2003-2009 Hummer H2 2WD & 4WD Rear Air Suspension Conversion/Delete Kit With Front And Rear Shocks (HA1RF)

Replaced Components
The 2003-2009 Hummer H2 is built with the following suspension components: 2003-2009 Hummer H2 Rubber Air Springs (x2)- (models with air suspension only). Commonly referred to as air bags, a plastic and rubber bag that uses pressurized air as a cushion (instead of a metal coil spring) to support the weight of the rear of the vehicle. Leaks in the rubber portion of the air springs are the number one cause of all air suspension leaks. Since all air springs go bad at about the same rate, if one is leaking, the others will not be far behind. For a proper repair, all of them need to be replaced at the same time . 2003-2009 Hummer H2 Shock Absorbers (x4)- Metal Tubing filled with gas-charged hydraulic fluid that controls bouncing motion and dampens vibration caused by travel on rough road surfaces. 2003-2009 Hummer H2 Air Compressor Assembly- Creates and sends pressurized air to the air springs. When the air suspension starts leaking, the compressor (also known as an air pump) starts working harder to try to keep the system inflated. By the time air suspension leaks down completely, the compressor will either have failed or be permanently damaged to a point it can't make enough PIS to inflate the system. 2003-2009 Hummer H2 Height Sensors (x4)- A linkage located near each wheel that constantly measures the height of the vehicle and reports this information back to the control module. The ride height sensor is a moving part and will eventually wear out. 2003-2009 Hummer H2 Suspension Control Module- This vehicle is equipped with a computer known as the suspension control module. This module is the brain of the suspension system and it reads all of the signals that are being sent by the height sensors and determines if the vehicle needs to be raised or lowered. 2003-2009 Hummer H2 Rubber 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.

Suspension Failure Signs
The most obvious sign of air suspension trouble on your 2003 to 2009 Hummer H2 is a loss of three to five inches of ride height in the rear of the vehicle. The most common reason for failure of the system is tiny cracks in the rubber air springs create leaks in the system and overwork an onboard air compressor. Other signs of trouble include a noisy air compressor that runs too often and/or an illuminated supension warning light in the instrument cluster. At this point, suspension failure is advanced and the H2 owner is facing a repair bill that could be massive. Experience technicians recommend replacing ALL of the major components in the air suspension system for the best chance of a successful repair. A complete overhaul of the system can cost thousands. This is why the Strutmasters suspension conversion kit has been such a popular alternative with Hummer H2 owners. The Strutmasters conversion kit takes care of the problem permanently at a fraction of the cost!

OEM Replacement Cost
'+ Air Compressor Assembly ($1,316/compressor) + Replacement Shocks ($130/shock) + Rubbber Air Springs ($180/air springs) = TOTAL: Over $2,196 (and that doesn't even include replacing electronic components that are known to fail such as the height sensors).
