Smooth out the ride and restore firm suspension control at the rear axle with the Monroe OESpectrum Rear Suspension Shock Absorber 37064. It installs as a direct-fit rear shock for the 1985-2005 Chevrolet Astro and 1985-2005 GMC Safari, designed to help return the vehicle toward its original factory drivability while filtering out impact-related noise, vibration, and harshness. See the Buyer's Guide tab for the full application list.
- Exceptional handling: Full displaced valving is tuned to each vehicle and works with a larger bore for more efficient, consistent damping control.
- 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 helps isolate impact-related noise, vibration, and harshness under most driving conditions.
- Nitrogen gas-charge: Helps maintain tire-to-road contact by reducing aeration and shock fade for improved ride and handling.
OE all-weather fluid carries additives to assist with extreme temperatures and help reduce oil breakdown, while a self-lubricating fluid seal retains gas and reduces friction against the piston rod to help limit premature wear. Backed by Monroe's Limited Lifetime Warranty and the Feel the Difference Guarantee.
