Are Corvette C5/C6 and C7 front hubs interchangeable?

[stab6902]

Hello all,

Can anyone confirm that C5/C6 front hubs are interchangeable dimensionally with front C7 hubs?

I know that C5 and C6 front hubs are interchangeable from 1997-2008. In 2009 they changed the ABS tone wheel/connector, but otherwise they stayed the same. I've read from one source (http://www.vettemod.com/forum/showthread.php?t=10699) that the C7 front hubs are dimensionally identical to the C5/C6 hubs. The only difference between the C5/C6 and C7 design is the wheel speed sensor setup.

Here's why it matters:

• The C7 OEM quality hubs are way cheaper: C5/early C6 Timken front hubs: $126.79 C6 ZR1 heavy duty Timken hubs: $235.79 C7 Timken hubs: $75.79
• The C7 hubs supposedly have the bigger HD ZR1 style bearings in them
• The C7 hubs don't have the built in wheel speed sensor/wiring (better for our old non-ABS cars)

If the C7 hubs really are dimensionally the same as C5/C6 hubs, sounds like it's a no-brainer to run them in our C5/C6 style pro-touring spindles.
