Good day,
It's now time for my jeep to get new gears. It's way to sluggish on the hwy with the trailer Behind.
Before I ask let me give you some info of my jeep and a trailer.
It's an 07 JKU Rubicon (manual) with factory 4.10 gears and 4:1 transfer case.
In the last 3 years I've modified it and added extra weight:
35" Goodyear Wrangler w/
17" alum wheels (9" wide)
Front mid width bumper
Winch
Rear full width bumper w/ tire carrier (full spare)
Plus a trailer
It's an M101 CDN, with 130lb lid, and matching wheels and 35" tires, RTT, Awning, nose box. (about 1300 lbs dry) My jeep is a second vehicle and I use it mostly for my camping/fishing/hunting/expo trips.
Now, when I'm on a hwy, I found my jeep is extremely sluggish at hwy speeds. My 6th gear is pretty much useless And im getting really crappy mileage On a flat hwy, no hills, well under 65 mph (95-100 km/h) , I'm getting 13.5-14 mpg (16.5-17 L/100 km) towing my trailer (not fully loaded) and 2 people in the jeep,
So I need your opinions in this: Will re-gearing help me on a hwy speeds? and will they help to improve my MPG? I've done my fair part of reading on Jk forum an such, and it looks like folks there go for really high gears only to be able to rock crawl and don't really care about Mileage. But for me, I love exploring and do it as much as I can, but with gas at $5+ a gallon ($1.40 per litre) I really care about mpg.
So what gears do you think should I go with? Is 5.13 too high and waste of gas on a hwy? Or is 4.88 just enough for my needs?
I'm stuck and need an advice,
Thank you. Sam
