Trucks With Option Zx3, Manual Selectable Ride

[Nate1958]

I have a 2000 Silverado LS 5.3L two wheel drive with option Zx3. Shocks are still the original one made by delphi (orange color). Does anyone know how long this shocks will last? I have close to 82,000 miles on them. Also, does anyone know what the three digit code means right after the manufacturers part number? Example 15759180 T3W.

 

 

 

Thanks,

Nate

Don't know how long they last but this is how they work..

 

Selectable Ride Description and Operation

The selectable ride (SR) suspension system allows the driver to choose between 2 distinct damping levels, firm and normal.

The SR dampers are gas charged units which provide damping by forcing hydraulic fluid through internal orifices within each shock in order to resist suspension movement. Each shock contains an internal solenoid actuator that the SR switch controls. This solenoid actuator controls the size of the orifice that the hydraulic fluid is forced through, thus altering the ride characteristics of the vehicle.

Voltage is supplied to the switch via the ignition1 voltage circuit from the SEO IGN Fuse. When the system is on, the voltage is supplied to terminal A of each shock providing firmer damping. Ground is supplied to terminalB of each shock

 

ZX3 Ride Control/RC4WD SWB - $420

 

It was part of the NHT pkg. on the GMT800 trucks,It was also part of the NYS Quadrasteer pkg. on those trucks,as well as being an individual option on certain other models.

It was even available with the Z71 suspension as RPO code "FW1"
