KYB KG4034 Shock Absorber - Rear

KYB Gas-a-just Rear Shock Absorber

The KYB Gas-a-just KG4034 is a monotube suspension shock absorber built for rear applications that need firmer control and consistent response. It is engineered for Mitsubishi Montero, Mitsubishi Montero Sport, and Dodge Raider fitments, with performance-focused valving for trucks and vehicles carrying larger tires and wheels.

Gas-a-just Product Line

KYB Gas-a-just shocks use a monotube design with separate hydraulic and high-pressure gas chambers. That layout helps maintain fade-free operation, improves steering response, and adds damping performance when the suspension is working harder than stock.

Key Features

• Adds up to 25% more damping performance over original equipment shocks
• Monotube construction separates gas and oil for consistent response
• High-pressure nitrogen gas helps reduce fade from aeration
• Triple chrome plated piston rod helps reduce seal wear
• Valving and components are tuned for truck applications
• Dust cover included
• Rear shock absorber application

Detailed Description

Part number KG4034 is designed for drivers who want more controlled rear suspension behavior without changing the vehicle’s basic ride layout. The KYB Gas-a-just design uses an air-free hydraulic working area for responsiveness and a separate gas chamber with a floating piston to maintain pressure and consistency. For Mitsubishi Montero rear shock absorber replacement and Mitsubishi Montero Sport rear shock absorber service, this design supports stable handling during normal driving and added damping when the vehicle is loaded or working harder. It also cross-references Monroe Shocks & Struts 31094 for the same application.

Fitment includes 1997-1999 Mitsubishi Montero Sport, rear; 1987-1989 Dodge Raider, rear; and 1983-1989 Mitsubishi Montero, rear. The KG4034 is a direct-fit suspension shock absorber for these rear positions and is built to match the demands of trucks and utility vehicles.

What It Helps Address

• Excessive rear bounce after bumps or dips
• Reduced control when towing or carrying heavier loads
• Soft or inconsistent rear damping from worn shocks
• Steering response that feels delayed due to suspension wear
• Fade caused by heat and aeration in the shock body
