    Stronger sway bar will help with your handling in the wind. I got the ORO swayloc. Instantly improved my handling… only lost about an inch or two of flex on the disengaged position from completely removing the swaybar.

    The new 8 speed is nice. I have a 2015 automatic with 4.88 gears and 35s. Mine gets 14 mpg running 2,900 rpm at 70 mph.

    I have 4.88 ratio' in my Rubicon. However I have an L-83 Gen 5 V8. I'm calculating 19.3 MPG with the GMC 8 speed transmission. The tire size is 37"". RPM at 70 is 2200. 2 door.

    Buckee’s is growing. On the way to Orange Beach, AL., we needed to turn south off I-10. Well, what do we find?

    Thanks for the video, I’ve been debating between 4.56 or 4.88 for my JLU with a 2.0. Not sure I plan on going 37s as 35s feel like plenty for now for my wheeling.

      @@alfa8822 Nah my jeep stays very light most of the time. If I go out to the trails at most it’s some tools, food, and water. Working getting a few spare parts to keep in the stockpile in case anything breaks while i’m away from home. Mostly shafts and tie rod ends I wanna have ready.
      That and with a 2.0, IF i do go to 37s it’s not that bad RPM wise apparently. A few XRs on the forum still get 8th gear with 37s and the 2.0.

      I went with 4.56 and now wish i would have went with 4.88's. I'm thinking of spending the 2500 to go to 4.88's. I do a lot of mountain pass driving and off road driving in the mountains i feel like i don't have enough gears some times. I own a 2014 Wrangler JKU sport Yukon limited slip in the rear and Eaton turetrac up front.

    It's pretty funny we started talking about Bucees on the show, and many didn't know what it was. Listeners were most interesed in Beaver Nuggets! lol Beaver Nuggets were a big hit at a Jeep Talk Show Off-Road Texas event. :D

    Hello, like the video! Have you noticed any jerking when slowing down? I’ve heard a few people say that they have had jerking when the transmission shifts down after going to 4.88s

    • @caseycrawls4466
      @caseycrawls4466  10 หลายเดือนก่อน +2

      No, I’ve not noticed anything like that. Drives very well with the 4.88 gears.

    I have the same tires and gear ratio on my 2024 JLRU… I’m getting about 15.8 miles per gallon… ( Mostly driving in M8/D8)…I think I would do better if I had mostly miles and miles or flat terrain, rather than the uphill and downhill that I constantly have to deal with here, in New Brunswick, Canada…

      I've found that manual calculation is a bit less than what the computer says. I'm probably around the same as you.

    Great video! Think 37’s will be okay with 4.88’s? I’m looking to get the 2 door JLR in a 6 speed, V6, but order with 4.88’s and run 37’s.

      Thanks for the comment…I really like the 4.88 gear and, yes, it would be great with 37” tires. I wanted the flexibility to move to a 37 when I installed the gears, that’s why I went with this gear. Good luck with your Jeep…I love this little 2 door!

      Sorry for the late response...I went to Insane Offroad. The owner, Tommy, does a great job. I've had to buddies get their gears from him with good results. Highly recommended. He moved his shop and is not located off I45 North.

      My 2014 JKU wrangler sport had 3.27 gears from the factory. Do a Vin number look up on line for Jeeps and that should tell you what gears you have or go a Dodge dealer let them run the vin and can tell what the gears are. You call any Dodge dealer too.
