Dorman 540-902 Coil Spring Insulator - Front Lower
Dorman 540-902 Coil Spring Insulator
Dorman 540-902 is a direct replacement coil spring insulator for specific Ford E-Series front lower applications. Built from rubber elastomer material in a round black design, it helps restore the interface between the coil spring and its mounting point on Ford E-150, E-250, and E-350 models.
Key Features
- Precision-engineered replacement for the original equipment insulator
- Rubber elastomer construction for suspension isolation
- Round black design with mounting hole attachment
- Specific fit for front lower suspension applications
- Dimensions: 97 mm length, 97 mm width, 57 mm outside diameter, 52 mm inside diameter, 5 mm thickness
- Cross-references Delphi TD4648W and MOOG Chassis Products K160043 for the same application
Detailed Description
This coil spring insulator is made for Ford E-Series front lower suspension service where the original insulator has worn, compressed, or deteriorated. Dorman 540-902 is a specific-fit replacement for 1988-2022 Ford E-350 Super Duty, 2002-2014 Ford E-150, 2003-2014 Ford E-250, and related E-Series van and club wagon applications listed in the fitment data. It is also a practical search match for Ford E-150 Econoline, Ford E-250 Econoline, and Ford E-350 Econoline front lower suspension repair.
As a rubber coil spring insulator, this part helps maintain proper spring seating and reduces direct contact between suspension components. The Dorman 540-902 part number is commonly searched by owners and technicians servicing Ford E-Series front lower coil spring locations.
What It Helps Address
- Noise from worn or cracked coil spring insulation
- Metal-to-metal contact at the spring seat
- Uneven spring support caused by deteriorated rubber
- Suspension vibration transferred through the front lower spring area
- Loss of original spring isolation on Ford E-150, E-250, and E-350 front lower applications
Installation Notes and Tips
Verify the vehicle’s year, model, and front lower suspension position before ordering. Inspect the spring seat and surrounding hardware for wear, corrosion, or damage before installing the new insulator. Because mounting hardware is not included, reuse or replace related components as needed during service. Confirm the insulator orientation and seating surface match the original OE layout on the vehicle.
Quality Assurance
Dorman states this coil spring insulator is precision-engineered and rigorously tested to serve as a reliable OE-style replacement on specific vehicles. The Dorman 540-902 part number is built for direct replacement use in the listed Ford E-Series front lower applications.
