Had a local shop install the kit. After reading several reviews I was worried about receiving a lot with the wrong parts. All of the correct parts were there and took the shop a day to have my gladiator back. Labor cost was $2400. Went from 3.73 to 4.88. Currently running 37's and was finally able to see 7th and 8th gears. Power restored and a little more mpg. Overall I'm very happy with this purchase.

Kit was complete as in the description but did come with the wrong bearing for the rear yoke. My shop had to order a new bearing from Mopar to complete the install. 2 days turned into 5 day install. Other than that everything went smoothly.
I have 2019 wrangler sport with 3.45 and want to replace my 245/75/17 with 285/70/18. What ratio do you recommend.
Quadratec
A 285 70 R18 Tire most commonly will measure 34.8" so 4.56 is likely best. Be sure to refer to our gear ratio guide for larger size tires http://www.quadratec.com/c/reference/best-gear-ratio-when-adding-larger-tires Thanks for your inquiry.

So, I have a '18 JLUR. I went to 35s and added an aluminum clamshell RTT, so the jeep got kinda heavy and im currently in the 15 MPG range and rarely see 8th gear. I dont know if I should go 4.56 4.88 or 5.13. I'm looking for mostly mpg savings as I actually do well offroad now, but will also take my overland trailer out, about 1,500 to 2000 lbs depending on loadout. I would like to see 8th gear again and a couple more mpgs. Any advice?
Quadratec
With 35's and needing added power for weight considerations, 4.88 would be the most appropriate selection. Thanks for your inquiry.

Would you want 4.11s for 33 inch tires?
Quadratec
Yes. Anywhere between 4.11 to 4.56 for 33 are good options depending if you are seeking more economy with the 4.11 or more power for towing a 4.56 could provide. Thanks for your inquiry.
