Most of the miles on my 2000 are freeway miles. It did just fine at 80mph for up to twelve hour stretches. That was at stock height, though, so I don't know much how a lift would affect the ride at that speed.

 

Lol you people drive fast! I thought I was going to be ridiculed for driving too quickly, but you guys make me look like an old woman driver haha. Glad to know the xj can handle high speeds. I'll be driving all over the region for the holidays so needed something worth while in the snow but could handle high speeds besides spending a crap ton on a nice subaru...plus having the jeep for hauling wood and other crap makes it that much better

 

I've done 85 on my 4" lift with 32s. It's obnoxiously loud with all the wind noise.

I tow my 15ft boat to Canada every year 700 miles each way at 70-75mph without an issue (except my water pump went out this year and shredded my belt). Averaged about 15mph

 

I'm with you there. I'm a 65 mph guy nowadays. I've driven some of the nicest handling vehicles out there from lotus Elise's to porsche caymans to 911 turbos, M3-M5, to a heavily modified supercharged Acura NSX. I don't feel comfortable with the xj's emergency maneuver capabilities to drive one past that. It's far from a good handling vehicle and it has no reason to be.

The XJ can go over a tree down in the road and easily drive around in 6" of snow. That is the purpose I this vehicle, not high speed driving.

 

I've taken it up to about 80 but I have the airbag equipped 99 Usually put around at 65, I need my mileage yo!

 

used to rally my jeep with 4.5" of lift on 33s no issues. also no issues with higher speeds but after the axle swap she hardly ever breaks 65mph

 

Normal cruising speed for me is 85. Highway speed limits are 75 most places so its not really even speeding (flow of traffic)

33s with stock gearing means I'm in 4th until 3k rpms though, not fun

And yes, she is loud, sucks gas, hurts my back, sometimes when I hit a big bump I land in a totally different spot than expected, but at least I dont get bored
Loud stereo solves most of that anyways...
