Excel-G Product Line Details

The KYB Excel-G line is calibrated to restore the vehicle’s original suspension behavior rather than change it. For drivers looking for a rear shock absorber for a Ford Ranger, Mazda B4000, Mazda B3000, or older Ford F-Series truck, Excel-G focuses on ride control, lane-change response, braking stability, and handling consistency. Part number 344079 is an OE-style replacement choice for service work where factory-like damping is the goal.

Detailed Description

KYB 344079 is a rear suspension shock absorber designed for a wide range of Ford and Mazda truck applications. It is compatible with Ford Ranger rear applications from 1989 through 2011 in the listed configurations, plus select Ford F-150, F-250, F-250 HD, and F-350 rear applications, along with Mazda B3000 and B4000 rear fitments. This part cross-references Monroe Shocks & Struts 37039 for the same application. If you are replacing a worn rear shock on a Ford Ranger or Mazda B4000, this Excel-G unit is built to restore the original damping characteristics the vehicle was designed to use.

What It Helps Address

• Excessive rear-end bounce over bumps
