Prothane 7-1704 Rear Upper Mono Leaf Spring Pad Kit Red Polyurethane

The Prothane 7-1704 is a rear upper mono leaf spring pad kit crafted from high-performance polyurethane — a direct upgrade over inferior OEM rubber pads that are prone to cracking, rotting, and premature wear. Designed specifically for GM applications, this kit keeps your leaf springs properly seated and aligned while reducing unwanted noise and vibration.

Prothane's polyurethane formulation outperforms factory rubber by resisting compression set, oil, and harsh environmental conditions, delivering longer-lasting performance and improved chassis feel. This kit is an essential component when rebuilding the rear suspension or replacing worn leaf springs.

Key Features:

• High-performance polyurethane construction — superior to OEM rubber
• Rear upper position, mono leaf spring application
• Reduces noise, vibration, and harshness (NVH) at the spring-to-perch interface
• Keeps leaf springs correctly aligned in the spring perch
• Available in red or black to match your build
• Sold as a 2-piece kit (upper position)
• Backed by Prothane's lifetime warranty against defects in materials and workmanship

A must-have addition to any GM suspension rebuild, the Prothane 7-1704 provides the durability and performance that classic GM owners demand.
