Monroe 66504 - 60 Series Gas Magnum Shock Absorber

Description:

The Monroe^® Magnum^® Steering Damper is a Spring-Over design specifically engineered for hardworking vehicles with self-steering drop axles. With a thicker nitrocarburized piston rod, large piston bore, large oil chamber, and thicker tube wall, it delivers maximum durability for over-the-road and severe duty applications.

Designed to prevent the shock damage that can lead to poor performance or premature failure on self-steering drop axle vehicles, the Magnum Spring-Over Steering Stabilizer is backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.

• Handles the Load: Stabilizer specifically designed for hardworking vehicles with self-steering drop axles.
• Consistent Performance: All-weather fluid with special additives assists with extreme temperatures; large reserve tube holds more oil to run cooler.
• Strong and Durable: Shouldered and bonded bushing with sleeve prevents bushing walkout (most applications); arc welds up to 360° for durability.
• Exceptional Handling: Full displaced valving delivers better valving range on compression and extension cycles; large bore for more efficient damping and heavy-rate coil spring for control.
• Keeps Water and Debris Out: Plastic dirt shield protects the shock, reducing buildup of debris and premature rod, coil spring, and seal damage.
• Longer Service Life: Multi-lip seal for smooth performance and long life; nitrocarburized piston rod for durability.
• Improves Performance: Nitrogen gas-charge maintains tire-to-road contact by reducing aeration and shock fade.
• Buy with Confidence: Comes with Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.
