Isolation of Vibration and Noise: Rear spring insulating bushing acts as a buffer pad between the leaf spring and the mounting base, effectively preventing direct metal-to-metal contact, reducing vibration transmission, and lowering squeaking, abnormal noise and road noise generated by the suspension during driving
Durable Material: Rear spring insulating bushing is made of high-quality automotive-grade rubber or polyurethane material, which has excellent elasticity, wear resistance and anti-aging properties. It can remain stable under long-term heavy load and complex road conditions and is not easy to crack or deform
Improved Stability and Comfort: Maintains proper alignment and stable support of the leaf springs, improves rear suspension stress distribution, reduces bumps and impacts, and helps restore a smooth driving experience and better handling stability
Recommended Replacement: Suitable for situations where there are abnormal noises, increased vibrations, leaf spring sagging, or aging of the original vehicle's spacers at the rear end. It can quickly resolve common problems such as noise and wear, and is a replacement part for solving suspension issues
