KYB KG5457 Shock Absorber - Rear

KYB Gas-a-just Rear Shock for Chrysler and Dodge Vans

The KYB Gas-a-just KG5457 is a rear monotube shock absorber built for Chrysler and Dodge minivan applications that need firmer control and consistent damping. It is designed for vehicles that work, tow, or run larger wheels and tires, while still maintaining a controlled ride in normal driving.

Gas-a-just Performance Line

KYB Gas-a-just shocks use a monotube design with separate gas and oil chambers for quick response and fade-resistant operation. The higher gas pressure helps improve steering response, and the triple chrome plated piston rod is engineered to reduce seal wear and fluid leakage concerns. This line is a strong OE-style performance upgrade for Chrysler Town & Country, Dodge Caravan, Dodge Grand Caravan, and Plymouth Voyager rear suspension applications.

• Adds up to 25% more damping performance over original equipment shocks
• High-pressure monotube design separates gas and oil for consistent response
• Built for Chrysler and Dodge minivan rear suspension tuning
• Supports vehicles used for towing, hauling, and heavier wheel and tire setups
• Triple chrome plated piston rod helps reduce seal wear
• Helps maintain suspension, brake, and tire performance as engineered
