Easy question for those in the know.

Are Speed Master Traction Drive System diffs good?

I clicked on their website and i think it might be linked to procomp, which im pretty sure are crap. Plus a mate told me to stay away from Sydney Speed Supplies.

Im looking at a 9 inch.

Whats your opinion?

If they are crap i'll go to Diff Technics, they are about $700 dearer.

The paperwork from Speed Master gives me a few choices i can make, they are-

A- 3rd member centre- Thru bolt alloy 3.250 or standard

B- Pinion support- daytona, super daytona, oversize, extended.

C- yoke- 1310 or 1350

D- mini spool- 28 or 31 spline

E- full spool- 28 or 31 spline

F- Torque worm- 28, 31 or 35 spline

G- gear set- 3.25, 3.5, 3.7, 3.89 or 4.11.

and in small writing it says all gear sets are 8620.

I was told the thru bolt alloy3.250 was really good, and get the super daytona pinion support, 1310 yoke, and 3.89 ratio. But i dont know the whole torque worm stuff. I just wanted a Tru Trac.

definatly procomp / sydney speed supplies & numerus ebay sellers, stay right away its all junk its all copied and its not made of what they say it is , i bought one of there torque worm lsd it looks like its was made in a shed with a grinder all internal gears have grinder marks , its just sitting on the shelf and will never be used, also the hex allen key bolts that hold it all together are not hardened they striped the centre out when i had it check out by a diif shop (Driveline Industries, Carrum Downs VIC 03 9785 1433), total junk and waist of my money, i will never buy anything cheap again, same old story you only get what you pay for.

Thanks Carmro. I rang the fella earlier today and asked him the brands used, and he told me he makes them himself. That sent alarm bells for me straight away. I didn't want to pay $4,500 for a diff that was a no name diff. And now reading your comment, that confirmed it for me.
So far I'm looking at Diff Technics now, but will call a few other places like Qpaac in the morning.

Yeh the bloke that was organising my diff gave me a few details and didnt mention SSS, but when i googled SpeedMaster a link came up to procomp and SSS. So wasnt sure if SpeedMaster were a good brand they were selling through a few places or what. The number i was givin wasnt SSS, it went straight to the diff builder which is contracted by SSS. But as soon as he mentioned no name parts that he built i didnt wanna go there.
Im on the blower now to a few diff builders and should have someone organised to do it by this arvo.

Also it's cheaper to buy the whole centre assembled (not paying tax on each bit or assembly), make sure if you go through Summit or similar that you use econo freight or you will loose the savings.

Yeh I was thinking bout them, but it's a 7-7.5hr drive from here, whereas Sydney is 5-5.5hrs. If I was living up there already I would go to altra 9.

Glad to hear shan620 that we helped another person to not get ripped off by these copy cat company's that are quick to take our money but when there's a problem your history, ive been caught a few times now by them and it will never happen again, it's all inferior made junk made to look like the good name product, and I don't care what anyone says, Sydney speed supplies, procomp electronics, speed marster, and all the other names they trade under, not to mention all there eBay name's they trade under, at racing world, Sydney speed supplies, muscle car hq, don't have and never will have a good name, ask any one that know's of them in the car world and you will be amazed to find how many bad reports you will get, it's happening so much more today with so many items being made by cheaper labour countries we really need to research before we just hand the cash over, this is just one company, sorry to go on and on but the mor people that are aware to this the better our cars are, as for you diff why don't you get it freighted its cheaper than driving that way you can use any one Australia wide.

I'd prefer to drop the car to the diff builder, that way I know everything is spot on and all brackets etc are right.

Yeh he's a good bloke to deal with, he calls me every 2 or 3 days with reports on the progress that's been done. I pick the car up off him around 15-16th January, so I'll ask him about speed master. Lol

sounds like you found a good shop to deal with, post some pics of work being done if you can be good to see, we need to try and rub these bad business' that copy products ect out of our hobby, all they do is take our money with lies.
