KYB KG5447 Shock Absorber - Rear

KYB Gas-a-just Rear Shock for Nissan 720

The KYB Gas-a-just KG5447 is a monotube suspension shock absorber built for rear applications on the 1980-1986 Nissan 720. It is designed for drivers who want firmer control, quicker response, and consistent damping in a truck that works, tows, or carries heavier wheels and tires.

Gas-a-just is KYB’s performance-oriented shock line, using a monotube layout with separate gas and oil chambers for stable operation and immediate damping response. For Nissan 720 rear suspension service, KG5447 provides a direct-fit solution focused on control, steering response, and reduced fade under repeated use.

Key Features

• Fits 1980-1986 Nissan 720, rear
• Monotube design separates gas and oil for fade-resistant operation
• Up to 25% more damping performance than original equipment shocks
• Built with valving and components tailored for Nissan truck applications
• High-pressure nitrogen gas helps deliver quick response during load changes
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Dust cover included
• Part number: KG5447

Detailed Description

KYB KG5447 is engineered for the rear suspension of the Nissan 720 and is part of the Gas-a-just line, which uses a high-pressure monotube construction instead of a traditional twin-tube layout. That design keeps the hydraulic working area responsive while the gas chamber supports consistent damping when the suspension is working harder. The result is more controlled ride behavior on a truck used for hauling, towing, or running larger tires and wheels. The KG5447 also helps improve steering response by maintaining higher gas pressure and stable shock performance over repeated suspension movement.

Cross-reference part numbers include Monroe Shocks & Struts 31162 and Gabriel G63491 for the same application. If you are replacing worn rear shocks on a Nissan 720, KG5447 is a direct-fit option to restore suspension control and reduce excessive bounce.

What It Helps Solve

• Excessive rear-end bounce after bumps or dips
• Reduced control when carrying cargo or towing
• Shock fade during repeated suspension movement
• Loose or delayed steering response from worn rear damping
• Fluid leakage related to worn piston rod seals

Installation Notes and Tips

Fits 1980-1986 Nissan 720, rear. Verify compressed length, extended length, and mount style before installation: compressed length 11.81 in., extended length 19.09 in., stroke length 7.28 in., lower mount type S1, upper mount type E1. Inspect surrounding suspension bushings and mounting points during replacement, and confirm the shock is oriented correctly for the rear position.

Quality Assurance

KYB designs the Gas-a-just line around monotube performance and durable sealing components for consistent damping control. The KG5447 uses a high-pressure design with a triple chrome plated piston rod to support long-term operation in demanding truck use.
