- PTFE coated bearing: Reduces friction during operation between the rod and rod guide, improving durability - on most applications.
- Tenneco shouldered bushings: Shouldered bushing and bonded bushing with sleeve designs prevent (bushing walkout) for improved quality and durability - on most applications.
- Nitrogen gas-charged: For improved ride and handling, helps maintain tire to road contact by reducing aeration - on most applications.
- Loop welding technique: Resistance weld with additional 360-degree weld to provide up to 15,000 lbs. (6,804 kg) tensile strength for maximum durability - when required.
- 2-3/8 inch (60.3 mm) reserve tube: More fluid for more consistent performance - on most applications.
- 1-3/4-inch (44.6 mm) bore: Large bore than most shocks to provide more consistent control.
- .05-inch Pressure tube: Withstanding pressure of 9KPSI.
- 10-stage valving: Reacts to wide range of driving conditions - on most applications.

Troubleshooting
If you experience issues after installing your Monroe Magnum 65415 shock absorber, consider the following common troubleshooting steps:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Excessive Bouncing/Poor Ride | Incorrect installation, damaged shock, or other worn suspension components. | Verify proper installation. Inspect for leaks or damage. Check other suspension parts (springs, control arms). |
| Clunking/Rattling Noise | Loose mounting hardware, worn bushings, or contact with other components. | Check all fasteners for proper torque. Inspect bushings for wear. Ensure adequate clearance. |
| Fluid Leakage | Damaged seal or internal component failure. | A leaking shock absorber typically requires replacement. Contact a qualified technician. |
