ACDelco 15882987 Rear Upper Coil Spring Insulator

The ACDelco 15882987 is a rear upper coil spring insulator designed to provide cushioning and isolation between the coil spring and the vehicle's frame or suspension mounting point. This genuine GM component helps reduce noise, vibration, and harshness (NVH) while protecting both the spring and the chassis from metal-to-metal contact.

Key Features:

• Engineered to OEM specifications for precise fitment and performance
• Durable rubber construction resists compression and weathering
• Reduces suspension noise and vibration transfer to the cabin
• Prevents metal-to-metal contact between spring and mounting surface
• Direct replacement for worn or deteriorated original insulators

Spring insulators are critical maintenance items that can deteriorate over time due to heat, road salt, and constant compression cycles. Replacing worn insulators restores proper suspension geometry, eliminates clunking noises, and ensures optimal ride quality. ACDelco parts meet stringent GM quality standards and provide reliable performance for GM vehicles.
