Delphi TD4749W Leaf Spring Shackle Bushing

Delphi TD4749W is a standard replacement leaf spring shackle bushing for rear suspension service on select Ford trucks and SUVs. Built with metal and rubber construction, it is sized for applications that call for a 0.63 in inside diameter, 1.25 in outside diameter, and 2.75 in height.

Key Features

• Metal and rubber construction for suspension service
• Standard replacement grade for OE-style fitment
• Phosphate finish
• 0.63 in inside diameter
• 1.25 in outside diameter
• 2.75 in height
• Rear forward, rear lower, rear to spring, and rear upper position coverage depending on vehicle application

Detailed Description

This Delphi leaf spring shackle bushing is engineered for rear suspension locations where the original bushing has worn, cracked, or lost its ability to isolate movement. Delphi applies dimensional and material analysis to help match OE and aftermarket requirements, and the part is tested across extreme temperature ranges and salt-spray exposure to verify durability in demanding conditions. This part cross-references Ford C5TZ5781A for the same application. Compatible With select Ford Bronco, Ford F-100, Ford F-250, and Ford F-350 rear suspension applications, including the specific positions listed in the fitment data. Delphi TD4749W is a practical choice for restoring proper leaf spring shackle function on classic Ford suspension systems.

What It Helps Fix

• Rear suspension looseness caused by worn bushings
• Clunking or squeaking from leaf spring movement
• Excessive play at the shackle or spring eye area
• Uneven rear suspension articulation from deteriorated rubber
• Loss of OE-style isolation between metal suspension components

Installation Notes and Tips

Verify the required position before installation, since this bushing is listed for rear lower, rear upper, rear to spring, and rear forward applications depending on vehicle. Confirm the inside diameter, outside diameter, and height against the original part and the vehicle application tab before ordering. For best results, inspect related shackle and spring hardware for wear during service.

Quality Assurance

Delphi uses OE-focused engineering, dimensional checks, and material analysis to support fit and function. The part is also subjected to temperature and corrosion testing to help validate performance in real-world suspension conditions.
