Smooth out the ride and restore factory-level control with the Monroe OESpectrum Suspension Shock Absorber 5840, a front-position shock designed to bring a vehicle's original drivability and handling precision back. It's a direct-fit replacement for a long list of GM applications, including the 1975 Buick Apollo, 1973-1987 Buick Regal, 1973-1987 Chevrolet El Camino, 1973-1988 Chevrolet Monte Carlo, 1973-1988 Oldsmobile Cutlass Supreme, and 1973-1987 Pontiac Grand Prix — see the Buyer's Guide tab for the full list of 32 applications.
- Reduced NVH: Twin Technology Active Control System delivers control across most driving conditions while isolating impact-related noise, vibration and harshness.
- Exceptional handling: Full displaced valving, tuned to each vehicle, adjusts to road extremes, and a larger bore provides more efficient damping control for a consistent, smooth ride.
- Control and durability: A PTFE-banded piston provides consistent sealing between the piston and pressure tube for better control and increased durability.
- Consistent performance: OE all-weather fluid resists breakdown at temperature extremes, while a nitrogen gas charge maintains tire-to-road contact by reducing aeration and shock fade.
A self-lubricating fluid seal retains gas and reduces friction against the piston rod to help limit premature wear. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.
