Prothane 11-47059BL Rear Leaf Spring Pad Kit Black Pair

The Prothane 11-47059BL is a rear leaf spring pad kit engineered as a direct polyurethane upgrade over worn or deteriorating OEM rubber spring pads. Sold as a pair, these pads seat between the leaf spring and the axle perch or mounting plate, cushioning the spring pack and preventing metal-to-metal contact.

Prothane's polyurethane compound outperforms factory rubber in durability, shape retention, and resistance to road contaminants. Unlike rubber pads that compress, crack, and degrade over time, these polyurethane pads maintain their form for the life of the vehicle, helping to keep leaf springs properly aligned and reducing noise, vibration, and harshness (NVH) transferred through the suspension.

Key Features:

• Material: High-durometer polyurethane — more durable than OEM rubber
• Color: Black (contains a small amount of graphite to help resist squeaking)
• Position: Rear axle / leaf spring
• Quantity: Sold as a pair (2 pads)
• Fit: Direct OEM replacement — no modifications required
• Resistance: Oil, coolant, road grime, and environmental contaminants
• Warranty: Prothane Lifetime Warranty against defects in materials and workmanship

Prothane's black polyurethane formulation shares the same durometer (hardness) as their red compound, offering identical performance characteristics. These pads are a straightforward drop-in replacement during a spring swap or suspension refresh, restoring proper spring-to-axle interface and eliminating the clunking and settling associated with failed OEM pads.
