Yukon Gear High Performance Gear Set For GM 11.5in - YG GM11.5-513Find parts that fit my vehicle

Big Improvement

After upgrading to 37s I was not getting in to 8th gear very often. When towing my off road teardrop trailer I was well aware of the extra strain my engine and transmission was under. Especially over the mountains. After the gears were installed everything was back to stock feel, torque acceleration etc. It's hard to put into words but it's just a feeling that everything is happier.

Placed my order and received my parts alot faster then expected. Took about a day to put in both front and rear but they run smooth and I have better fuel mileage now as well

Just what the car needed

This really feels right. Since there's no programming available yet for gear ratio alterations. Had some abs codes. Not even ford could help. Whipple has the Tomahawk programmer that can fix gear ratio, but it comes with the supercharger. Fortunately my Autel Ds808 scan tool with Can Fd adapter had the pcm relearn for gear ratio and tire size. I couldn't believe my eyes. Car is very happy now and needs new rear tires.

Top Quality Gears

I am looking for mileage and top end, not low end acceleration. Going from factory gears to these Yukon 2.73 gears has added about 5 MPG (Highway) on average to my Mustang.

Gears for my 2014 jk rubicon

Best gears for the money. Fast delivery like always and costumer service was really helpful when I called to get information on the gears.

Not great

Parts came in a Yukon package but was Timkin gears. Nothing fit out of the box. Absolute garbage

Love these works like butter for my car I put these in from the stock ones and my car runs better than I could’ve even thought or asked that it would

Good- so far

I hate to do it, but I put 4 stars. The Yukon Gears are good products, but poor packaging and missing 3-4 parts were not ideal. Has a local shop do the installation and it has been good so far- after I got it home and programmed it with flash cal. It was stuck in 3rd gear the whole way home( about 15 miles). I got it home and put the flash cal on it and told it 35-inch tires again and 4.8 gears from 4.10 gears on the stock Rubicon. Now it drives fine and is in sync so far. In the process of doing the 15-mile drives and heat cycling the gears now. Mine is on a 2.5-inch lift and 35's and was good driving for 2 years on 4.10 gears. But like one told me before I got the 4.88's when he has the same Yukon gears on his jeep, it isn't a required upgrade, but it is a good one to have.

Gears

It's a tedious job but the parts didn't fail. Requires patience and a well organized parts table. There's no room for error. I know a recheck is suggested after 500 miles so we will see whet the recheck indicates.
