I had this diff in my CMC car after it was built by Texas Drivetrain Performance.
No issues at all. I replaced it with a diff that had 3.73s in it.
No leaks, no whine, 3 channel

Stock axles, backing plates for a 93-97 brake setup, ARP wheel studs.

I think I have one season on it. Well maintained with Redline 80-140.

If you aren't familiar with CMC, it had a whopping 230 RWHP run through it.

$750 takes it.

Located in the DFW area.

If it was only closer to WNY...my guess is shipping would be a bear.

Unless you could find someone who was travelling this way for the holidays ....

Educate me. 3 channel is for the LT1 cars, and 4 channel is needed for LS1 cars?

My '02 T/A streetcar howls, I think from an axle bearing needing attention. My racecar wants a T2R.

3 channel is for non traction control (TCS) equipped cars.
4 channel is for traction control equipped cars.
