2005-2013 C6 Shock Absorber Simulator Kit For F55 Suspension

Eliminate malfunction indicator light(MIL) and associated codes with our F55 Suspension Simulator Kit for your 2005-2013 Corvette.

By using our 2005-2013 F55 Suspension Simulator kit, you can then choose any shock absorber that suits you, and turn the MIL codes off, restoring the car to its original control. Kit consists of eight modules, two for each wheel location. Simple "Plug-And-Play" installation.

Active suspension was a great idea for the Corvette. But, when replacing leaking factory dampening shocks, you got "shocked" when you discovered that the cost of ONE factory shock could enable you to replace ALL FOUR shocks with the best aftermarket shocks! If you do this, however, the MIL light turns on and the car's top speed is limited to 80 MPH!

2003 Corvette RPO F55 Magnetic Selective Ride Control

On 2003 Corvettes equipped with F55 Magnetic Ride Control (50thAnniversayr Editions) we have had many customers complain about the stiffness of the ride and lack of dynamic stability.

Magnetic Ride Control works like this: When the vehicle is being driven, various sensors pick up data which is processed by a control module. Using pulse-width modulation, the control module varies an electromagnetic field in each damper, which affects the thickening of the magneto-rheological fluid, within a millisecond.          

When the ignition is turned OFF, the dampers offer very little damping. Corvettes are shipped from the factory in Bowling Green with the suspension snugged down until the jounce bumper contacts a temporary plastic stuffer in each damper.


The stuffers must be removed during new vehicle preparation. Failure to do so will result in your Corvette not handling correctly and the vehicle ride quality will suffer immensely.

In order to remove the stuffers, follow these steps:

1.     Lift the Corvette, allowing the wheels to hang free. This will extend the dampers.

2.     At the front, steer the wheel in the direction away from the side you’re working on.

3.     Reach up from below, behind the tire. At each wheel, compress the rubber dust boot.

      4.     Pull the yellow tab to remove the stuffer. Discard the stuffer.

*NOTE: After removing the stuffer, be sure to pull the dust boot down to cover the upper end of the damper tube in order to avoid damage to the suspension system.


The stuffers should not be reinserted for temporary transport, such as on a flatbed hauler. The stuffer is effective only if the suspension can be snugged down enough for the jounce bumper to contact the stuffer. This is generally NOT possible on a flatbed hauler.
