whats the differance?

Passive dampers have a fixed amount of oil flow restriction, thus a fixed amount of damping (stifness)

An active damper can vary it's damping forced, to react to different driving/road conditions. They do this in 2 ways.

The older F45 system used a variable orifice, which is adjusted by a small actuator on the side of the amped.

The newer F55/MagneRide/MRC system is mechanically simpler, more reliable, and faster. It uses a fixed orifice, and magneto theological fluid. The fluid is full of microscopic metallic flakes. When an electromagnetic field is applied, the fluid thickens/becomes more viscous. The more electricity applied, the more viscous the fluid becomes, the former the damper becomes.

thank's moistcabbage for that explanation.it was better than the lady at arnott gave me earlier.she just said it only affects the escalade like at 90 to 120 mph.so i told her i barely drive over 75 she said than it wouldnt affect my driving if i switch to passive shocks.

That's a bs claim they use to sell they're crap shocks

My mom's 02 stiffens at 45+ and is completely different from passive shocks

i thought she was confused.because i was not asking about a super car to be driven 100 mph +

It's not a speed sensitive system. It's CVRSS (Continuously Variable Road Sensing Suspension), or MagneRide. Both systems "continuously" change the damping force based on many inputs. It's also tied into the stability system. That said, most drivers won't notice much difference unless they're driving pretty aggressively.

good info thanks

Um yes it is as it shows in my gm service manual that the suspension control module gets a speed feed from the pcm
The stability system is part of the Ebcm and also gets a speed sensor feed

Vehicle speed is one of many inputs.

Thanks for the info Mr. Cabbage. Some of us did not know.

I just installed rear air Bilstein AS-2700s on my 2006 ESV. I can't tell the difference in the ride from the OEM ones. Other than they don't leak air anymore! Saved me over $800 vs going OEM.

Did the oem shocks work?
If they was blown then you don't know the difference

They had a slow leak, so I'm assuming the dampening system was working.

how much it cost you?

Was the service ride control message displaying on the information center?

If so then the system was in passive mode

No, there was no DIC message. I had a really slow leak in the shocks after they would pump up. Bladders would be full when I stopped the truck, but then within 30-40mins would be soft. Truck ran good, and I'm liking the ride on the Bilsteins. Also my compressor isn't working as hard now.

A slow leak will cause the system to shut the compressor off due to overheating
Though it won't always show the message

I spent a little over 550 for my AC Delco bilsteins right off Amazon
