- ASD valving: Acceleration Sensitive Damping adjusts to impacts automatically, helping reduce roll and dive on higher-center-of-gravity vehicles.
- Exceptional handling: Full displaced valving tuned to the vehicle, with a larger bore for more efficient damping control and a smooth ride.
- Consistent ride: OE all-weather fluid with additives for temperature extremes, plus a larger reserve tube that holds more fluid to run cooler.
- Built to last: Fluon-banded piston for consistent sealing, a nitrogen gas charge that reduces aeration to help maintain tire-to-road contact, and a self-lubricating seal that reduces friction against the piston rod.
Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.
