The KYB Gas-a-just has two separate working chambers: An air-free hydraulic piston and valve area for responsiveness and control, and a second high-pressure nitrogen gas area with a floating piston that provides a comfortable ride during normal driving and adds instant performance on demand.\n\u003cul\u003e\n  \u003cli\u003eElectronic safety systems depend on the suspension, brakes and tires operating as the vehicle manufacturer intended.

Its monotube design uses separate working chambers to maintain stable damping performance and help reduce the effects of aeration during demanding driving conditions.\u003c\/p\u003e\u003cp\u003eInside the KYB Gas-a-Just, an air-free hydraulic piston and valve area supports precise suspension control, while a high-pressure nitrogen gas chamber with a floating piston allows the shock to respond automatically to changing road and driving conditions. This design helps provide a comfortable ride during normal driving and additional damping performance when vehicle movement increases. By helping the suspension operate as intended, the KYB Gas-a-Just also supports the proper function of electronic safety systems that depend on the vehicle’s suspension, brakes, and tires.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Product Specifications \u0026amp; Technical Data\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: KYB\u003c\/li\u003e\n\u003cli\u003ePart Number: KG4521\u003c\/li\u003e\n\u003cli\u003eProduct Type: Monotube shock absorber\u003c\/li\u003e\n\u003cli\u003eSeries: Gas-a-Just\u003c\/li\u003e\n\u003cli\u003eConstruction: Monotube design with floating piston\u003c\/li\u003e\n\u003cli\u003eGas Charge: High-pressure nitrogen\u003c\/li\u003e\n\u003cli\u003eApplication Type: Automotive suspension replacement\u003c\/li\u003e\n\u003cli\u003eAir Freight: Prohibited\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eOne KYB Gas-a-Just KG4521 shock absorber\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eDesigned for select 1952–1953 Volkswagen Beetle and 1964–1969 Volkswagen Transporter applications.
