C6 X-Tracker SKF 33 spline hubs, also C5 hubs, both with ARP studs

[Blown353]

All sold 2/24

Putting a Mk60 ABS system on my car with the motorsports software and I need new hubs with the active (yellow wire) speed sensors.

I have the following available:

2x C6 ZR1 / C7 33 Spline SKF X-tracker hubs with no wheel speed sensor. These have ARP 1/2" studs installed and the stud heads are notched to clear a C6 e-brake mechanism (they're actually Mustang #100-7722 studs that already have the notch in the head right from ARP, and the stud holes in the hubs were reamed slightly larger from 0.490" to 0.532" on a milling machine to accommodate the slightly larger spline diameter of the 1/2 studs.)

These are brand new and unused. I received the hubs from MillerBuilt for my floater rear end setup, reamed the stud holes on a milling machine and installed the ARP studs, then put them back in the box.

Asking $425 shipped and insured for the pair

2x C5 SKF (non X-tracker) hubs with passive speed sensors and ARP 1/2" studs. These came with my ATS spindles and were ordered with the 1/2 ARP Studs. Since they're off ATS spindles one of the 3 hub holes has been drilled out for the stud on the ATS spindles and is no longer threaded. These would be a good spare set for your ATS spindles, but not good for anything else since that one hole has been drilled out. These have about 5000 miles on them. Bearings, studs and flanges are in great shape, a little surface rust in the center bores.

Asking $175 shipped and insured for the pair

Dumb question
Are these the same flange as the C6 fronts?

[Blown353]

The ZR1 / C7 HD hubs are the same flange size/bolt pattern to the spindle and wheel flange offset and register diameter are the same as the C6 front hubs, yes.

The bodies of the HD hubs are larger to accommodate the larger heavier duty bearings, but that isn't an issue for installing them in factory style spindles where the 3 bolts come in from the back side to hold the hub to the spindle. That larger body does pose problems for installations on ATS spindles however that have 2 bolts and 1 stud.

Well that rules me out since I've got the ats up front on my 67.

Yep, they need machining to fit on the ATS spindles. The earlier, lighter duty C5 hubs with the smaller bodies had enough clearance for a thin nut on the stud and only needed the threads drilled out of the lower hole of the hub body to fit on the ATS spindles to slip over the stud. The newer heavier duty X-tracker hubs with the larger bodies require additional machining to work with the ATS spindles since the OD of the thin hex nut is much too large and hits the larger X-tracker hub body.

I know Speedtech performs the hub mods for all new ATS spindles since they now ship with C7 hubs (which are all the larger body, heavier duty X-tracker hubs) but I don't know if they'll machine hubs that a customer ships in or what the cost would be.

I machined my new ZR1 hubs with the active style ABS sensors that I needed to work with ABS to fit on my ATS spindles, here's what's involved...

After that you use a reduced height and slightly reduced OD ARP 12 point nut to hold the lower hole of the hub onto the spindle, and install it through the access hole drilled through the wheel flange with a thinwall socket.

I read your hub modification thread. Impressive. Are you a machinist? I do some very minor stuff for myself. I have a small jet square column mill with auto down feed, tap capable and rotating head along with a rotary vice. Very handy in the shop
I re drilled the C6 regular hubs for mine to take 5X120mm bolt circle.
I'm 100% with you on balance holes. Definitely needed.

Not a machinist, but an engineer that likes to play in the shop whenever I have a chance. I mainly do part and tooling design, manufacturing engineering, occasional CNC programming, precision metrology, etc... but what I really like to do is go into the machine shop and make chips. I don't get to do it nearly as often as I'd like, as the machines are usually tied up doing work that actually makes the place money, LOL! My side jobs have to fit in whenever there's a bit of down time. Need to get some machines at home but don't really have the room for anything until I expand my shop.

Would you be open to a $300 offer on those rear hubs?

Sorry, I hadn't checked in here for a couple of weeks and even though I am subscribed with email notifications I didn't receive one about your post above.

I sent you a PM if you are still interested.



Sorry for the delayed response.

Bump for the ZR1 hubs.
