The 2000-2006 GMC Yukon is built with the following suspension components:
2000-2006 GMC Yukon Air/Electronic/Magnetic Shocks (x2)- shocks that contain an air bladder or magnets whose dampening capabilities is controlled by the suspension control module.
2000-2006 GMC Yukon Coil Springs (x2/x4)- what we love! Coil springs hold the vehicle up but be careful, they are rated for and designed to work with the rest of the suspension system, so when you change air shocks to passive shocks, then you will need a different rated coil spring that works well with the new type of shocks other
2000-2006 GMC Yukon Torsion Bar- on some 4x4 models. Adjustable horizontal bar on the front of the vehicle that holds the vehicle off the ground
2000-2006 GMC Yukon Struts (x2)- on some 4x4 models. A type of shock absorber, it is a piece of metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle.;
2000-2006 GMC Yukon Shock Absorbers (x4)- a metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle.
2000-2006 GMC Yukon Height Sensors (x4)- a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.
2000-2006 GMC Yukon Air Lines- tubes that run from a compressor to the air which carry pressurized air to the air bags in order to adjust the height of the vehicle, respectively.
2000-2006 GMC Yukon Compressor Assembly- creates/sends pressurized to active suspension components. When the air suspension starts leaking, the compressor/pump starts working harder to try to keep the system inflated. By the time air suspension leaks down completely, sitting the vehicle on its tires, the compressor will either have failed or be well on its way to full failure. Buying replacement struts and taking the time to install them only to find out the compressor still needs to be replaced can be very frustrating, time-consuming, and expensive.
2000-2006 GMC Yukon Dryer- prevents moisture build-up inside of air suspension parts.
2000-2006 GMC Yukon Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicles correct ride height.
2000-2006 GMC Yukon O-rings- Although they are the least expensive parts of the air suspension, they are responsible for maintaining the seal where all of the air lines connect. Be sure to replace the O-rings when repairing any air suspension system.
