Best Gear sets for my Dana44’s

I have 35’’ tires on my 2017 JK with 4.10 gears and auto trans and performance is sluggish for on the the line and up hill. Mileage is terrible at under 13 mpg. My jeep is mostly on the road but she does occasionally get in the sh1t. The jeep doesn’t seem to shift properly either.

Ok so now I am looking at changing the ratio to 4:56 or I don’t know. Hoping to get some advice on this - the gear ratio and which manufactures to consider. G2 or USAlloy or ?

Much appreciated.

Most gear set are made at the same manufacturing plant. Most aftermarket jeep parts houses run deals on gear sets with installation kits, pick one. Have you recalibrated for the tires?

The only thing done when the tires went on was to recalibrate the speedometer. Should look into a programmer or?

I run 4.56 Yukon gears with 35s and it performs well. With the 3.6 you should be looking at 4.56 or 4.88 gears.

I run 4:88 gears with 35s and auto trans, response is and if fun great in the mountains but the engine is turning 27-2800rpm at 70mph. I do not what kind of gears I have, it was already done when I bought the jeep.

You should reprogram for actual (measured) tire diameter before you do a re-gear. A 2017 with 35s should be fine if recalibrated.

I have 4.88s in my 2018 JKU with 37" Pitbull Rockers. It does pretty good, but, I have 4.56 in my Wife's 2015 JKU with 37" Toyo MT's and it seems to perform better. Her 2015 has always seemed much peppier than other 3.6 JKU's I have owned/drove. The Rockers do have more resistance than the Toyos, that is probably a contributing factor as well. My 2018 came with 3.73s and once I put the Pitbulls on, it was a dog.

@SoK66 is speakin' truths ; I ran 35s on my '11 Unlimited with just a tuner and the factory 4.10s for several years . Unless you have extremely heavy tires /wheels combo, you should not have insanely poor performance.





I chose Yukon 5.13s from @RiverCityOffroad Marcus and had them cryo'ed when I went to 37s and lockers.

I put 4.10's in my 2013 JK and was running 33.5" tires. That was a big performance boost over stock but when I went to heavy BFG KM2 35's I wished I had 4.56 or 5.12.

Shift points matter! Get a tuner and correct your tire diameter, your mileage and performance should get better.

We would suggest 4.88s, or possibly even 5.13s - Nitro Gear & Axle Gear Packages are awesome BTW. We'd love to help you when it's time.

Suggestions would be 4.88 if you are a moderate weekend wheeler, who wants to stick with 35s. I'd be go 5.13 if you have heavier 35s, or plan to up to 37s or wheel some on the hard side. If you ever see yourself going 40s I would do 5.38

Most are made in China - Not Nitro Gear & Axle, however
