Rear Spring Bracket Insulator Inserts for Ford F-350 E8TZ-5A978-A, Set of 2

Rear spring bracket insulator inserts for Ford F-350

This two-piece set provides replacement rear spring insulator inserts for Ford F-350 applications using reference E8TZ-5A978-A. Each black rubber insert has a curved channel that wraps around the matching metal bracket contact surface. The set contains two inserts; check how many positions need replacement on your vehicle before ordering.

Profile and comparison dimensions

The inserts have a smooth outer face and turned edges around the open channel. Compare the channel shape and edge profile with the removed liner, as well as the bracket it fits over. The product diagram labels the two outside dimensions as approximately 1.8 inches across the channel profile and 1.65 inches along the channel. These are overall comparison dimensions, not measurements of the inner opening.

Application check

Ford F-350 rear spring bracket; confirm the E8TZ-5A978-A application and chassis configuration

Confirm the frame and bracket

Ford identifies E8TZ5A978A for a narrow-frame chassis-cab application. Confirm the part number through your VIN and rear suspension parts diagram, especially when comparing a chassis cab with a pickup. An F-350 badge or model year alone does not establish the correct bracket and liner.

Only the two rubber inserts are supplied. Inspect the metal bracket and its contact surface for damage when replacing a worn or missing liner, and follow the service procedure for your exact suspension. Brackets, spring assemblies and mounting fasteners are not included.
