  • Q:

    My 2005 Cadillac CTS has the Fe 3 suspension the OE part # is 540147 A/C Delco. Will the rear gas shock by KBY be compatible. The OE suspension has a normal and sport adjustment will this gas shock work without showing a "Service Vehicle Soon" light?

      Happy to help with your question Frankemm! This KYB Shock shows to be an exact fit to your specifications. The Service Vehicle Soon light may come on due to your shocks being worn out or it could be that it needs to be reset. Some are designed to come on at certain mileage meaning maintenance is necessary. I suggest speaking with a certified mechanic for diagnosis on that light.
