97-03 Ford Expedition Sway Bar Bushings 33mm

The PROTHANE 97-03 Ford Expedition Sway Bar Bushings 33mm (Part No. 6-1138) are polyurethane front sway bar bushings engineered to replace worn OEM rubber components on full-size Ford Expeditions from model years 1997 through 2003. These non-greasable bushings combine a 33mm bar diameter with a polyurethane-over-steel construction, offering superior performance characteristics for vehicles that experience sustained handling loads or off-road duty.

Polyurethane sway bar bushings maintain their stiffness and load-carrying capacity significantly longer than factory rubber bushings, which degrade under UV exposure, heat cycles, and suspension stress. The 33mm specification is matched to Ford's full-size SUV suspension geometry, ensuring proper spring rate and anti-roll characteristics without requiring suspension modifications. The non-greasable design eliminates maintenance intervals associated with greased bushings, reducing long-term service requirements. Supplied in a complete kit with cadmium-plated hardware, installation restores precise handling geometry lost to bushing wear and is compatible with standard suspension components.

This upgrade addresses a common wear point on aging Expeditions used for towing, off-road recovery, or high-mileage patrol service. Worn sway bar bushings allow excessive lateral movement during cornering, reducing tire contact patch consistency and increasing body roll. Technicians and DIY rebuilders restoring suspension geometry on 1997–2003 Expeditions will find this kit essential for maintaining OEM handling characteristics and preventing accelerated wear to adjacent suspension components like tie rods and control arm bushings.
