Smooth out the ride and restore controlled damping with the Monroe OESpectrum Front Suspension Shock Absorber 37178. This nitrogen gas-charged front shock is a direct-fit replacement for the 2000-2006 Chevrolet Suburban 1500, 2000-2006 Chevrolet Tahoe, 2000-2006 GMC Yukon, and 2000-2006 GMC Yukon XL 1500 — see the "Vehicles it fits" section for engine-level applications. Monroe OESpectrum light-truck shocks are designed to help restore a vehicle's original factory drivability and handling while filtering out impact-related noise, vibration, and harshness.
- Exceptional handling: Full displaced valving tuned to the vehicle adjusts to road extremes, while a larger bore delivers more efficient damping control for a consistent, smooth ride.
- Control and durability: A PTFE-banded piston provides consistent sealing between the piston and pressure tube for better control and increased durability.
- Reduced NVH: The Twin Technology Active Control System delivers control under most driving conditions while isolating impact-related noise, vibration, and harshness.
- Improved performance: A nitrogen gas charge helps maintain tire-to-road contact by reducing aeration and shock fade.
OE all-weather fluid with special additives helps resist breakdown at temperature extremes, and a self-lubricating seal retains gas while reducing friction against the piston rod. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.
