Help smooth out the ride and keep the rear tires planted with the Monroe Reflex Rear Suspension Shock Absorber 911085, a direct-fit rear-position replacement built for trucks, vans and SUVs with a higher center of gravity. It fits many vehicles, among them the 1995-2000 Chevrolet Tahoe, 1995-1999 GMC Yukon and 1996-2014 Chevrolet Express 1500 — see the "Vehicles it fits" section for the full engine-level list.
- ASD valving: Acceleration Sensitive Damping adjusts to impacts to help reduce roll and dive on higher-center-of-gravity vehicles.
- Full displaced valving: tuned to the vehicle, with a larger bore for more efficient damping control and a consistent, smooth ride.
- All-weather fluid: OE fluid with additives for extreme temperatures and reduced oil breakdown, and a larger reserve tube that holds more fluid to run cooler.
- Nitrogen gas charge & Fluon-banded piston: maintains tire-to-road contact by reducing aeration; the banded piston seals consistently against the pressure tube for durability.
Worn rear shocks may show up as excessive bounce, nose-dive under braking, or body roll — if your original rear shock is the cause, this replaces it. Backed by Monroe's Limited Lifetime Warranty. Sold individually; replacing both rear shocks together is recommended for balanced ride control.

Frequently Asked Questions
Does this shock fit the front or rear?
It is a rear suspension shock absorber. Sold individually; replacing both rear shocks together as a pair is recommended for balanced, even ride control.
What is ASD valving?
Acceleration Sensitive Damping automatically adjusts the shock to absorb impacts, helping reduce roll and dive on vehicles with a higher center of gravity.
What vehicles does the 911085 fit?
It fits many vehicles, among them the 1995-2000 Chevrolet Tahoe, 1995-1999 GMC Yukon and 1996-2014 Chevrolet Express 1500. See the "Vehicles it fits" section for the full list.
What are signs my rear shocks need replacing?
Excessive bouncing, nose-dive under braking, or body roll can indicate worn shocks. Diagnose the cause first; if the rear shock is the culprit, this replaces it.
Is this a gas-charged shock?
Yes. A nitrogen gas charge helps maintain tire-to-road contact by reducing fluid aeration for improved ride and handling.
