Are you comfortable at 80 mph in your YJ?

My comfort level gets checked at about 72 mph, starts dropping at 75 and disappears completely by 80 mph. I usually stay at 80 just long enough to pass.
The wind has a lot of influence also. We aren't very aerodynamic, are we?

I cant imagine being comfortable in a YJ period. they just weren't built for comfort at any speed and 80 is suicidal. JMO.

Speed limit here is 75 and mine seems to do fine there and maybe a touch more to pass. We do get big wind storms here from time to time and that will slow the Jeep down some. New springs and shocks so that may make a difference. Waiting on front end steering parts before alignment. Then it will feel like a slot car, I am sure! (HA! Sarcasm)

Bridges are what scare me. Even at 70mph it likes to bounce hard and gets tossed when crossing expansion joints in bridges. 65 is max for me.

80 would be a no go for me. It is straight and 'relatively' smooth but all of my senses are screaming no. I feel that if I did DD it then I'm sure 75-80 would eventually be less uncomfortable. Of course I wouldn't DD anything that old.

With all this crazy talk I went out and looked at my speedo.
Sure enough, it reads 50, then 60, then ludicrous speed, then plaid.

I do 80 - 100 with no problem. Not for 200 miles in a stretch, but 10 to 20 min. there is no problem at all. If you build it as rock crawler, don't do it.

Mine rocks like a dingy at 70-75 since I removed the front traction bar. I have no desire to even go over 70 anyway, doubt I can do 80.

I will feel easier once the ball joints, tie rods, wheel hubs, all that are replaced.

Oh 80 is almost impossible to achieve, Wind has to be just right. You would have to be going down a very steep grade to hit 100 in one of these

80 isn't bad at all on 4 lane roads, speed limiter won't let me past 98.

Still running an anti-swaybar, and I've considered putting the track bar back on the front axle. 2.5" soft ride and 30" tires on stock wheels.

Added a bunch of Velcro to attach the Safari top to the sport bar bracing overhead, dramatic improvement in top flop at speed.

80 MPH in a YJ???

Sounds like the title to a 1974 Charles Bronson movie.

Good Luck, L.M.

I can verify Manny’s YJ has no problem winging that LS and 4.10’s to 100. I had the opportunity to drive that Jeep, and I can assure you it runs hard and is stable. On a side note, that entire Jeep has “Craftsman” written all over it, and I don’t mean tools. Old school pride in the engineering on that thing is evident everywhere. That old school craftsmanship and engineering comes from Manny himself. He is a knowledgeable and capable guy who takes pride in everything that he does. Plus, he is a Cool Human.

We will get that thing dialed in Bud! Mine is solid as a rock at 80 (although the relatively short wheelbase and 35” tires do not leave a great deal of room for error), so yours should be even better!

Mine maxes out right around 77 mph. That was day 1 of owning it, driving home on I-5, drafting off of a big rig. Mind you I had hard top and full doors on as well back then. The other week I was driving home from Deer Camp 2019 with no doors and a bikini top… I didn't even want to take it above 65. Got home and my ear were ringing!

I understand once you hit 85 you're no longer driving, you're merely pointing in the direction of the crash.

I consistently drive 70-75 mph on the highway and it is rock solid one hand affair. Going 80+ and it is still stable.

Key is to having everything chassis wise dialed in. No sloppy whipped bushings, steering components, whipped shocks and of course a SWAY BAR. I know there are many on here that say scrap the sway bar and this is one of the reason not to. It works as intended! Leaf spring front suspension in no way counter reacts body roll. That is the job of the sway bar.

And last for all lifted jeeps you must have corrected positive caster. More is better for stability. I’m running 8* which is a little more than factory spec.

With 4.88 gears and 35" tires hell no, I keep it around 65 and maybe 70 if I need to pass but otherwise I am a right lane rider.
