6 speed gear decision input needed

[Apples491]

Since I have all you 3 pedal guys here, have any of you used a throttle controler? My biggest complaint with the manual isn't the manual, it's the f@cking delayed throttle responce. Rev hang sucks and not being able to rev match on the downshift drives me freaking nutty.

Get it tuned.

Throttle controllers are garbage and can cause havoc on a Canbus system. And they won’t fix rev hang. Even the “good” ones. The cost of one is a third of the way to a custom tune which will give you all the throttle response in the world plus 400 other benefits.

Rev hang is addressed with torque tables, spark timing, and cam timing.

Completely different vehicle after tuning.

I have a Sport S (3.45 diffs ) 3.6/6-sp. The combination of the gearing, poor throttle programming, the problematic high valve lift at 1800 &2800, and generally low torque below 3000 was disappointing.
A PedalMonster really helped but only with initial takeoff. Just get a tune, instead.
Brad’s tune also corrected the throttle response in addition to correcting other factory tuning deficiencies. 6th gear is now usable.

We decided we’re going 4.88’s

Thanks for the input, I'll start lookig into a tune.

That's what I was afraid of. I'll go dive into your yotube channel, thanks!

I opted for the 4.88 (6 spd). I liked the gearing much more when I went to 37s.
I would 4.56 is more ideal for 35s but since regearing is expensive you really can get by with 4.10s. If money is no issue, go with 4.56.

I’m about to get my wife’s Jeep regeared. Hers is also a 6 speed but a sport. Her Sport has my original Rubi axles under it with the stock 4.10’s. We recently did a small lift and 35x12.5-17 tires on my original Rubi wheels. Hers will never go bigger than 35’s and the 4.10’s just don’t cut it on the highway. We recently went to OKC from Amarillo and was in 5th pretty much the entire just to be able to go the speed limit of 75. 6th couldn’t maintain that speed even on flat road.

Those that have 35’s on a 6 speed, 4.88 or 5.13? I’m leaning towards 4.88 for the bigger pinion, but that’s not a huge deal on hers it’ll see some dirt roads and light trail use

I went with 4:56 and they are ok. I live In a flat area though. I would have rather gone with the 4:88's . I think 5:13's would be too low for 35's unless you are going to use it more for off-road.

My Rubi has 5:13’s and 35’s. That’s why we didn’t drive it out there, it’s rung out a bit, but my Rubi is going to 37’s or 38’s soon and that was the plan from the start. But this one will stay on 35’s which is why I was wondering what’s recommended.
