Prothane 1-1012BL Leaf Spring Eye & Shackle Bushing Kit Black Polyurethane

The Prothane 1-1012BL Leaf Spring Eye and Shackle Bushing Kit is a premium polyurethane upgrade designed to replace worn or deteriorated OEM rubber bushings at the critical pivot points and shackle mounting locations of your leaf spring suspension. Engineered for superior durability and performance over factory rubber, this kit restores proper suspension geometry and improves overall handling and load-carrying capability.

Factory rubber bushings are prone to premature wear, road grime contamination, and eventual failure. Once OEM bushings deteriorate, leaf spring effectiveness is significantly reduced—resulting in a rough ride, diminished towing or hauling capacity, and compromised vehicle control. Prothane's high-grade polyurethane material resists road grime, oils, and environmental exposure that quickly degrade rubber, delivering a longer service life and more consistent performance.

Key Features:

• Black polyurethane construction — includes a small amount of graphite blended into the urethane compound for added protection against squeaking
• Premium-grade polyurethane — same durometer (hardness) as Prothane's red bushings, offering equivalent performance and longevity
• Includes Prothane Super Grease — specially formulated lubricant pre-packed into the bushing for quiet, smooth operation right from installation
• Precision-fabricated sleeves — machined to exact tolerances for a proper OEM-replacement fit with no modification required
• Complete kit — includes both spring eye and shackle bushings for a full bushing replacement at all leaf spring mounting points
• Backed by Prothane's Lifetime Warranty — warranted against defects in materials and workmanship for as long as the original purchaser owns the vehicle

For best results, apply the included Super Grease thoroughly to each bushing during installation to ensure quiet, long-lasting operation. Prothane's polyurethane leaf spring bushings are a proven upgrade for trucks, SUVs, and off-road vehicles running leaf spring suspension systems.
