Prothane 6-1024 Rear Leaf Spring Eye and Shackle Bushing Kit

The Prothane 6-1024 is a rear leaf spring eye and shackle bushing kit engineered for Ford F-150 and F-250 trucks with 2WD and 4WD configurations. Leaf spring suspensions place extreme stress on pivot points and shackles, and factory rubber bushings are prone to softening, cracking, and deteriorating over time — leading to sloppy handling and rear axle instability.

This kit replaces worn OEM rubber bushings with premium-grade polyurethane components that resist compression, maintain their shape under load, and deliver a more precise, responsive suspension feel. All sleeves and hardware included in the kit are precision fabricated for a direct-fit installation with no modification required.

Key Features:

• Premium-grade polyurethane construction for superior durability over OEM rubber
• Resists deterioration from road salt, oils, ozone, and other atmospheric contaminants
• Precision-fabricated sleeves ensure a direct, accurate fit
• Includes Prothane Super Grease for quiet operation and proper lubrication during installation
• Helps maintain rear axle alignment and reduce steering wander
• Available in red (standard) and black
• Covered by Prothane's lifetime warranty

Upgrading to polyurethane bushings is one of the most cost-effective suspension improvements available — restoring proper geometry, eliminating bushing deflection, and extending the service life of your leaf spring system well beyond what rubber components can provide.
