Yukon Ring & Pinion Gear Set For Dana 35(M200) for Jeep Sport/Sahara 4.56 ratio 24-Spl Standard Open
Put 33 or 35 inch tires on a JL Sport or Sahara and the factory rear ratio stops working: the eight-speed hunts between gears on the highway, hills pull it down a gear or two, and fuel economy drops. The Yukon Gear & Axle YG D35JL-456 is a 4.56 ring and pinion set for the rear Dana 35 used under some Wrangler JL Sport, Sport S and Sahara models, the 200 mm axle also called the Dana 35 M200. It is a new set with a 24-spline pinion, cut for the JL rear with a standard open carrier.
The pinion gear takes power from the rear driveshaft and turns the ring gear bolted to the differential carrier. The number of ring gear teeth divided by pinion teeth is your axle ratio. A 4.56 set turns the pinion 4.56 times for every turn of the axle, so the engine sits higher in its power band at a given road speed. That is what gives back the acceleration and the gear choice the factory had with stock tires.
The JL Dana 35 is a newer design than the Dana 35 that went under YJ and TJ Wranglers. It uses a 200 mm ring gear and its own pinion, so gear sets for the older axle will not fit it. JL Rubicons and some Sport and Sahara models use a Dana 44 M220 rear instead, which takes a different gear set altogether.
Check which rear axle you have first. The axle tag on the rear housing or the build sheet tells you whether the JL has the Dana 35 M200 or the Dana 44 M220. Then find the current ratio on the tag or the window sticker; JLs were built with several ratios, and both axles must end up with the same one. If you have gear noise rather than a tire size change, drain the oil and look for metal, spin the pinion by hand for roughness, and paint the gears to read the contact pattern. If you are reusing your gears, a Yukon JL Dana 35 master overhaul kit may fix the noise without a ratio change.
Yukon lists this set for the Dana 35 200 mm rear of the 2018-2019 Wrangler JL Sport, Sport S, Unlimited Sport, Unlimited Sport S and Unlimited Sahara, 4WD, with a standard open carrier and a 24-spline pinion. Later JLs with the same Dana 35 M200 rear generally use the same axle, but confirm the axle tag and your current carrier before ordering. It does not fit any JL Rubicon, the Gladiator JT, or a JL with the Dana 44 rear. If you have an aftermarket locker or limited slip in the Dana 35, confirm that carrier accepts the 4.56 ring gear. Send us your year, trim and VIN if you want us to check. More axle hard parts are in our hard parts collection.
Building the rear for more abuse? A Yukon Hardcore nodular iron cover protects the gears on rocks, and the Eaton ELocker for the JL Dana 35 adds a selectable locker while the axle is apart.

No. Every JL Rubicon uses a Dana 44 M220 rear. This set is only for the Dana 35 M200 rear found under some JL Sport, Sport S and Sahara models.
4.56 is a common choice for JLs running 35 inch tires, and some 33 inch owners who tow or wheel heavily also use it. Your engine, transmission and how you drive all matter, so check with a gear ratio calculator using your exact tire height.
Yes. Front and rear must have the same ratio or the drivetrain will bind in 4WD. The JL front Dana 30 needs a matching 4.56 set.
New carrier and pinion bearings, a pinion seal, shims, ring gear bolts and a crush sleeve. The Yukon JL Dana 35 master overhaul kit includes them. Plan on gear oil and a speedometer recalibration.
Drive gently with no towing or hard acceleration for the first few hundred miles, let the axle cool if it gets hot, then change the gear oil to remove the break-in material.
