KYB KG5413 Shock Absorber - Rear

KYB Gas-a-Just Rear Shock for Dodge Trucks

The KYB Gas-a-just KG5413 is a rear suspension shock absorber built for Dodge truck and SUV applications that need firmer control than a standard twin-tube design. It uses a monotube layout with separate gas and oil chambers for quick response, consistent damping, and reduced fade during demanding driving.

Gas-a-Just Performance Features

• Adds up to 25% more damping performance over original equipment shocks
• Monotube construction separates gas and oil for fade-resistant operation and immediate response
• Higher gas pressure improves steering response and suspension control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Dust cover included for added protection
• Components and valving are tuned for Dodge truck applications
• Supports vehicles that work, tow, or run larger, heavier tires and wheels

Detailed Product Overview

KYB Gas-a-just shocks are designed for drivers who want more control from the rear suspension without sacrificing everyday ride quality. The KG5413 uses an air-free hydraulic working area for responsiveness and a high-pressure nitrogen chamber with a floating piston to deliver consistent damping as conditions change. This design helps maintain stability on rough roads, under load, and during repeated suspension movement. This part cross-references Monroe Shocks & Struts (e.g., 34832) for the same application.

Fits 1974-1993 Dodge Ramcharger, rear. Fits 1975-1978 Dodge D100, rear. Fits 1977-1978 Dodge D150, rear. Fits 1975-1978 Dodge D200, rear. Fits 1975-1978 Dodge D300, rear. The KYB KG5413 is also a direct-fit rear shock option for select Dodge Ramcharger and Dodge D-series truck applications listed in the fitment data.

Common Problems This Shock Can Address

• Excessive rear-end bounce after bumps or dips
• Reduced control when towing or carrying heavier loads
• Soft or inconsistent damping from worn original shocks
• Suspension fade during repeated compression and rebound cycles
• Loose rear suspension feel on older Dodge trucks and SUVs

Installation Notes and Quality Assurance

Verify compressed length, extended length, and mount style before installation: compressed length 15 in., extended length 24.45 in., stroke length 9.45 in., with E1L/E(17.5) lower mount and E2(12.8X41.3) upper mount. This rear shock includes a dust cover and does not use an internal rebound spring or B-stop/R-stop. Follow the vehicle manufacturer’s suspension service procedures and confirm fitment against the application before installation.

KYB designs Gas-a-just shocks with monotube construction and application-specific valving for Dodge trucks, supporting consistent suspension performance and electronic safety system operation as the vehicle manufacturer intended.
