Quick Strut Features
They feature pre-assembled replacement bearing plate, upper and lower spring isolators, upper spring seat, coil spring, boot kit, and a premium strut. This breakthrough design saves on installation time by eliminating having to disassemble components and compress the coil spring prior to installation. Each Quick-Strut® assembly features application-engineered valving to optimize each vehicle's unique ride and handling characteristics. Available for popular passenger car, light truck and SUV applications.

• Pre-Assembled Upper Strut Mount: OE-style bearings, SAE-grade nuts and bolts, Superior rubber-to-steel bonding, Plated steel for longer wear, All components manufactured to meet or exceed OE performance
• Bearing Plate: The new bearing plate helps ensure consistent, precise steering return by eliminating 'memory steer.' Helps eliminate steering noises commonly associated with worn or corroded bearings. Also improves overall steering smoothness
• Upper Spring Seat: Engineered to complement the ride control characteristic of the corresponding premium Monroe® strut and upper strut mount. The upper spring seat provides consistent performance without transmitting noise or vibration into the chassis.
• Coil Spring: Manufactured from high-quality U.S. steel, each coil spring is precisely calibrated to support the vehicle's weight and help ensure correct ride height. Each spring is painted or powder-coated for excellent rust resistance
• Boot Kit: The durable strut boot protects the strut rod and seal from dirt and debris. The premium bumper prevents component damage when the suspension bottoms out
• Spring Isolators: Prevents metal to metal contact and helps eliminate noise between the spring and spring seat
• Premium Strut: Premium strut technology based on application. Each strut features application-engineered valving to complement each vehicle's unique ride and handling characteristics

OE Spectrum Features
The Monroe® OESpectrum® shock absorbers feature the latest original equipment valving technologies for domestic and foreign nameplate applications. Monroe OESpectrum units provide an unprecedented level of handling precision and control while filtering out ride harshness. This unique blend of control and comfort is made possible through Tenneco's Twin Technology™ Active Control System, an exclusive internal damping control technology.

Tenneco's Twin Technology consists of its latest Impact Control Valve (ICV), which delivers exceptional control under virtually all driving conditions, and a patented Low Speed Tunability (LST) piston design that isolates impact-related noise, vibration and harshness.

Features

• All Weather Fluid: Contains special modifiers to reduce friction and ensure smooth rod reaction.
• Full Displaced Valving: Tuned specifically for each application, this valving automatically adjusts to road extremes to provide consistency and ride
• Fluon Banded Piston: The fluon band provides consistent sealing between the piston and pressure tube which delivers better control and increased durability.
• 1-3/16 inch Bore: Larger bore than most shocks to provide more efficient and consistent control
• Twin Technology: Impact Control Valve (ICV), delivers exceptional control under virtually all driving conditions, and patented Low Speed Tunability (LST) piston design that isolates impact-related noise, vibration and harshness.
• Nitrogen Gas Charged: For improved ride and handling, helps maintain tire to road contact by reducing aeration - on most applications
• 1/2 inch Diameter Piston Rod: Nitrocarburized rod for long service life. On non-dust shield units only.
• Special Seal: 'Self-lubricating' fluid seal designed to retain gas without excessive wear or friction.
