04-06 Ford F150 Sway Bar and End Link Bushing Kit

The 04-06 Ford F150 sway bar and end link bushing kit from PROTHANE is engineered to restore and enhance your truck's suspension geometry after years of wear. Factory rubber bushings deteriorate under load, causing excessive body roll during cornering and reducing your F150's stability during towing or hauling. This complete bushing replacement kit addresses that degradation, allowing your suspension to perform as originally designed while providing the foundation for further handling upgrades. Whether you're a weekend warrior upgrading your suspension or a mechanic restocking your shop, this kit delivers the precision fit that Ford F150 owners demand.

PROTHANE's polyurethane formulation outperforms OEM rubber by maintaining structural rigidity across temperature extremes and heavy use cycles. The sway bar bushings and end link bushings work in concert to minimize lateral chassis movement, directly controlling how the suspension transfers cornering loads through the frame. Polyurethane's resistance to oil, ozone, and UV degradation means these bushings retain their stiffness far longer than rubber equivalents, preserving your investment and suspension tuning for years. The compact 4.2 x 3.2 x 4.8 inch packaging houses all necessary components for a complete sway bar system refresh on 2004–2006 F150 models, simplifying inventory and installation logistics.

Mechanics and DIY enthusiasts working on fourth-generation F150s will appreciate the bolt-in compatibility—no welding, cutting, or custom fabrication required. Installation pairs seamlessly with stock sway bars or aftermarket bars, making it an ideal first step in suspension modernization before upgrading to larger diameter bars or upgraded control arm bushings. This kit is particularly valuable for trucks that see towing duty, where tired suspension bushings amplify trailer sway and reduce braking response confidence. Fitment is verified for model years 2004, 2005, and 2006 F150 SuperCrew, SuperCab, and Regular Cab configurations across all bed lengths.
