Prothane 6-1218 Front Track Bar Bushing Kit Super Duty Polyurethane

The Prothane 6-1218 is a front track bar bushing kit engineered as a high-performance polyurethane upgrade over the factory rubber bushings on 4WD Ford F-250 and F-350 Super Duty trucks. Designed to address the notorious front-end wander and steering slop common on worn solid-axle Super Duty suspensions, these bushings restore precise axle location and sharpen steering response.

The track bar (also known as a panhard rod) is a critical component on solid front axle vehicles, responsible for keeping the front axle centered under the truck and controlling lateral movement during cornering and heavy loading. When the OE rubber bushings wear out, excess play develops — leading to sloppy steering, wander, and in some cases front-end shimmy. The Prothane 6-1218 eliminates that slop with durable polyurethane construction that holds its shape under pressure, heat, and corrosion where rubber cannot.

Key Features:

• Made from high-performance polyurethane — significantly more durable than OE rubber
• Designed for 21.5mm track bar bolt diameter — verify your bolt size before ordering
• Available in red or black to suit your preference
• Reduces front-end wander and lateral axle movement on solid-axle 4WD trucks
• Resists oil, road chemicals, UV exposure, and extreme temperatures
• Direct replacement for OE bushings — no modifications required
• Backed by Prothane's lifetime warranty against defects in materials and workmanship

Prothane polyurethane suspension bushings are a proven upgrade for heavy-duty and high-stress applications. The 6-1218 kit is a straightforward bolt-in replacement that tightens up the front suspension and restores confidence behind the wheel of your Super Duty.
