anyone have any hands on with a 9 inch in front? and is it possible to build your own 9" front? and i have searched with no luck.

lots of peeps do it- 9/44's 9/60's, search musta been kinda week- Badlands can build you one and they are close

I have a front 9 inch with 79 Bronco Dana 44 outers. Bought the housing from Currie and did the rest myself.

A buddy and I are building one entirely from scratch this summer. He has built a few before and they turn out really nice for cheap. You then just order the 3rd member from Currie or such and you have a stout axle for really cheap. So yes it can be done.

I am planing to put a 9/60 in my wrangler this fall and was wondering if the high pinion 3rd's are giving any one any problems? I know that the rear oil passages are routed differantly and the ring gear is that of a 8.8 but does driving at high speeds cause any kind of problems?

This will be going in my DD wrangler and will have 37's or 38's so I am afraid of this burning up pinion bearings. also if there is a problem with the high 9 than I will just run the stock 9 third. Also I know that I could easly figure tis out my self with a little parts search but.... which is cheaper, ordering the axle hole ready to go or to buy a housing and buld it with a stock third. I can build the axle my self so no labor.

thanks

i will be building custom 9" axles front and rear someday.
spidertrax housings
true hi-9 35 spline 3rd members with arb's
spidertrax knuckles/bearings
custom shafts/ctm's

so, to answer your question, it can be done. lots of companies make components for them...spidertrax and sunray engineering are the two i've looked at quite a bit.

This is the set up I am going with... I don't trust anything that comes out of Curries door... Your better off doing it yourself if you are able...

I've got a Currie 9" LP front and no issues. I've also got the Warn hubs so highway speeds are also not a concern since none of the wearable stuff is spinning.

Pretty damned happy with the whole setup, too. I didn't build mine, it was complete from Currie so I can't answer for the "build it on the cheap" question.

how much you look at for a empty bare housing setup? No C's or anything.

Spidertrax is 399.00. Hands down the best.

no shit? Thats under what i was expecting... I just wouldnt look forward to having some custom shafts made.

If you do end up building a 9" front, don't go to Currie...

Hit up Dimond Axle (a vendor HERE), they can hook you up with a crazy nice 9" housing with 60 or Toy outers

the Hi-9's are tough, going on my thrid comp season, running strong/no issues

I have a Currie HP in the rear. I wanted a high pinion and at the time, that was the only "9" available. I got Sunray to build it. Now that TrueHi9 is going, I plan to build a 9 for the front, move the Currie 3rd there, and get a TrueHi9 for the rear :) I will probably use SpriderTrax parts for the front. That said, I have several highway miles on the SunCurrie with no issues.

sounds a good plan- the Currie unit was tits when it came out in the right application- it should live pretty well in the front

I thought so :D And this is one reason I wanted a 9" - modularity. Easy to change gears, can buy a spare 3rd........

Just to clarify for ya the Currie HP9 uses an 8.8 ring gear. The Hi9 / truehi9 uses 9 inch gears.

In the fourth pic down or first "big" picture is the difference between the two. 1st gear of the 4 being 8.8 size, 3rd gear over being 9 inch size of similar ratio.

Third on the diamond housings....these are mine being built... I dont think that these, with a true hi-9 3rd could be beaten.

Now THAT is some tubing. OOOOF :D

I am in the process of building a Spidertrax 9 (heavy housing gives 3/8" tube) w/ truehi9, 35 spline ARB, sSpidertrax "Ultimate 60" knuckles w/ 450 unibearings and unknown axles (leaning toward Alloys w/ Longfields). IMO this, or a variation on it, is the slickest axle setup out there right now.

My wife has a truehi9 in the back of her YJ w/ 40" MTR's in it with no problems after a season. FWIW, she has cracked her Ford 9" housing in several places, even with a substantial truss on it...the aftermarket (Spidertrax or Diamond) housings are definitely worth the $$$.

is there a reason for using aftermarket 60 knuckles or could a guy use stock 60 or 44 knuckles. thanks for all the great info on this thread. also how wide can you go without going to wide

yes...lighter, stronger, tighter turning radius

heres the combo i've got stock 2005 4.0, stock 6 speed, 231 crawl box flipped dana 300,and now i'm going to add the 9" front and rear. my question is what size tire will i be able to run and my setup hold up. i am stretching 3" in front and 8" in rear so clearance should be fine. i don't mind breaking stuff but i don't want to break everytime i go out.
thanks

THe weak point will be your rear end (assuming it is a 44?) or the NSG370 six speed. THe front 9 should handle 40's given that the HP 3rd member is truehi9, not currie.

i'm going to build 9" for the rear at the same time so they will both be 9" s

IN that case, w/ truehi9's and aftermarket housings, I would think 40's no problem, maybe bigger.

I don't really know enough about the NSG370 to know how well it will do, but it isn't on the hi torque end of the setup, so shouldn't have too much stress on it.

I run the 609 that Sunray Engineering builds, LT1 with 42 TSL's No problems at all. I also have there rear 35 spline too. They build some nice axles and will build just about anything custom you can think of. Take a look at the shaved 1550 hex housing. http://www.sunrayengineering.com/
