Ah, gotcha. To be honest. I’m not sure. I had a shop do the regear. They’re from Yukon gear and axle and came in a kit. Sorry I’m not more help!!

Got my appointment on Tuesday for the jeep to go in for 4.56 gears from my local shop. I should have it back by Thursday. I’ll post up here my thoughts after.

Quick review of the setup:
6 speed, 3.6l
Tire: 285/70r17
Stock rims
Rubicon suspension
Smittybilt winch, LOD front bumper, Roam rock rails.. lot of added weight.

These 4.56 gears are great. I’m only 40 miles into my break-in period so I’ve been going real easy on it. I will say the torque is great. The quicker response is real nice. I can’t wait to change out to 35’s as it should be the perfect setup. I would highly recommend this setup to anyone looking to go to 35’s and gain back the 6th gear.

I had Zeus Offroad in Burnsville, MN do my work. I would recommend them to anyone in the area. I went with Yukon gears.

So I'm getting ready to pick up a '21 Willys Sport 2 door manual 6 cyl. I'm going with a 2" Mopar lift & definitely want a set of 35s"
How much should I expect to pay for re-gearing & where to get that done the right way? Jeep dealer? Will that screw with my warranty? I really am set on the Willys Sport but want the 35s & also want the performance. Thanks for responses!!

you definitely don’t need a rubicon?

i would go to an aftermarket shop, the dealer will charge a lot and thats probably not something they specialize in.
warranty is a touchy subject.

im happy with my manual trans, 35s and regeared to 4.56. Going to add a rear ox locker soon and if i go to 37s ever I’ll upgrade to a front 44 of some sort

4.56 vs 4.88 then?
If I ever decide to go 37s can I assume either of these will be ok?

I have 4.56s and 35” tires with my 6 speed. To be honest if I did it over I’d go 4.88s with the 35s, and would certainly go 4.88 or higher for 37s.
I had my 4.56s for a year with smaller 33”s and thought that combo was fantastic. Great gearing on the highway, reduced the wide spacing between some gears and fuel economy was not affected much compared to stock gearing and 33”s. Also the higher revs on the highway were not noticeable to me (soft top).

If I ever do it, 4.56 would be the way I go. It just isn't bad with 35's and 4.10 to pull the trigger on that kind of expense. Maybe if I lived closer to mountains I'd do it.

I would have it done by an offroad shop that is known for doing built up rigs. Checking with local clubs could help you figure out who meets that need. Every area is different on prices, but I’d expect somewhere between $2k to $3500 depending on gear brand and labor costs. My recent job just cost $2600. As someone who’s done their own gears before in the past (Put 4.88’s in my TJ) that money was well spent. Gears are a PAIN IN THE ASS which require special tools and a lot of time. I’ll do most things myself, but regear is not one.

Best of luck!
