Noise and Vibration Reduction: Rear spring insulating bushing forms a buffer layer between metal components, which can buffer the contact between the spring and the support, reduce noise, road noise and severe vibration, and effectively prevent direct wear between metals, effectively protecting suspension components and extending the service life of springs and suspension components
Compatible and Adaptable: Fit for Ford F250 F350 F450 F550 Super Duty 1988-2025
Replace Part Number: Replace E8TZ-5A978-A E8TZ5A978A E8TA-5A978-AA E8TA5A978AA BC34-5A978-AA BC345A978AA
Superior Materials: Rear spring insulating bushing is made of high-quality automotive-grade rubber or polyurethane material, possessing excellent elasticity, wear resistance, and aging resistance. It will not crack or deform, maintaining durable suspension performance and reliability even under long-term loads and complex road conditions
Stable Suspension: Rear spring insulating bushings maintain the correct alignment and stable support of the leaf springs, improving the rear suspension's compressive strength and helping to restore a smooth driving experience and better handling stability
