KYB Gas-a-just Rear Monotube Shock Absorber for Select 2007-2024 Chevrolet Silverado & GMC Sierra 1500 (555055)

Fits select 2007-2024 Chevrolet Silverado 1500 and GMC Sierra 1500 models, including LD, LTD, and Limited editions.

The KYB Gas-a-just is a high-pressure monotube shock absorber designed as a direct OE replacement to restore your truck's original handling and control. Unlike standard twin-tube shocks, the Gas-a-just features two separate working chambers: a hydraulic piston and valve area for immediate responsiveness, and a second high-pressure nitrogen gas chamber with a floating piston. This design eliminates aeration and foaming, providing a comfortable ride during routine driving while delivering instant performance and stability when demand increases.

Maintaining proper suspension damping is critical for the performance of modern electronic safety systems, such as ABS and stability control. The KYB Gas-a-just ensures these systems operate within their intended parameters by keeping tires firmly planted on the road surface.
