KYB KG5786 Shock Absorber - Front

KYB Gas-a-just Front Shock for Ram Trucks

The KYB Gas-a-just KG5786 is a front suspension shock absorber built for Dodge Ram trucks that need firmer control and quicker response than a standard twin-tube design. It uses a monotube layout with separate gas and oil chambers to reduce fade and maintain consistent damping during everyday driving, towing, and heavier-duty use.

Key Features

• Monotube shock design with separate gas and oil chambers for fade-resistant operation
• Up to 25% more damping performance than original equipment shocks
• Higher gas pressure for faster steering response and improved control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Valving and components engineered for Dodge Ram truck applications
• Supports vehicles that work, tow, or run larger, heavier tires and wheels
• R-stop rebound control feature included

Product Details

The KYB Gas-a-just line is designed for drivers who want more responsive suspension control without giving up normal ride comfort. The KG5786 uses a high-pressure monotube construction with an air-free hydraulic working area and a separate nitrogen gas chamber, allowing the shock to react quickly when load, road input, or steering demand increases. For 2003-2009 Dodge Ram 2500 front, 2003-2009 Dodge Ram 3500 front, and 2006-2008 Dodge Ram 1500 front applications, this design helps maintain consistent damping under demanding conditions. This part number, KG5786, is a direct-fit suspension shock absorber for the front position on those Ram truck platforms. This part cross-references Monroe Shocks & Struts 911221 for the same application.

What It Helps Address

• Excessive front-end bounce over bumps and uneven pavement
• Reduced steering response from worn or weak shocks
• Shock fade during towing or heavier load conditions
• Fluid leakage caused by seal wear on aging dampers
• Loss of suspension control with larger tires and wheels

Installation Notes and Tips

Compatible With 2003-2009 Dodge Ram 2500, front; 2003-2009 Dodge Ram 3500, front; and 2006-2008 Dodge Ram 1500, front.
