KYB KG5190 Shock Absorber - Rear

KYB Gas-a-just Rear Shock Absorber

The KYB Gas-a-just KG5190 is a rear monotube shock absorber built for Chevrolet Colorado and GMC Canyon trucks that need firmer control without sacrificing everyday ride quality. Its high-pressure gas design separates oil and gas to reduce fade and deliver quicker response under load.

Gas-a-just is KYB’s performance shock line for trucks that work, tow, or run larger tires and wheels. The KG5190 is engineered for rear suspension use on 2004-2012 Chevrolet Colorado and 2004-2011 GMC Canyon applications, including off-road suspension and recommended OE replacement setups.

Key Features

• Monotube shock design with separate gas and oil chambers for consistent damping
• Up to 25% more damping performance than original equipment shocks
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Higher gas pressure improves steering response and suspension control
• Designed specifically for Chevrolet Colorado and GMC Canyon rear applications
• Dust cover included
• Compressed length: 14.68 in; extended length: 22.95 in; stroke length: 8.27 in

Detailed Description

KYB KG5190 uses a monotube construction with an air-free hydraulic working area and a high-pressure nitrogen chamber separated by a floating piston. That layout supports fade-free operation and fast damping response when the rear suspension is carrying extra load or dealing with rough pavement. For Chevrolet Colorado and GMC Canyon owners, this rear shock absorber is a direct-fit solution for restoring control, reducing bounce, and tightening body motion.

This part cross-references Monroe Shocks & Struts 911230 for the same application. KYB KG5190 is also listed as a replacement option for Gabriel G63879.

What It Helps Address

• Excessive rear-end bounce after bumps or dips
• Reduced control when towing or hauling
• Soft or worn OE shock performance
• Suspension fade during repeated compression cycles
• Loose rear handling on Colorado and Canyon trucks with larger tires and wheels
