Westar ST-4916 Front Upper Coil Spring Seat & Isolator

The Westar ST-4916 is a front upper coil spring seat and isolator designed to provide critical cushioning and support in your vehicle's suspension system. This protective component fits between the top of the coil spring and its mounting surface, serving as both a spring seat and noise-dampening isolator.

Key Features:

• Constructed from durable rubber material designed to absorb shocks and vibrations from the road surface
• Helps distribute vehicle load evenly across the spring and mounting points
• Prevents metal-on-metal contact between the coil spring and suspension components
• Reduces noise, vibration, and harshness (NVH) for improved ride quality
• Extends the lifespan of coil springs by reducing wear and tear
• Front upper position application
• Manufactured to meet or exceed OEM specifications for quality, fit, and function

Over time, original spring seats and isolators can wear out, compress, or deteriorate, allowing the coil spring to contact metal surfaces directly. This creates annoying squeaks and rattles while accelerating suspension component wear. The Westar ST-4916 restores proper suspension function and quiet operation, making it an essential replacement part for maintaining your vehicle's ride comfort and handling characteristics.
