mvusse Posted June 15, 2015 Share Posted June 15, 2015 I have 32s with a auto and 3:55s and it is a dog. Can I run 80? Yes. Will I do it for extended periods of time, nope. I will eventually drop 4.10s in my diffs. I used to run 33s on the stock 3.55 axles. Ran 80-85 for 400 miles like that headed to Badlands Offroad Park.

ggcnash Posted June 15, 2015 Share Posted June 15, 2015 Had 3.55 axles under mine for awhile with 255/75/17 32" tires it really wasn't that bad I could run 80-85 fine and faster if I was brave enough. The only thing that bothered me and forced me to go to 4.10's was the constant downshifting on the interstate with the aw4. Link to comment Share on other sites More sharing options...
Knucklehead97 Posted June 15, 2015 Author Share Posted June 15, 2015 I never drove his fast enough to need 4.10's on the interstate. Ill probably end up getting 3.55's in mine simply because they're easier to find lol Link to comment Share on other sites More sharing options...
Rockfrog Posted June 15, 2015 Share Posted June 15, 2015 A 5spd and 3.55's is a completely different beast than an AW4 and 3.55's ... Link to comment Share on other sites More sharing options...
Knucklehead97 Posted June 15, 2015 Author Share Posted June 15, 2015 Beast in the good or bad way? The way you were talking about 3.55's and 32's it seems good. And I'm only doing 31's, maybe 32's eventually. Link to comment Share on other sites More sharing options...
Rockfrog Posted June 15, 2015 Share Posted June 15, 2015 Yeah the 5spd needs less gearing help to do the same job. Less parasitic loss with a manual trans. Link to comment Share on other sites More sharing options...
Knucklehead97 Posted June 16, 2015 Author Share Posted June 16, 2015 Just another reason a stickshift is better lol Link to comment Share on other sites More sharing options...
Pete M Posted June 16, 2015 Share Posted June 16, 2015 in the world of big tires, the manual trans needs MORE gearing help when starting from a stop. otherwise the clutch can suffer immensely. the torque converter in an auto is a good bandaid that makes up for a lack of low gears. 3.55 geared axles are so plentiful in the junkyards that no one should have to settle for 3.07s. 3.07s suck.

Even me, with crappy junkyards, can get a set of 3.55 geared axles from a Cherokee for around $250-300. Link to comment Share on other sites More sharing options...
FrankTheDog Posted June 20, 2015 Share Posted June 20, 2015 But if a 3.07 geared D44 falls in your lap, that's what you run with. That being said my cherokee on 31's now and 32's previously is great on 4.10's I have 210k on the clutch. I wouldn't want any taller gears than that for any reason. Summertime averages 20 mpg. That's all around driving. Yes, the speedo has the right gear in it. Link to comment Share on other sites More sharing options...
jimoshel Posted June 20, 2015 Share Posted June 20, 2015 There was a car built in the late forties, early fifties with a manual transmission and fluid clutch. I think it was a Chrysler . Maybe we should think about bring ing it back. Link to comment Share on other sites More sharing options...
Incommando Posted June 21, 2015 Share Posted June 21, 2015 Can't wait to get new gears so I can get 31's...I run 80 on the highway and wheel often with 32's and 3.55's is that with a stick or auto? My brother had a XJ with an auto and 3.55's with 32's and it was still peppy. Auto. Link to comment Share on other sites More sharing options...

Maybe we should think about bring ing it back. Fluid drive by Chrysler. The problem with this system however was drive train power loss, like about 40%. :eek: Link to comment Share on other sites More sharing options...

Three on the tree with a fluid clutch. Think his car was a 1949 Plymouth. My first car was a 53 Studebaker with a Borg Warner 3 speed automatic and a 232 V8 Edit: I see another old fart answered!
