Jeep Wrangler 4High vs 4Low

[ChrisW]

Not sure if you caught my earlier post - but I had the same issue, and my solution was to change the ring and pinion (final drive ratio) - aka regearing.

Yes, I am aware the Rubicon is not suitable for four low which I mentioned earlier, so perhaps I should be changing my car or changing my transfer case as I am struggling to see this is a technique issue since it is related to RPM and torque. This of course contradicts all that has been previously said on this thread about for low being unnecessary, even at an expert level.
 

I dont think that's a fair conclusion tho... you're asking in a Carnity Forum but applying it elsewhere. Carnity Intermediate is not the same as other club's intermediate or experts. So what works here may not apply elsewhere, and it all depends on the car. Granted, you're asking for Jeep Wrangler, but when you're leading a drive, you get a sense of what works for the whole convoy, and the Seniors of Carnity have given that input by suggesting 4Hi. This I concur, all my 100 drives with Carnity I don't see a need to go 4Lo except to self-recover.

Once when driving with friends outside this club, we did notice my friend's Jimny was struggling in certain climbs we're doing, so I asked his permission to try out his car and him in passenger chair. After various trials we find that the Jimny performs well in climbing with 4Lo instead of 4Hi, and his Jimny was a manual.... thus we have a combo where some ppl drove in 4Hi and some had to go 4Lo, whatever works for that individual driver...

So all these 4Lo vs 4Hi just depend on the car and the kind of drives, no one formula for all kinds of drives and for all clubs everywhere...

 

Jimny changing to 4Lo to get out of bowl
