Delphi TC5778 Suspension Stabilizer Bar Link - Front

Front Suspension Stabilizer Bar Link

Delphi TC5778 is a front suspension stabilizer bar link built as a standard replacement for select Ford F-150 applications. It uses ball joint ends, a steel housing, and a dust boot to support consistent sway bar connection and steering response on the front suspension.

Compatible with 2004 Ford F-150, front and 2005 Ford F-150, front to 11/28/2004, this Delphi stabilizer link is engineered with OE-focused dimensional and material analysis for fit and function. Delphi TC5778 is a direct-fit option for drivers replacing worn front sway bar end link hardware on the Ford F-150.

Key Features

• Front suspension stabilizer bar link for select Ford F-150 models
• Ball joint ends at both connection points
• Steel housing with plastic bearing material
• Dust boot included for joint protection
• Standard replacement part with locking nuts included
• Non-greaseable design
• Part number: TC5778

Detailed Description

Delphi TC5778 is designed for the front suspension and measures 188.0 mm (7.402 in) in length, with a 45.0 mm (1.772 in) width and 100.0 mm (3.937 in) height. It features a 14 mm bolt thread diameter, 10 mm wrench size, and a 41.0 mm (1.614 in) bolt length. The link uses ball joint ends on both sides, a steel housing, and a dust boot, while omitting bushings, washers, bolts, and grease fittings. Delphi applies OE-level dimensional and material analysis to help maintain proper compatibility with the original application. This part cross-references MOOG Chassis Products K80279 for the same application.

What It Helps Address

• Front-end clunking or rattling from a worn stabilizer link
• Excessive sway bar play at the front suspension
• Loose or inconsistent steering feel over bumps
• Noise caused by deteriorated ball joint link components
• Inspection failures related to worn suspension linkage

Installation Notes and Tips

Verify front-position fitment before installation on the Ford F-150. Confirm bolt thread diameter, wrench size, and overall link length against the removed part to ensure proper match. Inspect adjacent sway bar and suspension components for wear before completing the repair. Delphi TC5778 is a direct replacement for the listed front applications and should be installed according to factory service procedures.

Quality Assurance

Delphi subjects its OE-based steering and suspension parts to extreme temperature and corrosion testing, including exposure below -40 degrees C, above 120 degrees C, and extended salt spray testing. That validation supports the durability expectations for TC5778 in everyday front suspension service.
