Keep your light truck planted and composed over rough pavement with the Monroe Reflex Front Suspension Shock Absorber 911043. Built for vehicles with a higher center of gravity, it drops in as a front replacement for the 1988-1999 Chevrolet K1500 and 1988-1999 GMC K1500, the 1988-2000 Chevrolet K2500 and 1988-2000 GMC K2500, and many related SUVs and Suburbans.
- Improves stability: ASD (Acceleration Sensitive Damping) valving automatically adjusts to impacts, helping reduce roll and dive on vehicles with a higher center of gravity.
- Exceptional handling: Full displaced valving is tuned to the vehicle and a larger bore provides more efficient damping control for a consistent, smooth ride.
- Consistent ride: OE all-weather fluid with special additives helps handle temperature extremes and reduce oil breakdown, while a larger reserve tube holds more fluid to run cooler.
- Control and durability: A Fluon-banded piston seals consistently against the pressure tube, and a nitrogen gas charge helps maintain tire-to-road contact by reducing aeration.

Frequently Asked Questions
Where does this shock mount?
It is a front suspension shock absorber. It installs at the front axle position on the listed applications; check the Buyer's Guide tab to confirm fitment for your vehicle.
What is ASD valving?

What are signs my front shocks need replacing?
Common signs include excessive bouncing after bumps, nose dive under braking, and reduced control. If a worn front shock is the cause, this unit replaces it; diagnose the cause first.
