'15 JK: Trailer Tow Group v. 3.73 Gear Ratio

Hello,

I've seen many Jeeps with the "Trailer Tow Group" package which costs $295.

For example:

http://www.chrysler.com/hostd/window...BJWDG0FL508119

It includes:
  • 3.73 Front/Rear Axle Ratios
  • Class II Receiver Hitch
  • Trailer Tow with 4-Pin Connector Wiring
However, I've also seen many Jeeps with just "3.73 Front/Rear Axle Ratios" which cost $495.

For example:

http://www.chrysler.com/hostd/window...19851&type=new

It only includes front and rear 3.73 ring and pinion gears.

Why would the "Trailer Tow Group" which includes more cost less than just the "3.73 Front/Rear Axle Ratios"?

Are you sure you're looking at trailer tow, and not Max tow?

No doubt about it. It says so on the Window Sticker I linked to.

IMHO, its yet another start-of-model-year window sticker error.

I believe only the Max Trail Tow is suppose to include the 3.73 gears (and adds HD oil to them).

Interesting. If you bought this Jeep, noting that the window sticker said the Jeep included 3.73 gears with the "Trailer Tow Package," do you have any recourse if it was said to be a "window sticker error"? Or are you screwed?

In your example it indicates 295 for "tow package" with 3.73's like you said. Maybe that's what Chrysler is doing in 2015. The only way to actually know is if it's on the build sheet. I would think if it indicates 3.73 and it actually has 3.21's a reputable dealer would take care of it. Most, including myself, would believe what the window sticker indicates is accurate. Why would anyone initially not believe what's on the window sticker unless it was very obvious.

I believe 3.73's were part of the tow package in 2009....don't think so anymore. I think they separated them and you pay for both if you want both. The tow wgt limit is so low that Jeep likely considers 3.21's sufficient. I was not aware Max Tow on newer Jeeps included 3.73's.

I believe somewhere in the fine print is a disclaimer that they aren't responsible for typo errors. If you step back and think of it, if the regular Tow Pkg included the 3.73 gears, what purpose would the Max Tow Pkg have?

For your recourse, you didn't pay for the Max Tow Pkg, nor the separate 3.73 gear option, so you didn't pay for something you didn't get.

For 2015, we already know about the DM8 for $0 error, and the Hard Rock red stitching error.

Although you are correct in a sense, that is not how I would look at it. If he does have 3.21 gearing, he did not get a Jeep with 3.73 gears - if that is what he thought he was buying when he agreed to the sale, he has been wronged. There was no "meeting of minds", which is necessary for any legal contract. Not getting what the window sticker says is not right in my book - I don't care what the fine print says - I don't believe it would be legal to have fine print essentially say the description of the product can be wrong. I would not accept the Jeep if it did have 3.21 and the window sticker clearly says 3.73.

Hopefully, this is not an error, and Jeep has simply changed how they are offering the tow package in 2015. In 2014, you could either order the Jeep with the tow package and the 3.73 gears separately, or you could order the Max Tow and get both. Ordering Max Tow was cheaper.

I believe in the US you got screwed on the cost of 3.73 gears.
In Canada in 2014 the 3.73's were a $95 option.

I was on my phone, so I could not get to the window sticker until now.

Well, back in late 2011 (for the 2012 MY), Chrysler was putting in 3.73's for free for a short time.

I don't know if that is an error or a new plan by Chrysler, but the tow package plus 3.73's is nice deal.

I just checked one out in person. The axles to not indicate the gear ratio (to me). See pics:

That's interesting, but what does the lack of gear ratio on the axle itself mean? Are the axles normally engraved with the axle ratio if it is 3.73 or 4.10? Can you find any Jeeps on the lot that have "Max Tow Package" on the window sticker and see if the axle is engraved with 3.73?

Edit: When I plugged 52132650AC into Google, I get many listings for the 3.73 axle.

https://www.google.com/?gws_rd=ssl#q=52132650AC

I don't want to jump the gun, but this could really mean that Chrysler has thrown in actual 3.73 R&P gears in the "Trailer Tow Group" although the "Max Tow Package" is about $500 more and includes basically the same components (including 3.73 R&P gears). That is bewildering.

If its not listed on your window sticker, how can you tell what gears you have? Is it different stock depending on model, Sport, Sahara, Rubicon, Rubicon X? Unlimited or 2 door?

Find your build sheet.

Try this:

Build Sheet for YOUR Wrangler.

It's available through Owner's section on Jeep website. You have to register and so forth.

Thanks, It lists 7 pages if item, even the 5 gallons of gas that it has when it gets to the dealer. Very good information.

3.73

THis was posted in another forum. I can't tell if it was taken from the 2015 Wrangler brochure. If it was, this answers our question. Does anybody have a 2015 brochure to check?

Great find. I was on my phone and couldn't find anything while I was on the lot. That makes me a believer.

With respect to the 2 door Wranglers, I think that the evidence is clear (to me) that the Sahara $295 tow package gets you 3.73 gears. I am fairly certain that this does not apply to the base or Sport S. I have looked at too many window stickers to believe otherwise. I am not sure how long it will last, hopefully throughout the model year.


This will not apply to Rubicons.

I have no idea about the 4 door versions.

Why do you suppose it doesn't apply to the Sport S? Well, I think I will be checking out '15 4-doors tomorrow on the lot. So, I'll check out the part numbers on the axles while I'm there. I'll see if I have time to scope out the Sport S as well, and of course, I'll call Chrysler to see what's up. On the other hand, maybe it's better I don't call, 'cause if this is true, then I don't want Chrysler to find out (just in case they don't know)! lol

I'll be following this closely. Bought a bone stock 2013 JKU sport but sticker and build sheet both say I have 3:73s. Is there anyway to physically verify this? Are the axles stamped, marked, etc?

Edit: found out the axles should be tagged. I'll check tomorrow. Crazy thing is having to do this in the first place...too bad some window stickers have some mistakes.

Post up the part number on your axle(s). There's also the build sheet. I'm doing some research on Dana's website about the engravings on the axle. See what I can find out.

Okay, found something. Most Dana axles (if not all) have a number called a "BOM" or "Bill of Material" stamped on them.

azjb posted one picture, which I'm posting below:



It seems many BOMs have a number ending with a - and then followed by another number. Here we have 2018180-2.

Plug the number 2018180-2 into the following:

Dana Holding Corporation - The Expert Axle Bill of Material

Now, it only goes up to year 2013, but I doubt it's different for 2014-2015. Anyway, it says the axle is 3.73.

Axles aren't tagged anymore. They have a paper sticker on them with the axle build of material number on it. If you go to Dana's website, type in the BOM number, it gives all the info there. Here is a pic of mine. The sticker is on top of the axle, only visible through a mirror. The front is easier to see.

I just ordered a 2015 Sahara 2 door on Saturday. I was questioning the axle ratio since it seemed to add the 3.73 when the tow package was ordered (using edmonds.com to build). When the dealer built the Jeep with his system, the 3.73 didn't show and he said it would come with 3.21. I guess I'll see when the Jeep arrives.

I think the smart thing to do would be to place an offer for the jeep and clearly write in 3.73 gears on the offer along with all the other options you want. If they accept your offer and the Jeep has 3.21's you should be able get that jeep or one just like it for the price with the options you agreed on.

This was great info! My # was same as the one you included (2018180-2), so turns out build sheet was accurate despite only being a sport package.

That sight has been around for awhile, but it stopped with 2012's. Has it ever been updated?

Oh, let me call Chrysler real quick. I'm about to head to a dealership in about an hour, so I need to know what's up.
