X vs Sport

Have to agree. Add lockers to any TJ with the big wheel option which gives you a Dana 44 rear and 3.73 ratios.... and you've got a great off roader, for way less money than a Rubi.

The 4:1RockBox is a real pain any where except crawling up a waterfall. I much prefer the 2.72 reduction every other TJ has.
So you're driving a Rubicon because...?

I tow a trailer 12K miles a year and the Rubi 4LO works when you want to go real slow, like reversing up or down a steep driveway with a 2K# trailer.

I have often thought about buying an LJ for the extra towing capacity and trading transfer cases to make the Rubi my toy, the LJ my work truck.

Thx again for all the info. Secondary question. Assuming I find a rig with 3.73 gears, it looks like I can go to 32s or 33s and still be within the "highway driving" recommendation range on the guide I found on Quadratec site; however, the guide shows increasing to 3.91 or 4.11 gears for a better "daily driver" overall performance. If my new girl is going to spend most of her life on pavement, prob 90%, is it worth the $ of regearing?

Secondarily, to my secondary question, do I need to consider having the odometer and speedometer recalibrated to account for the tire size and/ or gear ratios changes?

Thx again!

Pay no mind to that, or any other, "chart" for gearing recommendations. They are notoriously under geared and/or based on a 1:1 final drive. Take the advice of those experienced in gear swaps and to those that use said gearing.

Ok, so I think I'm almost there, at on understanding some of what I want/need in getting my new girl set up for success and happiness...last one on this topic (yay right!? - sorry), if she is gonna be mostly an on the road girl is there a need to be concerned about upgrading to Dana 44? Thx again and hopefully sometime soon (very soon) I will starting a new thread all about my new baby girl!

probably no need to upgrade to a Dana 44. If you are on pavement mostly, don't want a locker, and run 32's, than a Dana 44 is just extra expense

No way is it worth regearing from 3.73 for 33s on the street. I have 4.10s and wish for 3.73s every day. Gearing SHOULD be geared for power in DIRECT , not OD. OD is to quiet the ride, drop the RPMs when you do not need the power. It is EASY to gear down for a hill.

That is why OD became common 40 years ago. Not to make another gear for power, to add a bit to your gas mileage. Listening to the guys saying "yeah, you need 5.38s for the street"? Do some research on your own. Some of the hottest cars in the world make top speed down a few gears. Audis A8, 8 speed tranny, hits top speed of 150mph in 5th gear. The other 3 gears result in slower top speed but better economy, emmissions and a way more comfort on the highway.

Depends also on your TJ. If it is an SE..... You need to gear for performance, 4.56 or lower just because there is no surplus of power. But the 4.0L has plenty of power to deliver great performance with 33s and 3.73s.

Worst geared car I ever had was a 1970 TA, 455 & 4.10 ratio. Best was a 1975 TA, 400 & 2.73 ratio. All about balance but if you daily drive on the street, do not gear it for the trail. 4LO will give you plenty of off road gearing.
