- Exceptional handling: Full displaced valving is tuned to the vehicle and a larger bore provides more efficient damping control for a consistent, smooth ride.
- Control and durability: A PTFE-banded piston delivers consistent sealing between the piston and pressure tube.
- Reduced NVH: The Twin Technology Active Control System helps isolate impact-related noise, vibration and harshness.
- Nitrogen gas-charge: Helps maintain tire-to-road contact by reducing aeration and shock fade.
OE all-weather fluid with special additives helps handle temperature extremes and reduce oil breakdown, while a self-lubricating fluid seal helps limit friction against the piston rod. If worn front shocks are behind a bouncy, loose ride, this replaces them. Sold individually; replacing both front shocks as a pair is recommended for balanced control. Backed by Monroe's Limited Lifetime Warranty.
