The kit provides application-specific tuning for enhanced control. The heavy-gauge calibrated coil springs deliver maximum performance without increasing ride harshness.
3.7. Integrated Load-Adjusting Shock
The kit includes a Monroe load-adjusting shock, which assists in maintaining ride height when the vehicle is loaded with additional weight, up to 1,200 lbs. Note that the actual capacity is limited by the vehicle's overall suspension, tires, and transmission capabilities. Consult your vehicle owner's manual for specific details.
4. Setup and Installation
Installation of the Monroe 90007C conversion kit is designed to be a bolt-on process. It is recommended that installation be performed by a qualified automotive technician to ensure proper fitment, safety, and performance. The kit includes full instructions for the installation procedure.
4.1. Pre-Installation Checks
- Verify that the kit is correct for your specific vehicle model and year.
- Inspect all components for any shipping damage or manufacturing defects before beginning installation.
- Ensure you have all necessary tools and safety equipment.
4.2. Installation Procedure
Refer to the detailed instructions provided within the kit packaging for step-by-step guidance. General steps typically involve:
- Safely lifting and securing the vehicle.
- Removing the existing air suspension components.
- Installing the new Monroe shock/strut and coil spring assemblies.
- Connecting all necessary hardware and ensuring proper torque specifications are met.
- Lowering the vehicle and performing a final inspection.
The design ensures that the air suspension warning light will remain off after successful installation.
5. Operating Principles
The Monroe 90007C kit converts a vehicle's active air suspension system into a passive, conventional suspension system. Instead of air bladders and an air compressor, the vehicle's rear suspension will rely on traditional coil springs and hydraulic shock absorbers. The integrated load-adjusting shock features a heavy-gauge calibrated coil spring that provides continuous support and assists in maintaining ride height under varying load conditions, up to its specified capacity. This system operates mechanically, providing consistent damping and spring support without the need for electronic controls or air pressure.
6. Maintenance
Conventional suspension components generally require less maintenance than air suspension systems. However, regular inspection is crucial for longevity and performance.
- Periodic Inspection: Annually or during routine vehicle service, inspect the shocks, springs, and mounting hardware for signs of wear, damage, corrosion, or leaks.
- Cleaning: Keep the suspension components free from excessive dirt, salt, and debris, especially in harsh weather conditions, to prevent premature corrosion.
- Alignment: After any significant suspension work, it is advisable to have a wheel alignment performed to ensure proper vehicle handling and tire wear.
No specific user-serviceable parts are present within the sealed shock absorber units.
7. Troubleshooting
While designed for reliability, certain issues may arise. This section provides general guidance.
7.1. Ride Height Concerns
- Vehicle Sits Too High: It is common for the vehicle to sit slightly higher immediately after installation. The suspension typically settles to its intended ride height after a few hundred miles of driving. If the ride height remains excessively high or uneven after this period, re-check installation for proper seating of components.
- Vehicle Sags: If the vehicle sags, especially under load, ensure that the load capacity of the kit (up to 1,200 lbs) is not exceeded. Verify that the components are correctly installed and not damaged.
7.2. Ride Quality Issues
- Stiff Ride: A conventional suspension may feel firmer than an air suspension. If the ride is excessively stiff or uncomfortable, ensure all mounting bolts are torqued to specification and no components are binding.
- Noises (Clunking, Squeaking): Investigate any unusual noises. These often indicate loose hardware, improper component seating, or interference with other vehicle parts. Re-check all connections and ensure adequate clearance.
7.3. Air Suspension Light On
The kit is designed to keep the air suspension light off. If it remains illuminated, double-check all electrical connections related to the air suspension system's deactivation or bypass, as per the installation instructions. In some cases, a diagnostic scan tool may be required to clear fault codes from the vehicle's computer.
For persistent or complex issues, it is recommended to consult a professional automotive technician.
