Rear end which one?
Went to look at a few today from local junk yards. Looking at the ford explorer rear ends and I did research all the topics on here about them. One question I have that I did not see is which one is better for overall daily driving? 3.42, 3.73, or 4.10? I am thinking 3.73 but what do the experts on here think?

Re: Rear end which one?
What are you wanting to do with it? Is it strictly for fun or is it going to see some regular driving? Also, what motor?

Re: Rear end which one?
Yes, should have given more info. Looking at a daily cruiser, regular driving. I have a fresh stock 305 with 700R trans set up right now to go in this truck. Something good on highway driving also.

Re: Rear end which one?
If you have an overdrive transmission, I'd stick with the 3.73 or 4.10, you'll be much more pleased, especially if you have a 6 cylinder engine. A 3.55 or 3.42 rearend would be good with an original 3 or 4 speed.
I've had 5 overdrive equipped vehicles with 3.42 or 3.55 gears. They all could've used a little more gearing when towing or hauling. Anyway, that's my $.02 worth. |

Re: Rear end which one?
my 97 camaro ss has a 396 LT1 that makes about 450rwhp, mated to a built 4l60e. i have 3:42 gears in the rear end. get about 20 mpg's and will still set you back when you get on it.
if i had to do it over again i'd go with 3:73 gears for a little extra kick in the pants |

Re: Rear end which one?
Thanks everyone. Looks like I will be going with the 3.73 rear as this is the one most parts places have. I did not want to say "junk yard" as we all know one mans junk is another mans treasure.

Re: Rear end which one?
Just in case, when you're looking at rear ends make sure it has a tag like this...the 3L73 is the limited slip w/ 3.73 gears. Good luck

Re: Rear end which one?
Gonna ask the same question here- is there a GM 5 lug rotor that will fit the Explorer rear (if I redrill the axles), or can I use GM 12 bolt axle shafts in the Explorer rear?

Re: Rear end which one?
To my understanding yes. I just ordered a mustang 2 kit from southern rods and selected the GM 5x4.75 lug rotors but was also told these are drilled for the Ford 5x4.5 as well. Should get the kit in a few days and will let you know what I find out. At least that is what they told me via email.

Oooppsss. Mis-read that. Not sure for the rotors on the rears. Was thinking front end.

Re: Rear end which one?
If you're wanting axle shafts with a GM bolt pattern, I wouldn't even bother re-drilling the Explorer shafts. Call a company like Mitchell Differential or Dutchman and have a set made. They may even have them in stock, considering it's a common swap.
http://www.dutchmanaxles.com/product...le-shafts.html http://mitchelldifferential.com/custom-axles/ If you're going for discs on the rear, a S10 or Camero setup is what to look for. You may have to modify your axle flange though. |

Isn't the Exploder rear end offset?

Re: Rear end which one?
I used a 1976 Camaro differential which according to the code book and our count of the gears tells us that it is a 2.56 ratio which is fine with me. it gives my 350 transmission a higher 3rd gear. Almost like overdrive. The only thing I can never do with this differential is use a 700 transmission. I am more into fuel economy and do not plan on drag racing it.

Re: Rear end which one?
Here is a damn handy gear ratio calculator for various transmissions, axle ratios, and different tire sizes. It spits out various engine RPM's at 3 different speeds that you can change.

Re: Rear end which one?
Just picked up the rear today. Here is what the tag says:
S613C. R 3L73. 88. 7402 From this I do know it is a 95-01 explorer rear end with 3.73 gears and limited slip. Do these numbers tell me anything else? Again, I was able to get this for FREE. Will have to put new rotors and brakes but everything else is great.

Re: Rear end which one?
You just made my day. I'm getting close to paint on my 57. Hope to finish around Memorial Day. I installed a 3.27 posi Camaro disc rear, with a 96 LT1/4L60E. I will be very happy with that kind of mileage! Jason

Meanwhile, mine likely has the 350/TH350/3.73 combo, so 65mph is tight enough.
