Corvette C7 Z06 Original **Chassis **Shock Absorbers Leaf Springs

stocking the original “chassis” components for the C7 Z06 requires careful attention to the factory suspension codes. Most Z06 models utilize the FE6 (Standard) or FE7 (Z07 Performance Package) configurations, both of which center around the Magnetic Selective Ride Control system.

1. Original MagneRide Shock Absorbers

The C7 Z06 shocks are high-tech dampers filled with magnetorheological fluid. For 2026 inventory, it is important to note that GM has consolidated many older part numbers into the “84xxxxxx” series for better software compatibility with the MagneRide 2.0 updates.

• Identification Tip: Authentic factory shocks will often have a four-letter alpha code on the label (e.g., ABZU, ABVH, or ADBR). Matching these codes ensures the damping curve matches the car’s original ECU calibration.

2. Transverse Composite Leaf Springs

The C7 Z06 uses a unique single-leaf transverse spring made of fiber-reinforced plastic (FRP). These are significantly stiffer than the base Stingray springs to handle the 650 hp output.

• Front Leaf Spring (FE6/FE7): #22982323

  • This is the standard high-performance front spring for all Z06 and Grand Sport models

• Rear Leaf Spring (FE6 – Manual Trans): #23344290

  • Specific to manual transmission Z06/GS cars; it balances the weight distribution of the 7-speed gearbox.

• Rear Leaf Spring (FE7 – Z07 Package): #22200944

   

  • The stiffest factory spring available, designed specifically for the Z07 track package to minimize body roll under high G-loads.

3. Technical Inspection for Showroom Quality

To list these as “Top Condition” for your luxury clients, verify the following:

1. Shock Leaks: MagneRide shocks can “weep” slightly (a thin film of oil is normal per GM), but any active dripping or “caking” of dirt at the base indicates a failed seal.

2. Spring Delamination: Inspect the edges of the leaf springs. If you see “splintering” or the layers of the composite separating, the spring is structurally compromised and unsafe for resale.

3. Electrical Connectors: The small pins at the top of the shock (under the plastic cap) are very fragile. Ensure they are not bent, as this will trigger a “Service Suspension” dash light.
