Dana 60 vs ford 9 inch

hey guys , im just finishing up a motor swap and i came across a ford 9 inch. I have a coil spring 44 up front and a ff 60 rear. Now the problems begin. The front is 5 lug and the back is 8 , and i dotn want to swap the outters to 8 lug up front because everything is brand new. Also my 60 is welded and the 9 inch is limited slip , with matching gears to the front 44. I can save myself a lot of money by putting in the 9 inch because i wont have to re-gear , and it comes with really nice rims. My question is , will the 9 inch hold up to my mildly built ford 302 and c-6 combo? If it helps , the 9 inch is out of the same 79 f-150 , and i plan on running either 39.5 tsls or iroks.

Go with 9 inch. It will be plenty strong for a 302 and after market is huge.

The nine inch is a strong axle but not as strong as a full floater 60. I would keep the 60. Either sell the stuff from the 44 or maybe you can get a spacer/adapter to convert the 44 over to 8 lug. You could have the 60 redrilled to match your 44.

Go with the 9". It came from the factory behind much heavier vehicles with engines bigger than 302s. It can be built to be as strong as a 60 down the road should you happen to break something. Not to mention they are light and you can shave the housing to have more clearance than your 44 very easily.

i'd slap some chromoly shafts in the 9" and it would be lighter, stronger, possibly more clearance if you shave it down, sounds like a winner to me

I'd keep the 60 unless you plan on selling the 60 and putting the money into the 9"

A lot! That is definetly NOT the cheapest way to do it! I'd like to see them do a junkyard 609 build like most of us would do, but Spidertrax pays more for the show than Billy-sue's junkyard would. All the basic ideas were there though.

I plan on (someday) building a 609 to get rid of my heavy sob ditch-digger 14 bolt. Not any time soon as I am currently too busy wheeling the wee out of it every chance I get.

Here's how I am going to do it.

-junkyard housing shaved, plated and trussed end to end (I dont have leaves)
-Strange low pinion nodular 3rd with 5.13s and Detroit
-WFO housing ends
-Stock GM 60 front spindles and wheel hubs (already sized for 35 spl shafts)
-35 spl Alloy USA shafts.
-Cheapest flanges I can find

A full float 609 with non-bling 80's Chevy truck brakes will weigh in around 300 lbs give or take. Semi float with small 5/6 lug brakes even lighter.

The 3rd will be the most expensive part, but I wrench for a living so I can save some money setting up the 3rd myself as opposed to buying one pre-assembled. Check Ebay, nascar teams sell 9" parts all the time!

I get angry watching that show. They do a lot for the scene and all that but sometimes I wonder why I watch a 30 minute infomercial for 3 minutes of tech

That set up would cost more than I am welling to put into a pile of junk that I plan on throwing in the mud and dragging over rocks.

what type of 60 do you have and what did you do to it. do you have the 30 spline axles and the small boar spindles or do you have the 30 spline axles with the big boar spindles to accept the 35 spline axle, if you have the big boar spindles then keep it and upgrade it. remember the 9'' is eather a 28 spline or 31 spline axles so unless you upgrade the 9'' to 35 spline what strength did you gain. your actually going down hill if you install the 9'' your going to a semi float axle. i am not saying they are weak ( the 9'' ) but you allready have the 60 in there and if your end goal is run 39 iroks then i would be worred more about the front 44 handling the 39's than the rear at this point, jason.

Pulled the 60 today and grinded off the old perches on the 9 inch. Should be ready to go. The 44 should be good , its pretty beefed up. Just have to wire the motor now ( yikes). Anyone have an opinion on 39.5 tsl's or the same size iroks? I need to order tires and im torn between the two. I drive around town on the street , and wheel mostly mud and trails. I also drive it on the beach every weekend. I really like the rok's , but i was told they wear fast. I cant really imagine them wearing faster than boggers or tsl's though.

if your looking for wear and tear then don't order a bias ply, stick w/ a radial swamper or something.
