KYB KG6416 Suspension Shock Absorber - Rear

KYB Gas-a-just Shock Absorber KG6416

The KYB Gas-a-just KG6416 is a monotube suspension shock absorber built for trucks and other vehicles that carry load, tow, or run larger tires and wheels. It uses separate gas and oil chambers for quick response, consistent damping, and reduced fade during demanding driving.

Gas-a-just Performance Line

KYB’s Gas-a-just line is engineered with a high-pressure monotube design that reacts faster than a traditional twin-tube shock. The design helps maintain control under changing road conditions while keeping normal ride quality comfortable for everyday driving.

Key Features

• Adds up to 25% more damping performance over original equipment shocks
• Monotube construction separates gas and oil for fade-resistant operation
• High-pressure nitrogen chamber delivers instant response when load or road demand increases
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Designed for heavy-duty truck use, towing, and larger wheel and tire setups
• Supports steering response and helps electronic safety systems operate as intended
• Dust cover included

Detailed Description

KYB KG6416 is a suspension shock absorber designed to improve control without sacrificing everyday drivability. Its air-free hydraulic working chamber provides responsiveness, while the nitrogen gas chamber with a floating piston helps maintain consistent performance as conditions change. This makes the KG6416 a practical choice for truck owners who need stable damping for hauling, towing, or added unsprung weight from aftermarket wheels and tires. This part cross-references Monroe Shocks & Struts (e.g., 65453) for the same application.

Compatible With select truck applications, the KYB Gas-a-just KG6416 is a direct-fit suspension service part for drivers looking to restore damping performance and steering feel. If you are replacing worn shocks on a truck used for work or daily driving, KG6416 helps address the loss of control that often comes with age, load, and heat-related shock fade.

What It Helps Solve

• Excessive bouncing after bumps or dips
• Reduced steering response from worn shock absorbers
• Shock fade during towing or heavy-duty use
• Uneven control with larger tires and wheels
• Fluid leakage related to worn piston rod seals

Installation Notes and Tips

Verify compressed length, extended length, and mount type before installation. KG6416 uses E2(19X45) upper and lower mounts, with a compressed length of 16.77 inches, extended length of 26.61 inches, and stroke length of 9.84 inches. Confirm the vehicle’s original shock dimensions and mounting style before ordering. For best results, inspect related suspension components such as bushings, mounts, and tires during replacement.

Quality Assurance

KYB is a major OE supplier in the suspension market, and the Gas-a-just line is built around controlled damping, durable construction, and consistent response for demanding truck applications. Part number KG6416 is engineered to meet the needs of vehicles that work, tow, and carry heavier loads.
