Smooth out rough roads and keep your vintage Chevy and GMC light truck planted with the Monroe OESpectrum Suspension Shock Absorber 37040. Designed to help restore a vehicle's original factory drivability and ride control, this light-truck shock installs in the front, rear, or front outer position as a direct-fit replacement across a wide range of applications — including the 1969-1974 and 1987-1991 Chevrolet Blazer, 1975-1986 Chevrolet K10, 1969-1986 Chevrolet K10 Suburban, 1970-1991 GMC Jimmy, and 1979-1986 GMC K1500. See the Buyer's Guide tab for the full list of 48 applications.
- Exceptional handling: Full displaced valving is tuned specifically to each vehicle, and a larger bore provides 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 isolates impact-related noise, vibration and harshness.
- Nitrogen gas-charge: Reduces aeration and shock fade to help maintain tire-to-road contact for improved ride and handling.
OE all-weather fluid contains special additives to assist with temperature extremes and help reduce oil breakdown, while a self-lubricating fluid seal retains gas and reduces friction against the piston rod. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.
