Help keep your full-size SUV planted through bumps and body roll with the Monroe Reflex Shock Absorber 911166, a rear suspension shock that installs as a direct-fit replacement for the listed applications. It fits many vehicles, among them the 2000-2006 Chevrolet Tahoe, 2000-2006 GMC Yukon and 2000-2006 Chevrolet Sonora; see the "Vehicles it fits" section for the full list. Built for vehicles with a higher center of gravity, the Reflex line uses Acceleration Sensitive Damping to adjust to impacts on the fly.
- ASD valving: Acceleration Sensitive Damping automatically adjusts the unit to absorb impacts, helping reduce vehicle roll and dive.
- Full displaced valving: Tuned to each vehicle and paired with a larger bore for more efficient damping control, consistency, and a smooth ride.
- All-weather fluid: OE fluid with additives to handle extreme temperatures and help reduce oil breakdown, while a larger reserve tube holds more fluid to run cooler.
- Fluon-banded piston & nitrogen charge: Consistent piston-to-pressure-tube sealing for control and durability; the nitrogen gas charge helps maintain tire-to-road contact by reducing aeration.
Backed by Monroe's Limited Lifetime Warranty and the Feel the Difference Guarantee. This is a rear-position shock; it is sold individually, and replacing both rear shocks together as a matched pair is recommended for balanced handling. See the "Vehicles it fits" section for engine-level fitment.
