Post what rear axle in a f-250

I have a 1996 F-250 diesel and was wondering what rear axle is that. It looks bigger than a 60. Is it a sterling 10.25? What is a sterling 10.25 and how good are they in a smaller offroad jeep??

it is a 10.25. they are very strong. the only bad thing about them is gear selection is limited as are lockers. i believe up till the new superduties the only gearing yah can get is 3.55 4.10 and 4.56. the newer superduties actually have a bigger ring gear in the sterling rearends, 10.5 i believe and i think there are 4.3 gears available for this one also the 4.1 and the 3.55 not sure about the 4.56 though.

Sterling is a corporate Ford axle. It is the big brother to the 8.8.
Basicly, Ford told Dana to hump their fist, they would build their own HD axle.

As others have said, the only problem is limited aftermarket options. Genuine gear, and Yukon gear make R&P for them, up to 5.38 ratio...see:
http://www.ring-pinion.com/a-ford.html

They are hell for stout. Salsbury design, so you have to shim the carrier bearings, so not near as nice as side adjusters on a 9".
No end bearing on the Pinion, but big bearings and a huge pinion shaft, so not a problem. It's not a full truss, but the center casting does have some serious truss-like ribs. The 99+ trucks have rear disks...older ones BIG drums. F-350s have same rear, unless dualy, then it's a Dana-80.

Unconfirmed rumors:
Beware that newer trucks, (99+) with the 10.5" gear in same housing have different spline count on the axels. The differential case is the same however.

I've got an ARB airlocker in mine. It fit the older splines fine, but I had to turn the ring-gear mounting flange down by .15" to accept the speedometer sensor ring.

As a point of referance my 98 f-250 has the sterling 10.25 with disc brakes.

Hmmm I bet thats right come to think of it...is this the '250 light duty with the semi-float axle, and the meltdown body style?

its a great diff for Tow rigs, For a Jeep it just hangs down to far, you would be better off with a shaved 14 bolt

I have teh 10.25 under my 250 and love it, i swapped in 4:56 and this diff is great!

I have one in my trail rig...I love it, it's really fawkin' heavy but it's about the only thing I haven't busted yet. They don't hang down quite as low as a 14 bolt

I have been thinking about shaving mine...but I've come down on some rocks really hard with it a few time and it just laughs. I really don't want to shave it then fawk up the housing smashing it into rocks. But I did just get another complete 10.25" so I might try it.

Anyone know the width of a DRW 10.25 compared to the SRW??

I am thinking about using it in a custom rig with 44's, arb, and 5:13 gears. The price is right on it and I was wondering if it is worth using on not?

If your dead set on using 5.13 gears...it prob won't work. You could go 5.38's in the 10.25 but if your using a RC 60 front you'll have to stick with the 4.56's as they only go to 5.13's. If your going with a standard 60 front then It should work great.

Randy's R&P does list a 5.38 for the RC 60. I am worried that with 44's 4.56 won't be enough gear. Any opinions???
