Found these today in my 2010.
Seems this packing material was not removed when the car was prepped 5 years ago. I believe these ‘pucks’ are so the magnetic suspension doesn’t bottom out in transit.

Wow! How many miles/

ChevyDave

yes they are. Was yours shipped overseas?????????????????? (i ask because you spell center as.... centre.. sounds British)

i remember researching this about 3 years ago , it was found back then on older c5. i cant remember the last year they used them, but i sure thought it was before 2010.
i think they are referred to as Shock Stuffers

for a fyi.. here is the info (i think it has the tsb for prior to 2005)..

Info - New Vehicle Preparation for Magnetic Selective Ride Control #02-03-11-002A - (08/18/2003)
New Vehicle Preparation for Magnetic Selective Ride Control
2003-2004 Chevrolet Corvette
with Magnetic Selective Ride Control (RPO F55)
This bulletin is being revised to add the 2004 model year. Please discard Corporate Bulletin Number 02-03-11-002 (Section 03 - Suspension).
Magnetic Selective Ride Control (RPO F55) will be available on the Corvette for model years 2003 and 2004.
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.
Important
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:
1. Lift the vehicle, 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.

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

Talon90 addressed frequent questions about these in the first few C6 years. Here's what he posted in July 2008:



I was under the impression that they did not even use these on the C6's and I've never seen pics of them on a C6 until now. Pretty interesting, especially on a 2010.

I'm saving this thread in bookmarks, OP please don't delete or move your pics. TIA

Bought from the first owner in western Alberta three months ago with about 14k kilometers (8.4k miles), drove 4k km (2.4k miles) back to Quebec, another 1k since.
Certainly more travel in the suspension now.

You have me curious now I may check mine but I figure after almost 9 years and 127+k miles they would be gone by now if they were there

I searched "selective ride rough "and found this thread. I just checked my 2003 50th anniv. and they are still there...DOH! I bought it with roughly 5k miles on it and it now has 17k...ouch!

When I bought my 50th anniv vert the shock stuffers were still in. I drove home on the interstate and was bounced around pretty good. Then I got word of the shipping stuffers.
I jacked each corner and removed the stuffers then hand delivered them to the dealer. He had no idea what they were so I gladly pointed it out to him.

I was told there was a sheet of paper on the driver's seat reminding PDI to remove them before delivery.

(PS, this dealer was not known for Vettes)

Just got back from the dealer. typical maintenance done, and I showed them the TSB and pics for the spacers. they were surprised...14 years later...lol, and they are a Corvette dealer.

I cannot believe the difference in the ride. night and day.

thanks Corvette Forum!

Mind boggling!

You are right! I bought a 2003 a few years back and it rode worse than a truck! I posted the problem on this Forum and a guy asked me if the "shock stuffers" were removed. At the time, this was my 12th Vette and I had never heard of shock stuffers! Sure enough they were still installed. What really got me was that I was the 4th owner and the other owners did not think that the ride was bad! I called the guy that I bought it from and He said that He thought all Corvettes rode like that!

That happened with my 2003 Anniversary as well. On the drive home, every joint in the highway felt like running over a ditch, tooth jarring!

Not unless you or the previous owner pulled them out!
