Oh... yep a full-time Selectrac t-case would be a nice option for JK Wranglers too. We're plumb tuckered out telling folks not to drive their part-time t-cases in 4x4 on the streets!

And, of course, thanks very much for your response to my earlier question.

A V 8 !! THAT"S Crazy Talk !!!

LOL



Never heard that before .....

Well, we're not "warranty policy" experts here, but just remember that if the servicing dealer determines that the failure was a result of the modification, then it will not be covered. Installing larger tires (which I'm going to presume is why you lifted it) increases the forces that the axleshafts, etc. have to deal with.

Also, make sure that you have the regular inspections performed that are required to maintain the powertrain warranty coverage.

Since the Wrangler is probably the world's most modified vehicle perhaps you might be able to answer the question about modifications affecting a Jeep's warranty.

Some on this site say that unless the mod directly affected the part that fails, there is no warranty problems. Is this true?

I realize you guys are engineers but maybe you can clear this up? It seems some dealers don't know this for sure.

And thanks for being here!

Wow, nice to see you guys actually getting involved with the community.

Heres my question. Why scrap the tried and true 4.0 for the V6 in the JKs? I have heard it was because of fuel economy, but I don't know for sure.

As cheesy at it might sound, thanks for making the Wrangler a vehicle that is so easy to customize and make our very own.

My last question is, where can we get some of the interior parts (steering wheel upper, and tranny shift lever and surround) and that were shown on the Wrangler Ultimate?



Or were these just one off's and never intended for production?

The items shown are just one off's to gauge customer reaction. And many have said they like the trim upgrades. We currently sell 4 different instrument panels overlays - but not what is shown. Your dealer has photos of the ones that are available. Thanks

A HEMI in the Unlimited. C'mon, it's got 4 doors, 35" tires, 4"+ lift, people and cargo to haul!



However, in my opinion, the 3.8 is top notch for the 2 dr JK.

[Jerry Bransford]

Oh... Jim... would you please kindly confirm once and for all that you confirmed in our years-ago phone conversation that the TJ's air intake system was designed specifically to be very free flowing and that we're just wasting our hard-earned $$$ buying aftermarket air intake kits? Thank you man!

On 2008 JKs and the TPMS system. When upgrading to larger tires, a lower air pressure is sometimes required for proper tire wear and handling. There doesn't seem to be a way to recalibrate the TPMS for the new aftermarket tires. Has this been addressed?

I should have mentioned that I know the dealer can (for $55), but I'd prefer the Yellow Box approach (for a few $ more) for fine tuning and future flexibility to change again, if it doesn't cause problems. Would it cause problems to install it as described in prior post? Thanks.

See post #77 - basically addresses the same question about modifications vs. warranty coverage

How much boost are you running?

[Photojeep]

Ok, nevermind. The post directly above my question answered it.

Thanks,

good question....the tipm controls the dome lights in the sport sound bar ...you would have to turn the dome light on to use the push to switch option...

It does flow OK.. but the bigger issue is filtering efficiency.. aftermarket filters just do not hold up to the paper elements. You are letting in more dirt into the engine.

So, actually, an aftermarket might flow a "bit" more.. but not worth the trade off.

And yeah, we ran actual dyno tests to test this stuff.

Good Day
