Replace deteriorated factory rubber with the Prothane 7-1706 Rear Upper Coil Spring Isolator. Over time, original equipment (OE) rubber isolators rot and flatten, resulting in metal-on-metal contact, unwanted suspension noise, and a sagging rear ride height. These red polyurethane isolators are engineered to provide a firm, stable seat for your rear coil springs, offering significantly greater longevity and resistance to deformation than standard rubber.

• Enhanced Durability: High-performance polyurethane construction resists road salts, oils, and chemical contaminants that cause rubber to fail.
• Maintain Geometry: Helps preserve proper spring alignment and ride height by providing a consistent, non-compressible interface between the spring and the chassis.
• Noise Reduction: Effectively isolates the spring from the frame to reduce vibration and harshness while maintaining a precise fit.
• Manufacturer Part Number: 7-1706
• Position: Rear Upper
• Finish: Red Polyurethane
