8 lug, 35 spline 9" shafts

[Cody]

anyone know where to get 8 lug 9" shafts? I'm thinking of going up to 35 spline and if I get a front 60 then I need to either convert the 60 to 5 lug or convert the 9 to 8 lug.

Also, I have the big bearing 9" housing and from what I can tell all I need is the 35 spline shafts (and maybe a different bearing?) and the 35 spline spool. My carrier should work.

Is this accurate?

I would guess Moser or Currie would be the place to get them. I beleive all the rest of your info is correct.

I don't think they make 8 lug semi-float shafts for a 9"?

I know some people use 14 bolt outers on 9" housings to upgrade to fullfloat 8 lug + 35 spline shafts.

I know Bob Roggy on PBB did it to his semi float 60 a few years ago.

Might look over there.

What about redrilling your shafts?

 

[Cody]

I'm pretty sure 9's never came 8 lug so they would have to be custom drilled. Is it possible to just re-drill a 5x5.5 patter to 8 lug? I know where to get the 35 spline stuff, maybe I should just holler at them and see if they know how to get it to 8 lug.

I think if you convert the 60 to 5 lug you have to redo all the brakes and stuff to 1/2 ton equipment which becomes expensive...thoughts?

yeah Roggy drilled his semi float 60 shafts to 8 lug from a 5 on 5.5

I would agree that it would cost more to do the front.

post what you find out cause I am considering going this same route but that has been my concern...I was thinking cheap for now and just doing wheel adapters...

A 35 spline 9" shaft will be a custom item so redrilling is not an issue. You just need to order what you want. The best shafts are made by Summers Bothers, Mark Williams, Strange, Ect. Summers has been involved in offroad markets more than the others. Strange and MW don't seem to care much about offroad customers but their highend stuff is still good stuff. If you dont care about having shafts made with the best materials, correct heat treat and proper profile give Moser a call. The axle will cost you plenty you will need a new third member, what you call a bigbearing housing has large wheel bearings but the third does not have the bearings that can support the big shafts, they are aftermarket only.

last I heard, Randys Ring&Pinion was offering a carrier bearing that would work with the stock carrier and allow for 35 spline shafts...but it wouldn't be a bad idea(besides cost) to get an upgraded third member...by running the special bearings you are gonna end up with some small bearings...

I had not heard of that but it sounds like a really bad idea. I believe that the weak link in a 31 spline stock non nodular third membered 9" is the center section. What advantage is there to 35 spline shafts in a stock third? If it was me I would spend the money on a nodular third and wait on the shafts. I'll take a nodular third and 31 splines over a stock third and 35 splines any day.

I agree 100%

Yep, very bad idea to do 35 spline in anything but a 3.25" carrier bearing drop in. People have done it, but you end up with small diameter bearings and/or thin bearing lands on the carrier. Asking for breakage.

Any axle maker should be able to do an 8 lug shaft for you. I suggest Currie because the waranty the shaft if it breaks anywhere, the others IIRC, only waranty the shaft if it breaks inside the bearing. You are SOL if you bend or break the flange. Almost all except for moser, use Foote axle blanks to build from, so they are more or less the same.

Check summit/jegs, a 3.25 drop in runs about $300. If you want real beef, do the drop in, add a 35 spline pinion (r/p set), with a hd pinion support and a billet yoke!!

I've found some nodular (n) cases on ebay for failry cheap--and I found a Strange case for under 200 brand new. If I were to buy the Strange case (3.25), what else would I need to do the 35 spline.
35 sp spool
shafts
different carrier/pinion stuff?

Not all nodulars are 3.25. You can use your pinion support, but I would up grade. You can use you gears too. (can upgrade to 35 spline pinion set). Either detroit or spool, if you are going spool, just do 40 splines, same prices, but no detroit option. OR you can do 33 spline spool/mini spool with the stuff you already have.....

I beat the crap out of my 35 spliners, but would go 40 if I was running a spool.

 

[Cody]

Is there a price difference to go 40 spline?

Can you give me a basic 35/40 spline shopping list? I'm already going to be getting gears. Would the Strange case be alot stronger than an 'n' case? This is the case I'm thinking of getting...

what else would I need to set this up strong for 35/40 spline?

Thanks oh guru of all that is 9 inches ;D

Its about $100 more for 40 spline shafts from Moser.($295 for 35 $395 for 40)..I am eventually going to do 40 spline just like Marc said, everything else is the same cost. That is the same case I was looking at getting. IMO it should work fine...but what do I know

 

[Milner]

Thats the case I have.
You need the case (drop in), carrier/pinion bearings, diff/spool, pinion support (get the nascar one). You can go with the 35 spline pinion gearset, and 40 spline shafts, not sure $$ but should not be much more than 35spline axles and regular gear set. Make sure you order your axles with the bearings and retainers installed, makes things easier (they will need to know your retainer patern/what the housing is out of).

Just looking at the moser stuff from summit, looks like the shafts are $100 more but the rest is the same $$.

IIRC Jegs had a kit that included the droping, support, and bearings for a little over $300.

Currie has thier own line now, try 9plus, not sure what the www is, but its not 9plus.com...opps sorry if you tried that.
www.musclemotorparts.com has some stuff some times too.
Also check out circle track catalogs, or go look through a Circle Track mag for sales.

9" stuff is everywhere and priced competitively.

feel free to give me a call 949-5348

Find a 14 bolt and butcher it for the ends, I want to do something similar with a 9" for a later project. Go with a nodular drop in, I see so many stock 9" housings with the pinion support ripped out of them lately. I think the Six States in Orem may have Strange cases in stock?

By the way congrats on the spread in 4wheel!

 

[Cody]

thanks Andy. Are the strange cases worth the extra denero vs. the 'n' cases?

I really shouldn't be talking about this because I can afford the front 60--maybe, but then I need new rims, rear shafts etc etc. It's more expensive the more I think about it....

 

[Andy]

Yeah, the Strange drop in is worth the money, but if Randy's has a bearing that will work in your stock drop in you might want to look into it. I have yet to see a Strange case break. As for the money part, tell me about it...you just have to ask your self if it's worth the peace of mind???
