Explain to me why reinforcing your axles helps you go to 100??????? I swear the level of retardation for jeep owners has gone to astronomical levels.

To the OP, Most of the problem with your jeep being a turd in the mountains is the thin air and the weight of the tires is killing you. A 35" M/T on a regular wheel will be 100lbs a corner. Switch to a A/T tire and save weight where it counts, reducing rotational mass will be the best mod you can do to get back some of the drivability.

So the axles don't bend when the hop begins. Duh.

Cs. So I don't see my tires roll past me on the highway. Would you say something else if I told you I had dana60s? Don't know why it was such a problem that I said I reinforced it.

Along with gravity and grades in the 6=8% range. My stock JKU Sahara with 4.10 gears struggles up these grades as well.

Because reinforcing your axles has zero to do with you going 100mph.

So your theory is that if you're running 100 mph and hit a pothole, a stock axle will take the hit just as well as a reinforced axle? Hmmmmm.

I'm sure it's got a better chance of surviving the hit than a stock Dana 30 on 37s.

My '09 JKUR is running 37s with 5.38s and does well here in the SW Colorado mountains. The occasional gear drop to near redline heading up to Silverton, but otherwise fine. Manual front hubs does help in that regard. When the 3.8 decides to give it up we'll look into a V8.

Nobody said shit about a pothole or obstacles. And I quote....

I can hit over 100mph. A bit sketchy but had my axles reinforced.
He is implying that its safer to do 100 in a jk because his axles are reinforced like it makes one half ounce of difference.
