i feel somewhat retarded asking...but...

can someone please explain the difference between a 4 channel rear and a 2 channel rear...and why a 4 channel doesnt have a ring reluctor for abs and tcs.

thanks

 

The 4 channel rear is the traction control rear. It has 2 reluctor rings. One on each side on the axles.

The other one is a 3 channel rear and is used in abs only cars. It has one reluctor ring on the differential.

 

from your description, can I assume my 01 Z-28 with the traction switch on the dash is a four channel system? Thanks.

 

what do the reluctor rings do? if i was to replace my rear, do i have to replace them?

 

The reluctor rings are just rings with teeth on them. The spin in close proximity to the sensors providing speed information to the abs and traction control computers.

If you want to retain abs or traction control you need them.

 

should i buy new rings...or can i reuse the old one?

 

If you get a 93-02 F-body rear they will be there already. If you have abs only make sure you get a rear from an abs only car. If you have traction control get a rear from a traction control car. If you have traction control it may be possible to use an abs only rear if you swap brake backing plates and axles. I'm not sure.

If you mean an aftermarket rear you need to talk to the company selling it.

 

no, im keeping my housing...replacing the differential...eaton or auburn (havent decided yet)...do they come with new ones...should i buy new ones...or can i reuse mine...

 

If you have traction control you don't need to do anything. If abs only I would get a new one.
