Product Details

KYB Mount Components focuses on suspension support parts that help maintain proper ride quality and noise control. The SM5418 coil spring insulator is designed for the front lower position on Chevrolet Cavalier and Pontiac Sunfire models, helping isolate the spring from the body or suspension seat so the system operates more quietly and consistently. For drivers searching for a front lower coil spring insulator for 1995-2005 Chevrolet Cavalier or 1995-2005 Pontiac Sunfire, this part provides a direct OE-style replacement solution.

Part number SM5418 is a practical choice when the original insulator has hardened, cracked, or compressed over time. Replacing the worn component can help restore suspension isolation and reduce unwanted contact noise in the spring assembly.

What It Helps Fix

• Squeaks from aged spring insulators
• Rattles caused by worn suspension mounting surfaces
• Vibration noise transmitted through the front lower spring seat
• Harshness from hardened or deteriorated insulator material
• Loss of OE-style suspension isolation on Cavalier and Sunfire front lower applications

Installation Notes and Tips

Install the SM5418 in the front lower suspension position only where listed fitment applies. Inspect the spring seat, surrounding mounting surfaces, and adjacent suspension components for wear before reassembly. Proper alignment of the insulator with the spring and seat is important for correct noise isolation and fit.

Quality Assurance

KYB designs Mount Components as OE-quality replacement parts for specific applications, with a focus on fit, durability, and suspension noise control. The SM5418 reflects KYB’s reputation for producing suspension components that meet the demands of original-equipment-style service.
