hey was wondering at what hp/torque level are 31spline billet axels rated to? can a 35spline full spool be bought for the BW diff or does it stop at 31? i know lowey has run 8.90 with these axels so i know they can hold ALOT of power ect but wondering just how much what other work should be done to the diff? i will be running boxed lower arms and adjustable uppers with a full spool and 31spline axels also, how do the strange axels compare (hy-tuff and ss/st) to moser? there a little cheaper then moser but seem to still be very strong cheers Troy

A bit off topic but I was always told by blokes on here that boxed lower arms were only worth it for mild street applications and that once you moved into serious territory you were better off with stock arms. Not sure why, just what everyone seems to believe. Any ideas? I'm sure you could get a 35 spline spool made to suit.

that doesnt sound right there going to twist lik nothing else and break under serious torque/power being stock so you would want to weld material inbetween so they cant ill look into the 35spline spool for the BW but id say 31 will do me fine if i had the money tho, id go tubular lower arms, coilovers, adjustable uppers, tubs, 9", the works but i dont have a spare 4K lol

Check the link man, everything is listed there and if you know certain specs, it can calculate what type of axles you need. http://www.moserengineering.com/Pages/axletech.html

thanks for that mate seems 31spline will definitly be enough cheers Troy

If ya ever gonna go to all the effort with doing a nine inch. Look into using landcruiser/patrol diffs. Plenty of spare parts, plenty of aftermarket parts and they are superstrong from the get go... LSD's in them seem to work well too...

thanks for that Hingo, good info yeah 9" isnt needed as proven by lowey thats run 8.90 with 31spline mosers

The thing is though, 9" diffs are easily available to suit Commodore whereas Pootroll/Cruiser diffs more than likely aren't. I think you'll also find that the 9" has 10x the aftermarket support too.

has anyone had any good quotes on a pair of 31spline mosers and romac full spools? looking to do mine in the next couple weeks

moser axels at mcdonald bros are 695 a pair strange axels thru vpw range form $470 upto $620 for axels alone not sure if when u buy moser axels that you get bearings and studs aswel? not sure on the spool, think there around $350

i got quoted today. moser 31's $750 with out bearings and studs add approx 100 he said for them $475 for romac spool. will beat him down on them prices now. whats mcdonalds bros site?

http://www.mcdonaldbrosracing.com.au they do them for $695+post, made to order

QPAC were cheap.. ring them

whats QPAC Colin? waiting on a quote for the axles, spool is a fair bit cheaper than what u mentioned tho if any1 needs a spool then let me know by pm, there in stock and ready to go, i will be ordering prob 2moro or thurs cheers Troy

I got 28 spline billet axles from McD Bros $695, took 3 weeks from USA and they freighted them to my door for free (which was a surprise, as I was meant to pay) They don't have bearings or studs. I got 10 studs for $20 from Holden and bearings for $30pr from another source.

Anyone got some more info on this? Best prices, best brands to go with? and where best to get it from, for a pair of 31 spline billet's and full spool.

im organising some spools now so if you want 1 then let me know been guaranteed they will be the cheapest around already got 2 wantin them, there romac 31splin full spools for the BW diff as for axles, Mark Williams are prob the best you can buy, but Moser will do the job just fine which is what ill be getting let me know if your keen on a spool, still waiting on prices of the axles cheers Troy

sorry Troy its QPAAC ...qld performance axles and centres, i paid $595 for Moser 31 spline axles & $380 for a Romac full spool Col
