KYB KG4611A Shock Absorber - Front

KYB Gas-a-Just Front Shock Absorber

The KYB Gas-a-just KG4611A is a front suspension shock absorber built for Toyota applications that need firmer control and quicker response than a conventional twin-tube design. It uses a monotube layout with separate gas and oil chambers to maintain consistent damping during normal driving and under heavier load conditions.

Compatible With 1967-1983 Toyota Corona and 1970-1983 Toyota Pickup front suspension applications, the KYB Gas-a-just KG4611A is a direct-fit performance upgrade for drivers looking to restore control and reduce fade. This part number is also referenced as KG4611A for easy catalog matching.

Key Features

• Monotube shock design with separate gas and oil chambers for responsive damping
• Up to 25% more damping performance than original equipment shocks
• Higher gas pressure improves steering response and control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Built for Toyota-specific valving and suspension tuning
• Supports vehicles that tow, work, or use larger, heavier tires and wheels
• Helps maintain suspension performance for electronic safety systems

Product Details

The Gas-a-Just line is KYB’s monotube shock absorber series, engineered for applications where consistent damping matters. KG4611A uses a high-pressure design that separates the gas charge from the hydraulic fluid, which helps reduce fade from aeration and delivers immediate response when the suspension is loaded. The result is a front shock absorber that stays controlled during braking, cornering, and uneven road conditions on Toyota Pickup and Toyota Corona models.

This part cross-references Monroe Shocks & Struts 32258 for the same application.

What It Helps Address

• Excessive front-end bounce after bumps
• Reduced steering response and vague handling
• Shock fade during repeated suspension movement
• Fluid leakage caused by seal wear
• Loss of control on vehicles carrying heavier tires, wheels, or work loads
