KYB KG5450 Suspension Shock Absorber - Front

KYB Gas-a-Just Front Shock Absorber

The KYB Gas-a-Just KG5450 is a monotube front shock absorber built to restore OE-style control on GM compact trucks and SUVs. It uses separate hydraulic and high-pressure gas chambers for quick response, stable damping, and a more controlled ride under load.

Designed for applications such as the Chevrolet S10, GMC Sonoma, Chevrolet Blazer, and GMC Jimmy, this KYB Gas-a-Just shock absorber is a direct-fit suspension service part for front-end replacement on a wide range of GM platforms.

Key Features

• Monotube design separates gas and oil for fade-resistant operation and fast response
• High gas pressure improves steering response and suspension control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Valving and components are tuned for GM truck applications
• Supports vehicles that tow, work, or run larger tires and wheels
• Part number KG5450 for easy identification and ordering

Product Details

The Gas-a-Just line is KYB’s monotube shock absorber series for drivers who want firmer control than a standard twin-tube design. KG5450 uses an air-free hydraulic working area for responsiveness and a separate nitrogen gas chamber with a floating piston to maintain consistent damping during normal driving and sudden suspension movement. That design helps the front suspension stay composed on rough pavement, during braking, and when carrying added load.

Fitment includes 1982-2005 Chevrolet S10 and S10 Blazer, 1991-2004 GMC Sonoma and Jimmy, 1983-1991 GMC S15 Jimmy, 1982-1990 GMC S15, and 1996-2000 Isuzu Hombre. This part number KG5450 is a front shock absorber for these applications and is commonly searched as a KYB front shock for Chevrolet S10 and GMC Sonoma replacement.

This part cross-references Monroe Shocks & Struts 911516 for the same application.
