Hey guys, I'm getting ready for the axle swaps on my 94 F150 and am going to go SAS D60 ARB front and was wondering what everybody here thinks for the rear? D60 35 spline FF ARB w/ 1350's and disc or get a 10.25 FF and ARB/disc? I'm going to run 37"s on it, so not too terribly huge on the tires. I was going to go with the 8 lug too. I offroad some, (my Jeep gets the most work out here) tow 5400 lbs, have abut 400 hp and plan on a 200 hp nitrous addition soon. I have to be able to slog through some deep, unplowed snow in the winter for about ten miles each way when I go up in the mountains, so the clearance issue is somewhat important here too. What do you all think? Thanks!
well the sterling is stronger no doubt. but two drawbacks about the sterling....you can't disc a sterling with a lot of research and fabbing and the sterling hangs down a lil lower than the 60
if i was you i would do the 60 since it is pletny strong and won't be as much of a clearance issue....esp if you don't plan to wheel it!
I would go with the Sterling 10.50" with factory disc brakes from a '99-up F250/350 pickup. The drawback of that setup is the wheel bolt pattern is different on the '99-up trucks (8x170mm -vs- 8x6.5"), but you could also go with '01-up front hubs and rotors, since those trucks also have Dana 60 front axles. Might have to use the whole knuckle/spindle/hub/caliper assembly, not sure. The 10.50 axle is also a much stronger axle (rated 9750 lbs GAWR in SRW form (same as dually) -vs- 6250 lbs GAWR for the 10.25 SRW).
Personally, I would just get rid of the F150 and buy an F350 instead, it already has the axles you want, and everything else about the truck is heavier duty as well, except the body. Stick that motor in an F350 and you'd be done....

Any idea what the D60 with the ff, 35 spline and 1350's might be for GAWR? I've been lead to believe that these beefed up 60's are nearly as strong as the 10.25, but theres a considerabe difference in those r/p's there,so can they keep up with the extra goodies?
I'm really inclined to lean toward the D60 for simplicity on the brake/wheel issue and small amount of clearance vs. the 10.5 set up. So I would have to say I's still go for either 10.25 or the Beefed 60, humm...
Also, I deceided to opt for the Atlas instead of the NP205 and a set of HighAngle's Drivelines for the project too, any take on these things too guys?

I might be wrong here but I've done a fair amount of research on the Atlas cases and it seems to me like they're not built to handle serious horsepower, but rather to be a tough crawler. If it were me I'd rather do a 205 and if you need the lower gear range do a doubler. It'll cost you far less money than the Atlas and be better suited for the engine you're building.
The one thing I don't like about the Sterling is your options are very limited. If you go with a 60 there are tons of aftermarket parts for it.
I think I agree with what Ivan said on the Atlas, I have also heard they are not built for power. I think the max power is 300 or so???? Correct me if I am wrong.
You can't beat the NP 205, it is pretty bullet proof. You can run an NP205/203 doubler for less money than you could pick up an atlas and really crawl if you wanted to. Like ivan already said.
I think if it was me doing the rear axle swap I'd go with the dana 60, it'll be pretty strong with a few minor upgrades. Also you can pick up these axles for cheap.
205's are relatively cheap and if you're interested in low gearing check the thread here about the 205/203 doubler. You can do that, all parts included, for about $700.
Stay away from S/D axles, stay FAR away...
Front end has unit bearing hubs, rear has smaller wheel bearings and closer spacing that a 10.25, neither are big tire friendly.
They key thing here is that he has the larger diameter, 35 spline axles. Makes a big difference in a Dana 60. That being the case, I'd keep the Dana 60 over the 10.25.
Thanks for all the responses guys, I'm checking into some sources for some 205's tomorrow, I found about 5 souces for them. Who is it again that makes the twin stick kit for the NP205?
I went to Advance Adapter's site to do some more researce on the Atlas, and I couldent find any information on their site regarding the HP/TQ handling capabilities, only some info on their 32 spline front output making their unit considerably stronger than the other Atlas? Any links with info on the strength limitations of these Atlas Cases? I'm only asking because the dang thing wieghs nearly half as much s the 205.
