KYB KG54336 Shock Absorber - Rear

KYB Gas-a-Just Rear Shock for Tundra

The KYB Gas-a-Just KG54336 is a rear suspension shock absorber built as an OE-style monotube replacement for the Toyota Tundra. It is designed for drivers who need firmer control, quicker response, and stable damping on trucks that work, tow, or run larger wheels and tires.

Key Features

• Monotube design separates gas and oil for consistent damping and fade-resistant operation
• Up to 25% more damping performance than original equipment shocks
• Engineered for Toyota Tundra rear suspension applications
• High-pressure nitrogen gas chamber improves steering response and control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Dust cover included for added protection
• Supports electronic safety systems by helping the suspension operate as designed

Product Details

The Gas-a-Just line is KYB’s monotube shock absorber series for OE replacement applications that need more control than a standard twin-tube design. The KG54336 uses separate working chambers: an air-free hydraulic section for responsiveness and a high-pressure nitrogen gas section with a floating piston for consistent performance. For 2000-2006 Toyota Tundra rear suspension service, this shock is a direct-fit option for restoring ride control and handling balance. This part cross-references Monroe Shocks & Struts (e.g., 37238) for the same application.

Common Problems This Part Can Address

• Excessive rear bounce or oscillation over bumps
• Reduced control when towing or carrying heavier loads
• Soft or delayed steering response from worn rear shocks
• Shock fade during repeated suspension movement
• Fluid leakage caused by worn piston rod seals

Installation Notes and Tips

Fits 2000-2006 Toyota Tundra, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify compressed length, extended length, and mount style before installation: compressed length 13.74 in., extended length 22.01 in., stroke length 8.27 in., lower mount E2(12X32), upper mount S1. The KG54336 is also listed as a rear application for the Toyota Tundra, and the part number KG54336 should be matched to the vehicle’s original suspension configuration before service.

Quality Assurance

KYB designs the Gas-a-Just line as an OE monotube replacement to restore original vehicle capability with improved damping response. The KG54336 is built with a high-pressure monotube layout and a triple chrome plated piston rod to support long-term seal life and consistent operation.
