About the OESpectrum Light Truck Shock Absorber Line

The OESpectrum Light Truck Shock Absorber line by Monroe is designed to meet or exceed original equipment specifications for light trucks and SUVs. This product line focuses on delivering consistent damping performance and durability, making it suitable for vehicles that require reliable suspension components for both daily driving and light hauling. The 37156 part number is part of this line, ensuring compatibility and quality for GM models such as the Pontiac Montana and Saturn Relay.

Detailed Product Description

The Monroe 37156 shock absorber features a compressed length of 12.75 inches and a travel length of 7.5 inches, providing the necessary stroke for effective suspension travel. Its extended length measures 20.25 inches, accommodating the suspension geometry of compatible vehicles.
