Product Details

The KYB Excel-G line is engineered on KYB OE assembly lines using OE-quality components and calibration focused on restoring the vehicle’s original suspension behavior rather than changing it. For Ford F-350 rear suspension service, as well as rear applications on the Bronco, F-100, and F-150, this shock absorber supports controlled ride motion and predictable handling. This part cross-references Monroe Shocks & Struts 37037 for the same application.

Compatible With 1980-1997 Ford F-350, rear; 1980-1983 Ford Bronco, rear; 1980-1983 Ford F-100, rear; and 1980-1983 Ford F-150, rear. Part number 344078 is also listed as a KYB recommended OEM replacement shock for these applications.

What It Helps Address

• Excessive rear bounce or oscillation
• Reduced stability during lane changes and braking
• Loose or unsettled rear suspension feel
• Uneven tire contact caused by worn damping control
• Delayed handling response on Ford truck and SUV rear suspension systems

Installation Notes

Follow the manufacturer’s instructions for the specific vehicle application. Some listed Ford Bronco, F-100, and F-150 applications note replacement of the suspension strut and coil spring assembly according to manufacturer guidance. Verify rear position, mount style, and dimensions before installation: compressed length 13.19 in, extended length 22.13 in, stroke length 8.94 in, lower mount type E2(12X38), upper mount type E1.
