The difference is walk to be on the stimulate of 150 RPM. One of two people one will work fine. If you value power/acceleration over a marginal amount of engine wear and also tear then the 4.88s would probably be better.Personally in your situation I would certainly go with 4.88s. If you ever before make the jump to 35s you would still it is in okay, although 5.13s might be far better with 35s.5.13s would put you close to 3000 rpm in ~ freeway speed with 33s, which might be a little much, but is quiet acceptable.

Most tires run a bit smaller 보다 advertised size, so take that into account. I operation 2500 rpm"s at 65mph in fifth gear with 33"s and also 4.56 gears. 4.88"s should still be acceptable.
I have to examine maybe the manual trannys are various through the years and also they us have difference gears which may affect

I think the OD proportion on that calculator might be incorrect. I seem come recall the NV3550 having actually a .78 OD, not the .73 OD listed there.The AX-15 has a .79 OD therefore that would be within 50 RPM that the NV3550. Ns would use that ~ above the fall down
With my stock 3.07s, AX-15, 33s, I"m not certain the 4.0 was capable of 75 mph unless it was a big hill ns was walk down. The numerically low gearing was tough on the MPG uneven I shifted a lot and rarely did end 55 mph. Ns think I"m to run close to 1,900 rpms though as soon as I hit 75 mph, i m sorry is a little low for my preference, plus I shot to run 65 come 70.Btw mine 33s are favor 32.6" in diameter brand new. I had actually some 31s and after around a year castle measured 29" in diameter without much use.Unless you everyday drive your Jeep, I indicate numerically higher gearing. I"m going way too quick off-road v my gearing and I everyday drive mine Jeep, for this reason I"m very picky through my gearing and want to walk to 3.55s, but diesel RPM is a completely different round game.
I think the OD proportion on that calculator can be incorrect. Ns seem to recall the NV3550 having a .78 OD, not the .73 OD noted there.The AX-15 has a .79 OD so that would certainly be in ~ 50 RPM of the NV3550. I would use that on the autumn down
Yep, ns noticed that as well. I wrote to the creator of the calculator a while back but it shows up it hasn"t been updated.

I likewise was hoping to uncover the Ford/GM 10 speed auto on there. Guess it hasn’t been updated in a while
So my experience, 3.07s, 33s ~ above a YJ through a carb and also the Peugeot 5speed. I never ever used 5th gear but I did numerous US Interstate and also ran 75mph in 4th, no problem, and also I always got end 20mpg. Dropping to 3rd for hills and head winds.With my TJR, 33s, 4.10s, 6 speed, i can virtually hit 20mpg IF I stay under 60mph and NEVER floor it. No happen allowed. Anything much faster or much more agressive and also it drops come 15mpg.The beauty, beauty of 3.07s is 4LO. It runs prefer a Mustang on forestry roads and can hit 60mph in 4LO. There were number of forestry lookout towers we would certainly visit every year. Through the YJ and 3.07s us ran increase in 2nd, 4HI and also came down in 3rd, 4LO. Honestly that was means more fun than doing the in a Rubi with 4.10s.With 3.07s, I"d change into 4LO often. Through my Rubi, I almost never use 4LO.

can world tell me what the rpms are at 75 v 33s and also what gear ratio lock havetrying to figure out the finest ratio when i move over. I need to drive generally 100 miles to obtain to trails wherein I am . My 5th gears no always an excellent on freeway v 3.73 and also 31s. I do want to move to 33 in tires eventyally and also hear 4.56 is good but wouldn’t that be equivalent to what I currently have?
I have actually a 2001 tj v the 4.0 , nv3550 , and 4.56 gears. I have actually a new exhaust native manifold earlier along with new cat and also banks exhaust so that breathes pretty good. I started out v 3.73 gears and 33’s... No 5th gear usually ever. Since the 4.56 gears to be on I’ve have actually run 35” km2 on stole wheels and also now 33’s x13.5 Toyo mt’s on aluminum wheels. Ns love the method my Jeep drives through the 33’s. Drove similar with 35’s but no an ext accelerating uphill usually expected dropping to 4th which is comparable to stock. I deserve to accelerate or hold in 5th gear through the 33’s and also I couldn’t v the 35’s in any type of steeper grade. If your jeep is a daily driver or sees an ext street time 보다 trail time i say execute the 4.56 gears. If the is an extra car or will certainly be sometime in the close to future i would carry out the 4.88’s. Really think about the dimension tire you want to run and also wheel an option combo to store the weight together low as possible. When tire shopping compare weights the tires as well. Not all tires are produced equal and also the tire and also wheel combo will also affect your braking and also acceleration. Sorry, don’t go 75 in mine Jeep much more like 65 for me so I can speak to that. The not since it can’t I’m just not ~ above highways for stretches much longer than 25 mile so i usually just cruise.
