KYB 554248 KG54341 Gas-a-Just Monotube High-Pressure Gas Shock Absorber

The KYB Gas-a-Just KG54341 is a high-pressure monotube gas shock absorber engineered to deliver superior ride control, stability, and handling performance. Sold individually, this shock serves as both an OE monotube replacement and a performance upgrade for vehicles originally equipped with twin-tube shocks.

Dual-Chamber Monotube Design: The Gas-a-Just features two separate working chambers — an air-free hydraulic piston and valve area for responsiveness and control, and a second high-pressure nitrogen gas chamber with a floating piston. Together, they provide a comfortable ride during normal driving while instantly adding performance when road conditions demand it.

Key Features:

• High-pressure monotube design separates gas and oil for fade-free, instant-response operation
• Velocity-sensitive valving automatically adjusts to changing road conditions
• Micro-smooth, hard-chromed piston rod reduces seal wear and extends service life
• Seamless cylinder and eye-rings eliminate seam failures for long-term durability
• Adds up to 25% more damping performance over original equipment shocks
• Limits body roll and nose dive for improved cornering and braking control
• Dust cover included for added protection
• Ideal for vehicles that tow, carry heavy loads, or run larger, heavier wheels and tires
• Supports proper operation of Electronic Stability Control (ESC) systems
• Contains no remanufactured components

What's Included: One (1) Gas-a-Just shock absorber with all necessary washers, bushings, and nuts. Factory shock mounting bolts are reused during installation. Shock boots are sold separately.
