I have the complete 1.5" factory lift from my new 2021 JLUR Extreme Recon option if you would be interested that was removed by the dealer as soon as it came off the truck. The Jeep came with 35" tires and I measured the difference between stock as delivered and when I added the 2.5" Mopar lift and I gained exactly 1" from the new lift. Thus I know the factory lift is ~1.5" to handle the 35" tires. I have all of the trailing arms, sway bar links, spring pads, longer red shocks, springs, and the stabilizer that are brand new.
