KYB KG5403 Suspension Shock Absorber - Front

KYB Gas-a-Just Front Shock for Dodge Vans

The KYB Gas-a-just KG5403 is a front suspension shock absorber built for Dodge and Plymouth vans and trucks that need firmer control than a standard twin-tube design. It uses a monotube layout with separate gas and oil chambers for quick response, consistent damping, and reduced fade during repeated suspension movement.

Gas-a-Just Performance Line

KYB’s Gas-a-just line is aimed at vehicles that work harder than average, including Dodge Ram 1500 Van, Ram 2500 Van, and Ram 3500 Van applications. The higher gas pressure and monotube construction help maintain steering response and suspension control on vehicles with heavier loads, towing demands, or larger wheels and tires.

• Adds up to 25% more damping performance over original equipment shocks
• Monotube design separates gas and oil for fade-free operation and instant response
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Higher gas pressure improves steering response
• Valving and components are tuned for Dodge truck applications
• Supports electronic safety systems by helping the suspension operate as intended

Detailed Product Overview

KYB KG5403 is a front suspension shock absorber with an 8.9-inch compressed length, 13.43-inch extended length, and 4.53-inch stroke length. It uses an E3(61.6X87X0) lower mount and an S1 upper mount. This part cross-references Monroe Shocks & Struts (e.g., 911096) for the same application. For buyers searching for a KYB Gas-a-just KG5403 front shock for Dodge Ram 2500 Van or a KYB KG5403 shock for Dodge B250 and D150 front suspension, this part matches a wide range of Dodge and Plymouth front-end applications from 1975 through 2003.

What This Shock Helps Address

• Excessive front-end bounce after bumps or dips
• Reduced steering response from worn OE shocks
• Shock fade during repeated load or road input
• Front suspension instability on work vans and trucks
• Wear-related fluid leakage from aging shock absorbers
