2 Safely raise the vehicle according to the manufacturer’s instructions.

3 Deflate and disable the air suspension system according to the manufacturer’s instructions.

4 Remove the applicable rear wheel(s). (Figure 1)

5 Remove the fasteners and paneling under the right side of the vehicle to expose the vehicle’s air suspension valve block. (Figures 2, 3, 4)

6 Locate the valve block and slowly remove the air lines to ensure the air spring is fully deflated. The air hose on the right will deflate the right air spring, and the air hose on the left will deflate the left air spring. (Figure 5)

7 Remove the bottom piston from the lower spring seat by pressing in the two locking tabs and pushing upward on the bottom piston. (Figures 6, 7)

8 Remove the top of the air spring by turning counterclockwise approximately 90 degrees, and pull the air spring out. (Figures 8, 9)

9 Remove the air line from the air spring. Remove the air line fitting from the air hose and discard it. (Figures 10, 11)

10 Place the unused air line in a suitable location, away from friction or heat sources.

Tighten all nuts and bolts to the manufacturer’s specifications during the installation process.

1 Assemble the provided lower coil spring perch and hardware onto the frame of the vehicle. Do not fully tighten yet. (Figures 12, 13, 14, 15)

2 Place the upper coil spring perch onto the coil spring. (Figures 16, 17)

3 Place the new coil spring into the mounting position. The top mount perch will seat into the frame of the vehicle. (Figure 18)

4 Tighten the nut on the lower coil spring perch to the manufacturer’s specifications. (Figure 19)

5 Installation steps apply to both rear sides of the vehicle.

1 Remove the right side trunk paneling to reveal the control module. (Figures 20, 21)

2 Remove the harness connection to the control module. It will remain unplugged. (Figures 22, 23)

3 According to the table below, splice the EBM harness wires to the applicable control module harness wires using the four (4) supplied heat-shrink butt connectors. (Figure 24, 25)

Electronic Bypass Module From To Pin Location Air Suspension Control Module Connections Red Red/Yellow 22 Black Brown 6 Green Lt. Green 25 Blue Orange/Green 24

4 Connect the EBM to the EBM harness. (Figures 26, 27)

5 Secure the wires and the EBM in a suitable location, away from friction or pinch points.

Do not plug the suspension control modules back in. They remain unplugged. There should be no suspension error lights present in the instrument cluster.
