I am getting a 14 bolt and i am wondering how low i should go with the gearing. I drive a chevy truck with a 700r4. I would like to keep it some what street drivable but i do want he lower gear. I am planning on running 38.5 or 39.5 inch swampers. What do you guys think. Thanks

Ryan isn't the 700r4 an overdrive auto? if it is... get in the 5's <IMG SRC="smilies/biggrin.gif" border="0"> The Ranger's got 38's with 5.43's with overdrive, it pretty much kicks ass. I realize the v-8 doesn't need the lower gears to turn the tires down the highway... but it'll help on the trail. Which is the stupid reason we do what we do right? <IMG SRC="smilies/biggrin.gif" border="0">

Aaron do you know any body with parts for a dana 70. I have one with 513 but i dont have the brakes or the hubs and stuff. I also just landed a deal on a 14 bolt in good shape from a guy who will delivere it to me for $125. So if i cant find parts for the 70 i will build the 14. How was the rubicon the last time you went. I talk to andrea and she said it was a lot of fun. Wish i could have gone.

I could probably get my hands on the brake parts for you, cause eric put disc brakes on his d70. But that would only be drums, backing plates and brake parts. He put the rotors on the stock hubs. I've seen d70's on occasion at pick n pull... have you tried there yet?

aaron see what you can do. I can buy the hubs anmd stuff new. What did it cost him to do the disk brake conversion. This seventy is setup up really nicely and i would love to use it. Ryan

the disc conversion is actually really easy and probably more cost effective for you. You can press the wheel studs out of the hub assembly that holds the drum and put rotors on the hub assembley. He used 3/4 ton chevy rotors and 1/2 ton chevy calipers. Eric made a braket to weld to the housing to hold the caliper. But if you had a extra set of the chevy caliper hanging brakets from the front of a d44, you could just cut out the radius of the axle from the brackets and weld it in place.

who setup your gears? Did you do it yourself? Is it really that hard. I think what i might do is get gears for the 14 bolt and use it. I am palnning on buillding a toyota eventually so i will build up the seventy for that.

BTW there's 3 threads on how our con trip was <IMG SRC="smilies/biggrin.gif" border="0">

The gears, yeah i did my own. Installing them is easy, setting them up is hard. You absolutely must have access to a press, without that don't bother. Don't think you can just have a machine shop press the bearings on and off for you, cause you'll be back there 10 times, which will cost more than paying a gear shop. You also need a bearing puller, micrometer and dial indicator. All of the other tools can be improvised. The 14 bolt is a relatively convient axle to setup just like the ford 9".

Looks like you guys had fun. Maybe once i get my gears we could hook up and you could show whats up with doing them. Right now i am just going to weld up the spyders. If that doesnt work i will buy a spool. Ryan

I used to run a 700R4 and would say get 5.13.
If this is in a tow rig you really should not tow in overdrive especially if your rig has a torquey engine and can pull the weight in overdrive. I don't care what your transbuilder says. When they say you can tow on the flats in overdrive they are thinking you pull a couple jetskis or dirtbikes not another rig, trailer, camping gear, spares, tools etc. 4.88's are probably a bit better for towing out of overdrive with 4.56's usable if you make alot of torque. Even with 5.13's you are equivalent to a 3.591 in OD which is about perfect when not towing. With the 4.56 and 4.88's you will be a bit sluggish in OD unless you have a built motor.
