Specs At A Glance

Good To Know

Q: How often should a carbon ring be replaced? A: It is commonly serviced whenever the seal assembly is opened or when wear, grooving, or water intrusion is found at the driveshaft seal. Checking it during routine driveline maintenance helps avoid unexpected leaks.

Q: Does this ring replace the OEM part directly? A: It is made to cross-reference OEM part number 272000770, so it fits the same seal position on compatible models. Always verify your model and serial number before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
