Are 4.10s enough for 36s with 360/auto

Will 4.10s be enough gearing for 36" tires, with a 360 engine and auto-tranny drivetrain? I do mostly mud and sand, but want to be effective at Tellico, Uwharrie, and the like.

I'd be running D44 axles with a front Detroit and rearl Spool

Nothing to add to this... just curious if you're starting to build up your YJ or what?

I would say YES. I run 4.10s and 36 with the t-18 manual. With the 360, it will put out enough power to spin those puppies. And being an auto, your crawl ratio won't be too much of a factor over rocks.

Re: Are 4.10s enough for 36s with 360/auto

I would also say yes. I think that with 4.10's you will be just about right for everything. With an auto you are going to have the added crawl of a Converter, and with a 360 you are going to have no trouble spinning 36's. And on top of that you are going to have a very streetable jeep that will cruse really well at highway speed.
What kind of Transmission are you going to be using. I would assume that it is probably NOT an overdrive. If that is correct I think you have selected the perfect ratio.
But if for some reason you are using a trannie with an overdrive, I would go with a set of 4.56's or 4.88s.
Like I said though with a final drive of 1:1 4.10s and 36s are beautiful.

I'm running 4.10's with 39's. There are people out west that think I'm nuts, but on this side if the woods we need tire speed. If you decide that you need more gearing do it with a T'case set of gears..
go for it...

I have 4.10's and 33's and it is too low for highway for me. Offroad it is fine. I hope to go to 35's or 36's to help with the highway and clearance. BTW, I have a 360/TH400.

Re: Are 4.10s enough for 36s with 360/auto

I have a TF727 transmission installed, along with an NP-208 x-case. So far there are no aftermarket gears (or anything, really) for the NP-208. I've had the axles, gears, and lockers for a while, but kept thinking I should go for 4.56s with this size tire. I should be getting rid of my Samurai this month, either someone is buying it from me, or I'm trading it to get my axles built. They're D44s from an '86 GW, to which I'm adding the front Detroit and rear Spool. I don't know how streetable that will make it [img]images/graemlins/laugh.gif[/img] There is a junkyard nearby with a running 360 for $350 (with all accesories). It's still in a GW, so if it shows good oil-pressure when they crank it up for me, I'll be getting it next month.
Not exactly building the YJ just yet, so much as getting everything ready to install.

I have 4.56's with a 3 speed auto (999) and 35" tires. 4.10s would be better if you plan on driving it on the street/highway.. mine goes *OK* on the highway.. but wouldn't really want to run long distances with that setup (4.56's and no o/d)... although - I'll be goin to 37's soon.. so that will help a little.
