What is the official design speed for a TJ?

I wish more people kept theirs stock and maintained the hell out of them.

That was the main reason I gave my father a 98 i had and bought a beat up 97 to build.
The 98 has been such a nice driving jeep and had not one issue in the last 10 or so years. I wanted something we could both use hunting and he doesn't like the idea of owning a lifted anything.

Though I will say he was really surprised how well my jeep on 33's drives once it had been gone through.

Every time I say this someone seems to have an issue with this and think my standards are too low, but my previous car was a little supercharged Mini that was a canyon carver. I will still say, stock TJs drive NICE. After I replaced a bunch of my front end stuff and other suspension and steering parts, I don't really miss my Mini very often on a twisty road. I feel like that's saying a lot, because before I bought one I was told I'd hate they way they drive.

It's obviously not a modern car and doesn't drive like one. It's not fast and it feels raw. But it's so nice to drive in an old school charming way. I like how everything feels mechanical and the steering isn't lightening fast like every modern car and I even like the character of the 4.0. Every time I travel and have to drive something modern and then get back in my TJ it's just so refreshing. I might get flamed for saying this but I wish more people kept theirs stock and maintained the hell out of them.

I get it. I did the mod life for 10 years, chasing more lift and more tire for really no reason at all. I am now returning my jeep back to stock. If only I knew then what I know now, I would have done things so differently. I went down the lift rabbit hole because mine came with tires larger than it should have. I should have reverted the tires and called it good. I’m all for functional add ons, but I’m not so much for mods that change the characteristics of the vehicle anymore. Hence the back to stock thing now.

It would be nice to see more stock Jeeps. Half of them out there are molested junk.
 
stock form my Lj on 31s,3.73s,42Rle it would just not reach over 103 ish and even after messing with the Limit in HP Tuners it doesn't do a thing

After Camming it, Porting the head&intake yadda yadda. It now "easily" reaches 128 on flats but it just doesnt want to go over that and i know the damn thing has the power to reach more but i learned (from what ive read) that the tranny has a hard set governor to cap the jeep at 100 but im guessing i have enough power to kinda push it to 128 and float around that speed cause it just sets itself back to over drive but if i keep stomping the throttle it just throws timing and ramps the RPM up but wham its sets itself back in OD 🙄 at 3.5k Ish Rpm

Edit- At those speeds my Lj feels great,no wobbles no nothing. It actually feels very light at that speed but its still a Toaster on wheels pushing through the air 😆 It gets driven at around 90 Mph daily in freeflowing traffic so its nothing new for me and the jeep.

Look up your tires speed rating. I doubt any of the truck tires we run are rated for much.
 
Solid little cars, still have mine. I call it my LJ escape pod. Love it when she shrieks like a banshee! Go carts for adults. :D

I absolutely loved mine. It was so fun to drive and sounded awesome. Upkeep just became a lot after I passed 100k and it just didn't make sense for me to keep pouring money into it. I would turn the wrenches myself too but man, something would go wrong every month I swear. I do really miss mine though. So many memories in that little car.

That's pretty much my game plan with Tess. I don't do hardcore offroading like a fair few here do, so spending funds on mods that suit that use would mostly be for show. I'm not really a flash kind of guy and those funds are better used elsewhere in my case.

I don't want to jinx myself by saying this but yes, my stock TJ has honestly been the most dependable car in my family. It's been the cheapest to maintain even compared to the Hondas and Toyotas they've owned. It doesn't really ask for anything from me. I'm sure if I started modding it though that would quickly change.

Holy hell what?!? I almost don't believe you. That's really fast for any Jeep! I know my governor kicks in somewhere around 113... don't ask me how I know that though :)

But yeah I'm sure you have but see what your tires are rated for. I think even the ones on my TJ right now which are all seasons are only rated to 118, something like that.

Things went wrong with mine, of course, it's a man-made consumer vehicle. But she never left me sitting stranded somewhere. My bung was a bit puckered when I purchased her as I knew I was going to be doing all of the service work myself. Having said that, with exception to a few items, the car is very well designed and fairly easy to work on.

Yeah you're right!! Mines are rated Up to 112, Realistically they only see higher speeds for about 30 seconds when im clear
Ya had me double guessing myself 😅(Thankfully) Had me checking my tires

Someday when I'm out of college and have space for two cars, I hope I'll have another. The only time mine left me stranded was when my harmonic balancer flew apart on me. Should've known. Whoops.

Waze and google maps and then both ran at the same time with me&my buddy gave me that number back when i was tuning my LJ about 6 months ago, throwing more timing,fuel here and there etc. and thats how i found out it was reaching those speeds and i was kinda surprised but i was expecting it to go fast cause i know i didn't do engine work for no reason 😆

Edit- Fast forward some time. Due to the minor engine work done and the spicy tune ive been running and too much fun! My jasper Transmission aint really having it like it used too.... No more burnouts...no more donuts on dry pavement...Hell it struggles to do a burnout on rained pavement now 😅 It'll hit 50 ish on a "burnout" but it gives no more. Thankfully it drives just fine when simply driving and still manages to reach whatever speed but it hesitates shifting into OD now

My Lj is dependable....kinda has too since its my daily

🗣 I SHALL REBUKE ANY "JINX'ING" ON YOU AND YOUR JEEP,IT SHALL REMAIN RELIABLE 🪄

They will do that, eventually. Fortunately, I replaced mine before it decided to part ways with the rest of the car.

About 6 years ago I did a deep and meticulous service on her while installing a new clutch (this is when I did the balancer). While pulling parts of to get to the trans axle, I discovered by chance that one of the many small coolant hoses had been rubbing on one of the power steering hydraulic lines (likely since it was built) and was close to rupturing. Not sure if you had to mess with yours but it's a bit of a rats nest...and these are only the lines for the hvac and oil cooler... 🤪

After I found that, I went over pretty much everything and replaced anything even slightly questionable as well as parts that were difficult to access once everything was assembled. She's still solid mechanically, save for the rear brake lines (which I need to fabricate), but she's starting to look a little rough. I've always taken good care of the car, but when I moved to MD 12 years ago (it looked almost showroom new at the time), it got vandalized within the first 6 months and she's been exposed to the elements 24-7-365 until recently when I started renting a place with a garage. Unfortunately the damage is done, the clearcoat is failing from the years of sun exposure as well as copius and constant quantites of bird shit being deposited.

Sorry for the thread diversion.

Mine has been above 90mph several times throughout it's evolution.

I haven't run the numbers, but I wouldn't be surprised is it is gear limited to a slower speed these days, though I have briefly done 85 a couple times recently.
