Product Details

The Excel-G line is built for drivers who want the suspension to perform as the vehicle manufacturer intended. KYB 344073 uses a twin-tube, nitrogen gas-charged design with OE-quality construction to help maintain consistent damping over a wide range of road conditions. The part is engineered for rear suspension service on 1975-2003 Dodge and Plymouth vans, including applications such as Dodge B100, B200, B300, B150, B250, B350, Ram 1500 Van, Ram 2500 Van, Ram 3500 Van, and Plymouth PB150, PB250, and PB350. This part cross-references Monroe Shocks & Struts (e.g., 37091) for the same application.

What It Helps Address

• Excessive bouncing after bumps
• Loose or unstable rear suspension feel
