Prothane Coil Spring Isolator

Prothane Coil Spring Isolators are polyurethane coil spring insulators (also called coil spring seats, spring pads or spring cushions). They sit between the coil spring and its mounting seat in the suspension. They help reduce noise, vibration and metal-to-metal contact where the spring meets the spring perch.

Key Features:

• Made from Prothane polyurethane, which resists wear, cracking and deterioration better than many rubber isolators
• Helps isolate the coil spring from the chassis and suspension mounting surfaces to cut down on squeaks and road noise
• Resists road chemicals, oil, grease and moisture
• Direct-replacement design for worn, hardened or deteriorated factory isolators
• Offered in front, rear, upper and lower designs for a range of applications

Prothane polyurethane suspension parts are a popular upgrade for daily drivers, restoration projects, off-road vehicles and performance builds. Choose the individual variant that matches your application to get a durable, long-lasting replacement for the stock isolator.
