How to Identify Your 2017 Corvette's Suspension Type

Before ordering parts, determine which suspension package your Corvette has. Check the RPO code list in the glovebox or look up your VIN online. Common codes:

• FE1: Standard suspension
• FE3: Z51 performance suspension (stiffer springs, larger sway bars)
• FE4: Magnetic Ride Control (available on Stingray, standard on Z06)
• Z07: Z06 with Z07 package (specific springs and bars)

Also note if your car has the optional performance traction management (PTM) which may affect sensors.

Tips for Buying 2017 Corvette Rear Suspension Parts

• Always verify your VIN with the retailer to ensure compatibility, especially for magnetic ride vs. non-magnetic ride.
• Consider replacing bushings and hardware when replacing control arms. Many OEM suppliers offer bushing kits (e.g., Powerflex polyurethane bushings for C7).
• For alignment after suspension work, you will need a shop that can adjust the factory toe links; aftermarket adjustable camber arms may be required for aggressive lowering.
• If your car has magnetic ride, replacing shocks with conventional units can cause error codes and poor handling. Either replace with OEM, or use a magnetic ride delete kit (like the one from GM Motorsports) for coilover conversion.
• OEM parts are often available through Chevrolet dealerships or online GM parts retailers. Aftermarket parts can be found through specialty Corvette suppliers like Zip Corvette, Eckler's, or Summit Racing.

Final Recommendation

For most owners, replacing worn components with OEM spec parts from AC Delco or Dorman ensures a direct fit and reliable performance. If you are tracking the car, consider upgrading to an adjustable aftermarket sway bar set and camber arms to dial in handling. Always prioritize safety and proper torque specifications. When in doubt, consult a certified Corvette technician or refer to the factory service manual for the 2017 Corvette.
