KYB KG5197 Suspension Shock Absorber - Rear

KYB Gas-a-just Rear Shock for Grand Cherokee

The KYB Gas-a-just KG5197 is a rear monotube shock absorber built for 1999-2004 Jeep Grand Cherokee applications, including monotube performance upgrade use on vehicles with heavier tires and wheels. It is engineered to deliver quicker response, firmer control, and consistent damping for daily driving and load-carrying conditions.

Key Features

• Adds up to 25% more damping performance over original equipment shocks
• Monotube design separates gas and oil for fade-free operation and fast response
• High-pressure nitrogen gas chamber helps maintain ride control during demanding use
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage risk
• Valving and components are designed specifically for Jeep Grand Cherokee rear applications
• Supports vehicles that work, tow, or run larger, heavier tires and wheels
• Helps electronic safety systems operate as the vehicle manufacturer intended

Product Details

KYB Gas-a-just shocks use two working chambers: an air-free hydraulic section for control and responsiveness, and a high-pressure gas section with a floating piston for consistent ride quality. This design helps the KG5197 react quickly to steering and suspension inputs while maintaining stable damping under repeated compression and rebound cycles. The rear shock is a direct-fit suspension shock absorber for 1999-2004 Jeep Grand Cherokee models, with fitment listed for rear installation and an exception for Up Country Suspension configurations.

This part cross-references Monroe Shocks & Struts 37162 for the same application.

What It Helps Address

• Excessive rear suspension bounce after bumps or dips
• Reduced control when towing or carrying added weight
• Soft or delayed shock response from worn OE dampers
• Fade caused by heat and aeration in conventional twin-tube designs
• Steering and body control issues related to weak rear damping

Installation Notes

Fits 1999-2004 Jeep Grand Cherokee, rear. Confirm suspension configuration before ordering; this application excludes Up Country Suspension. Verify compressed length, extended length, and mount style against the original shock before installation. The KG5197 uses E2(12X36) lower and E2(12X46) upper mounts and includes a dust cover.

Quality Assurance

KYB designs the Gas-a-just line for consistent damping performance and durable seal protection in demanding suspension service. The KG5197 part number is used for direct replacement and performance-oriented rear shock service on Jeep Grand Cherokee applications.
