Models: 2003 Chevrolet Corvette with Magnetic Selective Ride Control (RPO F55)
Magnetic Selective Ride Control (RPO F55) will be available on the Corvette for model year 2003.
Magnetic Selective 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. Vehicles are shipped from the factory 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 customer dissatisfaction with the vehicle’s ride quality.
In order to remove the stuffers, follow these steps:
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.
