- Record ride height and current adjuster settings, support the vehicle at approved lifting points, and follow the current Toyota and ARB procedures.
- Install the coilover and reservoir in the specified orientation without twisting or sharply bending the hose.
- Torque all fasteners at the specified suspension position and confirm hose, brake-line, sensor, tire, wheel, and body clearance through travel and steering lock.
- Set compression and rebound only with the supplied adjuster and within ARB guidance for the vehicle load and use.
- Complete a professional alignment and any required driver-assistance calibration, then recheck torque and clearances after the initial driving interval.
