Good To Know

Q: Does this post include the lanyard cap? A: No, this listing covers the D.E.S.S. post only, so the lanyard key is ordered separately. Confirm your existing cap matches the post before installation.

Q: Why replace the D.E.S.S. post? A: A worn post can fail to read the key and prevent the engine from starting. Replacing it restores proper key recognition on compatible models.

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