I just bought a 2018 JL and I'm looking to get a opinion on the best lift for on and off road driving? I'm also on a budget i have about 2500 max to spend.

Welcome to the forum!

In this day and age, $2,500 will buy you two left springs and two tires.

If you shop around, you can probably get a Mopar lift, installed, for $2,300. You will need another $2,500 for wheels and tires.

Good luck.

I have a set of 35 12.50 setting in the garage right now, JKS has a 2.5 as well. I like that this kit has a lot of upgrades that come with it. I heard its best to at least do lower control arms in order to get the best caster on the front axle which this kit includes that. I just want to get the best kit that will take care of all the jeep problems that usually come after you lift a jeep. I used a Zone 4" on my tj which I only drove twice after i lifted it and then sold it so I never took it off-road.

The 2.5 is the preferred choice for 35's for sure. As for gearing, the new 8 speed trans makes the 35's on 3.45 gears doable. It's not good for towing, but daily driving is fairly normal...

That 2.5 J-Connect kit with the control arms is $2500+....

This is why I am not inclined to be looking at putting on larger than stock tires anytime soon, because I will be towing a small cargo trailer, fairly regularly (once a week) during the warmer months, and sporadically during the colder months.

The 8-speed automatic indeed does a very good job is masking the impact 35s have on the stock 3.45 gears.

The only reason I noticed what was actually happening was due the dismal 12/14 MPG, and because I had configured my dashboard display to show on what gear the transmission was in any given moment.

It appears that Rubicon’s 4.10 gears handles 35s fine. And perhaps EcoDiesels and 4Xe with the 3.73 gearing. But I’ve read of many other JL owners with 3.45 gearing that kissed goodbye to both the use of their 8th —and 7th— speed, and to their MPG.

It also appears that eTorque minimizes to some extent the impact that 35s have on MPG. However, I don’t know if eTorque also helps retain the full use of all the auto’s 8 speeds.
