KYB Gas-a-Just Rear Shock for Frontier and Xterra
KYB Gas-a-Just KG4026 is a rear monotube shock absorber built for drivers who want firmer control, quicker response, and consistent damping under load. It is engineered for select Nissan Frontier and Nissan Xterra applications, with additional coverage for several older Isuzu, Jeep, and Toyota rear suspension setups.
Key Features
- Monotube design separates gas and oil for fade-resistant operation and immediate response.
- Delivers up to 25% more damping performance than original equipment shocks.
- High-pressure nitrogen gas helps maintain ride control during towing, hauling, and rough-road use.
- Triple chrome plated piston rod helps reduce seal wear and fluid leakage.
- Valving and components are tuned for Nissan Frontier rear applications.
- Dust cover included for added protection.
- Compatible with electronic safety systems that rely on suspension performance staying within manufacturer targets.
Product Details
The KYB Gas-a-Just line is designed for drivers who need more control than a conventional twin-tube shock can provide. KG4026 uses two working chambers: an air-free hydraulic section for responsiveness and a separate high-pressure gas chamber with a floating piston for stable ride quality and instant damping demand. This rear shock absorber is a strong choice for Nissan Frontier and Nissan Xterra owners looking for a direct-fit suspension upgrade, and it also serves select rear applications on Isuzu, Jeep, and Toyota models. This part cross-references Monroe Shocks & Struts 911530 for the same application.
Fits 2000-2004 Nissan Frontier, rear. Fits 2000-2004 Nissan Xterra, rear. Fits 1981-1987 Isuzu Pickup, rear. Fits 1969-1987 Toyota Land Cruiser, rear. Fits 1986 Isuzu Trooper, rear. Fits 1986 Jeep Comanche, rear. Fits 1984-1985 Isuzu Trooper, rear.
Common Problems This Shock Can Address
- Excessive rear-end bounce over bumps or uneven pavement
- Reduced control when towing or carrying heavier loads
- Slow steering response caused by worn rear damping
- Shock fade during repeated suspension movement
- Oil seepage or seal wear on aging rear shocks
Installation Notes and Tips
Verify compressed length, extended length, and mount type before installation. KG4026 uses E1 upper and lower mounts, with a compressed length of 13.7 inches, extended length of 22.17 inches, and stroke length of 8.46 inches. Confirm rear suspension configuration and model-year coverage before ordering, especially on older Isuzu and Toyota applications. Replace worn shocks in pairs on the same axle to maintain balanced rear suspension behavior.
Quality Assurance
KYB is known for OE-focused suspension engineering, and the Gas-a-Just line uses a monotube design with high-pressure gas separation to maintain consistent damping performance. KG4026 is built to support stable rear suspension control on vehicles that work, tow, or run larger tires and wheels.
