Key Features
- Exceptional Handling: Features full displaced valving, specifically tuned for each vehicle, which adjusts to road extremes. A larger bore provides efficient damping control for consistency and a smooth ride.
- Improved Stability: Utilizes ASD (Acceleration Sensitive Damping) valving technology and a fluon-banded piston to deliver greater control and handling, enhancing ride comfort.
- Enhanced Performance: Nitrogen gas-charge maintains tire-to-road contact, improving ride and handling by reducing aeration and shock fade.
- Consistent Ride Quality: OE all-weather fluid contains special additives to assist with extreme temperatures and help reduce oil breakdown, ensuring consistent performance.
- Durability: A self-lubricating fluid seal retains gas and reduces excessive friction against the piston rod, helping to prevent premature wear.

2. Installation Guide
Proper installation is crucial for the performance and safety of your vehicle. It is highly recommended that installation be performed by a qualified automotive technician. Always refer to your vehicle's service manual for specific torque specifications and procedures.
Safety Precautions
- Always wear appropriate personal protective equipment, including safety glasses and gloves.
- Ensure the vehicle is securely supported on jack stands or a lift before beginning work. Never rely solely on a jack.
- Use appropriate tools for removal and installation.
- Be aware of spring compression and release. Use a spring compressor if necessary and follow its instructions carefully.

4. Maintenance and Care
Regular inspection of your shock absorbers can help ensure their longevity and continued performance. While Monroe OESpectrum shocks are designed for durability, periodic checks are recommended.
Recommended Checks
- Visual Inspection: Periodically inspect the shock absorbers for any signs of fluid leaks, dents, or damage to the housing.
- Bushing Condition: Check the rubber bushings at the mounting points for cracks, wear, or deterioration. Worn bushings can lead to noise and reduced effectiveness.
- Mounting Hardware: Ensure all mounting bolts and nuts are secure and properly torqued.
- Dust Shield: Verify the dust shield is intact and properly covering the piston rod to protect it from road debris.

The self-lubricating fluid seal within the shock absorber is designed to maintain gas and reduce friction, contributing to its long service life. No internal maintenance is required for the shock absorber unit itself.
5. Troubleshooting Common Issues
If you experience changes in your vehicle's ride quality or suspect an issue with your shock absorbers, consider the following common symptoms:
Symptoms of Worn Shock Absorbers
- Excessive Bouncing: The vehicle continues to bounce after hitting a bump, indicating poor damping.
- Nose Dive During Braking: The front of the vehicle dips excessively when braking.
- Squat During Acceleration: The rear of the vehicle sags excessively during acceleration.
- Uneven Tire Wear: Scalloped or cupped tire wear patterns can indicate inadequate suspension control.
- Fluid Leaks: Visible oil or fluid leaking from the shock absorber body.
- Unusual Noises: Clunking or rattling sounds from the suspension area.
If you observe any of these symptoms, it is advisable to have your vehicle inspected by a professional technician. Worn shock absorbers can compromise vehicle safety and handling.
