KYB KG5419 Shock Absorber - Rear

KYB Gas-a-Just Rear Shock Absorber

The KYB Gas-a-just KG5419 is a monotube rear shock absorber built for older Jeep, Ford, Chevrolet, and GMC applications that need firmer control and consistent damping. It uses separate gas and oil chambers for quick response, reduced fade, and stable ride quality during everyday driving and heavier-duty use.

Gas-a-Just Line Details

KYB Gas-a-just shocks are tuned for vehicles that work harder than a standard commuter car. The monotube design adds damping performance over OE shocks, while the high-pressure nitrogen charge helps maintain response when towing, carrying load, or running larger tires and wheels. The KG5419 also uses a triple chrome plated piston rod to help reduce seal wear and fluid leakage.

Key Features

• Adds up to 25% more damping performance over original equipment shocks
• Monotube construction separates gas and oil for fade-resistant operation
• High gas pressure improves steering response and control
• Triple chrome plated piston rod helps reduce seal wear
• Dust cover included
• Lower mount type: E2(16X32)
• Upper mount type: E2(16X32)
• Compressed length: 12.56 in; extended length: 19.84 in; stroke length: 7.28 in

Detailed Description

Part number KG5419 is a KYB Gas-a-just rear suspension shock absorber designed for direct replacement on a wide range of classic Jeep, Ford, Chevrolet, and GMC trucks and SUVs. It is a strong choice for rear suspension service on vehicles such as the Jeep CJ5, Jeep CJ7, Ford Bronco, and Ford F-250 where added damping and quicker response are needed. This part cross-references Monroe Shocks & Struts 34905 for the same application.

What It Helps Address

• Excessive rear bounce or oscillation
• Reduced control on rough roads or uneven pavement
• Shock fade during repeated suspension movement
• Loose steering feel caused by worn rear damping
• Ride instability on trucks and SUVs with heavier tires or load demands

Installation Notes and Tips

Verify compressed length, extended length, and mount style before installation. KG5419 uses E2(16X32) upper and lower mounts, so matching the existing hardware and bracket style is important for proper rear suspension fitment. Confirm the vehicle is listed in the fitment data for the exact year, make, model, and rear position before ordering.

Quality Assurance

KYB designs the Gas-a-just line with monotube valving and high-pressure gas separation to maintain consistent damping response. The KG5419 is built for direct-fit rear suspension service on confirmed applications and follows KYB’s performance-focused shock absorber design standards.
