Swapping gears in the 3.7L V6 QT1, I am completely surprised by the lack luster response to this news. I guess there are a lot of owners here that say they want to be able to swap out gears, but when it comes down to actually doing it the numbers fall short. And we wonder why aftermarket suppliers are slow to non responsive to our requests for more products.
07JeepXK, how about an update on how your friend is doing with the 3.73 gears?
Jays WK is driving great! You can totally feel the difference with the new gears. It's a totally different jeep now and has no issues turning the 33x12.5 MTs. The only down fall was he lost his one touch lane change for the turn signals that was programmed with his AEV module. The WK won't allow him to run both programmers but thats something he can live without. He drove it for two years prior to being lifted without that option. It won't effect those who already have that programed on their jeep.
We had the same issue with the Air Flow snorkel. When there was talk about producing one for the XK everyone wanted one. Now that its been out for a few years there has only been about 4 kits sold in the US.
And a XK :) I have 3.55 gears on the shelf ready to go. But now that I know I can install gears, I'll place that on the back burner and install my QT2 transfercase. I've bench tested the program for it and it looks good. My biggest concern is will it throw "gear ratio" errors when I go into low range? Reading the service manuals, I'm assuming not, if I do a few things before shifting into Low. Turn off ESP, keep the Jeep in 1st gear and not go over somewhere around 25mph. We'll see.
It all sounds good, with 33's he has got to love those 3.73 gears!
The Jeep dealers got me to where I am with 3.55s and you know the story. But with that, Criket, in a round about way, benefited from all that, install those gears bro!
With my 31.7" tires and the QT2 transfercase, I think my 3.55s will work, but yes 3.73s would have been better. Criket, if you decide not to install let me know, I may be interested in them.
Toby can you text me some time the total cost for front and rear gears 3.73 gears.

Jays total cost for a front differential with 3.73s from a junk yard, rear motive gear 3.73 ring and pinion and Hypertech Speedometer Calibrator was about $1200. That's money well spent and his gas mileage even went up since its easier to turn those 33x12.5 tires he has. Labor was free though since we did all of the work.
