Coil Over Spring Rubber Orange 15

The Longacre Coil Over Spring Rubber Orange 15 is a precision polyurethane spring isolator engineered for high-performance suspension tuning on track vehicles and street machines. This medium-durometer elastomer component (SKU LON52-61015, MPN 52-61015) serves as a damping buffer between coil-over spring assemblies and their mounting points, reducing vibration transmission and protecting frame integrity during aggressive cornering, braking, and acceleration.

Manufactured from durable polyurethane rated at 15 durometer—a medium hardness that balances compliance with structural support—this rubber features a 0.75-inch height and is designed for springs with 2.5 to 2.625-inch outside diameters. The bright orange color aids in quick visual identification during assembly and maintenance. At 0.37 lbs per unit, it adds minimal unsprung weight while delivering measurable reductions in road noise and feedback harshness. Longacre coil-over rubbers are industry-standard components in road racing, autocross, and performance street applications where suspension geometry precision and vibration isolation directly impact both comfort and chassis control.

This product is ideal for builders, suspension technicians, and enthusiasts upgrading or maintaining coil-over kits on sports cars, race cars, and modified vehicles. Whether replacing worn isolators or fine-tuning suspension responsiveness, the Longacre 15-durometer rubber addresses the specific need for controlled spring isolation without excessive compliance. Individual unit pricing allows for single-replacement flexibility or bulk purchasing for fleet applications.

Coil-over spring rubbers are essential wear items in performance suspensions. Over time, polyurethane degrades from UV exposure, ozone, and repeated compression cycles. Regular inspection and timely replacement of these isolators maintain suspension geometry, reduce clunking noises, and preserve the handling characteristics that coil-over systems are engineered to deliver. The Longacre brand is recognized across drag racing, road course, and circle-track communities for consistency and durability in suspension components.
