07x11.2. Clayton said I can run 37’s

Nothing major. Mud and over a few logs showing land. Not made it west yet! Did crawl up a tree on the beach.

So I have had this lift on my truck for going on 6 months. All I can say is WOW! I am completely happy with everything about the lift. Ride is better than stock and it drives amazing. I went with the Fox shocks as that is what Clayton recommended. The guy who installed the lift for me said...

Not saying you don't know how to do the math. I feel like the truck could use more power especially when pulling. I am not a fan of programers, and IMO regearing seems to be a logical solution. But I do get what you are saying. So how do you fix it falling on its face in the mud? I use...

4.88’s and 35’s is a 15% change to the RPM at 70mph. I’ll go from 1750 to just over 2000. And in the mud which I’m in from time to time it will help the motor not fall flat on its face when shifting gears.

I agree the truck is perfect until you give it a decent load. I will post a performance update once I get my gears in. Going with 4.88’s and currently running 35’s.

Did you regear and run the same test again? If not then your reply means nothing. 4.88’s are over 30% more rpm’s with 33” tires than stock 3.73’s. IMO were the heat issue factors in the most on climbs. If the truck will climb a hill in a higher gear and not have to down shift as far it will...

Has anyone re-geared the diesel and still had the derating issue? Maybe I am wrong, but if the truck was lower geared it seems the engine wouldn’t struggle as much and hopefully not overheat as easy. I have towed with mine several times and seen the loss of power. Not had it go to limp mode...

Mine still showed it being locked. But you can obviously fill it being locked as well.

Just installed the Z adapter and it turned off the locker lights. Tested the lockers and the work. Guess I’ll go ahead and do my gear swap. Thanks to everyone for the replies.

thank you. It’s also telling me to service rear locker. Is that something different?

Still no axle in site from Jeep. So if I do the gear change will it fix my problem? I bought the tazer harness that bypasses the light but I’d like to know what the actual problem is. Does anyone know?

How many miles on them?

No metal shavings or chunks. Thanks for the reply. So now my big question is, is it safe to go ahead and do the gear change or should I wait on the dealer to switch out the axle?

I mean the metal in the gear oil.
