Good To Know

Q: Will this work on my 1999 GTX LTD 951? A: The listing covers the 1998 and 1999 GTX LTD 951, so check your model year and serial number before ordering. Comparing it to your existing part is the surest way to confirm the match.

Q: Is the setting critical once it is installed? A: Yes, the cover screw position controls when the RAVE valve opens, so set it per your service manual. Recheck the setting after the first ride to confirm it has not moved.
