Designed to restore controlled, factory-style ride quality to the rear of your vehicle with the Monroe OESpectrum Rear Suspension Shock Absorber (MPN 5818). This is the rear-position damper, and it drops in as a direct-fit replacement on many vehicles, among them the 1968-1969 Chevrolet Camaro, 1967-1973 Toyota Corona and 1977-1979 Ford Thunderbird. See the "Vehicles it fits" section for the full list.
- Twin Technology Active Control System: delivers control under most driving conditions while isolating impact-related noise, vibration and harshness.
- Full displaced valving: tuned specifically to each vehicle and paired with a larger bore for more efficient damping control and a smooth, consistent ride.
- PTFE-banded piston: provides consistent sealing between the piston and pressure tube for better control and increased durability.
- Nitrogen gas-charge: maintains tire-to-road contact by reducing aeration and shock fade, and a self-lubricating fluid seal helps limit friction against the piston rod.
Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee. Shocks work as a pair on an axle, so replacing both rear units together is recommended for balanced, even ride control. If worn rear shocks are the cause of excessive bouncing, poor ride control, or reduced stability, this unit replaces them.

Frequently Asked Questions
What position does this shock absorber fit?
It is cataloged as a rear suspension shock absorber, so it mounts at the rear axle position on the listed applications.
Is this sold individually or as a pair?
This listing is for one shock absorber. Because shocks work in pairs on an axle, replacing both rear units together is recommended for even, balanced ride control.
What are signs my rear shocks may need replacing?
Excessive bouncing after bumps, poor ride control, squat, and reduced stability can indicate worn shocks. Diagnose the cause before replacing.
What kind of gas charge does the 5818 use?
It uses a nitrogen gas-charge that maintains tire-to-road contact by reducing aeration and shock fade for improved ride and handling.
Does the 5818 come with a warranty?
Yes. It is backed by Monroe's Limited Lifetime Warranty and the exclusive Feel the Difference Guarantee.
