Prothane 6-1217 Front Track Bar Bushing Kit Super Duty Polyurethane - F250 F350

The Prothane 6-1217 is a front track bar bushing kit engineered for early-build Ford F-250 and F-350 Super Duty 4WD trucks. Designed for vehicles equipped with the original 15.5mm track bar bolt, this kit replaces worn factory rubber bushings with high-performance polyurethane to restore and improve front suspension control and steering precision.

Why Upgrade to Polyurethane?

OEM track bar bushings are made of rubber, which degrades over time under heat, pressure, and heavy-duty use. Prothane's polyurethane compound is significantly more resistant to wear, corrosion, and deformation, helping eliminate the steering wander and front-end vagueness that worn rubber bushings cause in high-mileage Super Duty trucks.

Key Features:

• High-performance polyurethane construction — outlasts OEM rubber bushings and maintains shape under load
• Available in red or black — both colors share the same durometer (hardness) and performance characteristics
• Black variant includes graphite additive to help minimize bushing squeak
• Designed for 15.5mm OE bolt — fits early-production 1999 F-250/F-350 Super Duty 4x4 trucks
• Includes pre-lube — proper greasing at installation is recommended to prevent noise
• Reduces unwanted suspension movement — improves steering response and reduces body roll during cornering
• Made in the USA
• Backed by a lifetime warranty against defects in materials and workmanship for the original purchaser

This kit is specifically designed for early-build 1999 model year Ford Super Duty trucks. Trucks manufactured after early 1999 use a larger bushing and require a different part number. Always verify your vehicle's production date before ordering.
