66-79 Ford F100 Radius Arm Bushings 2WD

The 66-79 Ford F100 Radius Arm Bushings 2WD from PROTHANE are engineered to restore suspension responsiveness and eliminate excessive play in the front suspension's radius arms on classic Ford trucks. As any experienced mechanic knows, OEM rubber bushings deteriorate over decades, allowing unwanted movement that degrades handling, increases tire wear, and creates a vague, disconnected feel at the steering wheel. These polyurethane replacements are purpose-built for owners who demand precise suspension geometry and improved on-road stability without modifying the factory suspension architecture.

PROTHANE's polyurethane formulation outperforms rubber by resisting compression set and maintaining consistent stiffness across temperature ranges, critical for vehicles driven in varied climates. The black polyurethane compound provides damping characteristics that reduce impact transmission while eliminating the compliance that allows the radius arm to shift laterally under cornering loads. Radius arms are critical control members on Ford's solid front axle design; they control fore-aft and lateral movement of the axle housing. When bushings wear, bump steer increases, bump compliance worsens, and the truck exhibits wandering on highways. This kit addresses both pivot points on the 2WD suspension, restoring factory geometry and precision handling characteristics that make classic F100s more predictable and safer to drive.

Mechanics and restoration enthusiasts rebuilding 66-79 Ford F100 2WD trucks will find these bushings essential for any comprehensive suspension refresh. Installation requires only basic hand tools and a press or vise to remove worn bushings and seat new ones—a straightforward job that dramatically improves steering feel and front suspension consistency. This kit is specifically engineered for 2WD models; 4WD variants use different geometry and require separate components. Whether you're restoring a vintage daily driver or upgrading a show truck's suspension, these PROTHANE radius arm bushings deliver measurable improvements in handling response and long-term durability compared to deteriorated OEM parts.
