The max tow on the sport has 4.10 along with the dana, so the short answer is yes in that one can order the max tow and get the 4.10 with it in a Sport or Sport SHello,
Will 4.10 gears from a rubicon gladiator fit my sport? I know they have the same 44 dana axle.
Thank You
This.The long answer is:
With all the labor and expense of changing the gears front and back, the last place to cut corners is to install someone else's used take-off gears.
Also, that's a fair amount of money and work for such a minor gear change. In a perfect situation, you're gearing up to bring the overall gear ratio back to stock with stock Rubicon tires. Any taller tire than that and you ideally want a taller set of gears to go with it.
Reuse the bearings? That might be an even worse idea than used gears. I've never done a Dana 44, but usually the bearings and races are press fit. They are meant for that to be done once. IF you get them out without distorting or damaging them, they still arent going to hold like they are supposed to. And bad things happen when parts spin that arent supposed to.Also, even with a used set of gears you'll need crush sleeves & shims, and I guess you plan on reusing the bearings? Sounds sketchy to me.
Exactly my point. Perhaps I could have worded that better.Reuse the bearings? That might be an even worse idea than used gears.

OK, 2 things. While 4.10s with 35s will be fairly close to the overall ratio you have now, You and your Gladiator would be happier with 4:56s. That would help just enough with the added tire size and weight to feel about the same, drivability wise.Thank you, my brother in law is going to do it . I'll be buying the other stuff new. I'm currently running 35s and don't plan on going any bigger.
Thank You IamPro2a, I completly understand your concern, he is a good mechanic, worked in many dealerships and has his own shop. I have trust he knows what he is doing and won't screw me over. He better not or I'll do the same to his sisterOK, 2 things. While 4.10s with 35s will be fairly close to the overall ratio you have now, You and your Gladiator would be happier with 4:56s.

Second, I'm sure your BiL is a great guy and a great mechanic, but is he a differential specialist? I've worked as a mechanic, (still part of my job 40yrs later) and also spent many years working in an automotive machine shop. I have built hundreds of engines from bare castings up. Setting up a differential is still one of the only jobs I will farm out. It's more than just following directions, proper tools, and attention to detail. Setting up differential gears is also part art, and part magic. You can tell me 100 times what the tooth engagement pattern in the marking compound should look like, but making all the adjustments in all 3 dimensions to make it happen? That comes with LOTS of practice.
Sure, I think most of us with enough time will get it to work. Will it sing on the highway or whine when you let off the gas? Probably.
Will it last the life of the vehicle? Probably not.
Is it a chance I'll take on a $50k-$70k personal vehicle? Twice (front and back both have to be done)? Nope.
Ok, so let's assume he can do it.Thank You IamPro2a, I completly understand your concern, he is a good mechanic, worked in many dealerships and has his own shop. I have trust he knows what he is doing and won't screw me over. He better not or I'll do the same to his sister
Right. The stock Rubicon with the stock 4.10s has 33" tires. Hell, even my Sport S with the Max Toe has 4:10 gears with the same size stock tires as the OP's.Ok, so let's assume he can do it.
There is still the issue with 4.10 not being deep enough for 35s.
mathematically, you are correct. I think 4.15 or something would be exact. But real world is different. You have bigger tires, they weigh more. They have more rotational mass. It takes more horsepower to get them rolling ( and stopped). That adds stress to the axles and differential. Like I said, even the Max Tow Sport gets 4.10s with the same 31.5s you have, and the Jeeps with 33s like the Rubicon all get 4.10s stock. There's a reason Jeep uses 4.10s for 33" tires.I followed the gear formula and its closer to 4.10s. Why do you say not deep enough for 35s? I'm new to the whole jeep life
