Help bring back the smooth, controlled ride your classic was built for with the Monroe OESpectrum 5839 rear shock absorber, a direct-fit replacement for the 1973-1976 Ford Thunderbird, 1972-1976 Lincoln Mark IV and 1977-1979 Lincoln Mark V. Monroe designed its OESpectrum passenger car shocks to help restore a vehicle's original factory drivability. They give precise handling and control while filtering out noise, vibration and harshness.
- Reduced noise, vibration and harshness: The Twin Technology Active Control System provides control in most driving conditions and isolates noise, vibration and harshness from impacts.
- Handling: Full displaced valving, tuned specifically to each vehicle, adjusts to road extremes. The larger bore provides more efficient damping control for a consistent, smooth ride.
- Control and durability: A PTFE-banded piston seals consistently against the pressure tube. A self-lubricating fluid seal retains gas and reduces excess friction against the piston rod to help limit premature wear.
- Consistent ride: OE all-weather fluid contains special additives that help it handle extreme temperatures and reduce oil breakdown. A nitrogen gas charge helps keep the tires in contact with the road by reducing aeration and shock fade.
Signs a rear shock may need replacing include excessive bouncing after bumps, a floating or wallowing ride, rear-end squat under acceleration, fluid leaking from the shock body and uneven tire wear. Replacing both rear shocks together is recommended for balanced handling. This shock is backed by Monroe's Limited Lifetime Warranty and its exclusive Feel the Difference Guarantee. See the "Vehicles it fits" section for engine-level fitment details.

Frequently Asked Questions
Which vehicles does the Monroe 5839 rear shock fit?
It is a direct-fit rear shock absorber for the 1973-1976 Ford Thunderbird, 1972-1976 Lincoln Mark IV and 1977-1979 Lincoln Mark V. Check the "Vehicles it fits" section for engine details.
What does a rear shock absorber do?
It dampens spring movement at the rear of the vehicle. This helps control body motion and keep the tires in contact with the road while filtering out noise, vibration and harshness.
What technology does the OESpectrum 5839 use?
It uses the Twin Technology Active Control System, full displaced valving tuned to each vehicle, a PTFE-banded piston, OE all-weather fluid, a nitrogen gas charge and a self-lubricating fluid seal.
What are signs my rear shocks may need replacing?
Signs include excessive bouncing after bumps, a floaty ride, rear-end squat under acceleration, fluid leaking from the shock body and uneven tire wear. Inspect the suspension to confirm the cause before replacing parts.
Should I replace both rear shocks at the same time?
Replacing both rear shocks together is recommended so damping stays balanced from side to side. Monroe backs this shock with its Limited Lifetime Warranty and Feel the Difference Guarantee.
