• Delphi OE-focused dimensional and material analysis for fitment consistency

Detailed Description

Delphi TC6439 is a rear suspension stabilizer bar link engineered for rear axle applications on 1980-1997 Ford F-150, Ford F-250, Ford F-350, and Ford Bronco models. The part number TC6439 is built as a standard replacement with rubber bushings and OE-informed sizing to help maintain the rear stabilizer bar connection on vehicles that rely on stable suspension geometry and controlled body motion. Delphi applies OE-level testing to aftermarket steering and suspension components, including exposure to extreme temperatures and salt spray, to verify material durability and dimensional consistency.

This part cross-references Monroe Shocks & Struts (e.g., DM35.480017) for the same application.

Vehicle Fitment

• Fits 1980-1996 Ford Bronco, rear.
• Fits 1980-1996 Ford F-150, rear.
• Fits 1980-1989 Ford F-250, rear.
• Fits 1980-1985 Ford F-350, rear, 13.8in Length; 133in - 155in Wheelbase; without E6 Axle(s).
• Fits 1986-1987 Ford F-350, rear, 13.8in Length; with 133in Wheelbase; without E6 Axle(s).
• Fits 1988-1997 Ford F-350, rear, 13.8in Length; 133in - 155in Wheelbase; without E6 Axle(s).

What This Part Helps Address

• Rear sway bar looseness or worn link movement
• Clunking or rattling from worn stabilizer bar hardware
• Reduced rear suspension stability during cornering
• Uneven handling feel caused by deteriorated bushings
• Fitment issues when replacing an OE-style rear stabilizer bar link

Installation Notes and Tips

Confirm rear position, wheelbase, and axle notes before ordering, especially on Ford F-350 applications with 13.8 in. length requirements and without E6 axle(s). Inspect the stabilizer bar, mounting points, and surrounding bushings for wear before installation. Verify thread diameter and sleeve dimensions against the original part to ensure proper alignment during replacement.

Quality Assurance

Delphi uses OE safety and engineering expertise in its aftermarket steering and suspension portfolio. TC6439 is tested for temperature extremes and salt-spray exposure, and Delphi’s dimensional and material analysis supports OE-style compatibility for the listed Ford applications.
