Coil Over Spring Rubber Clear 10

The Coil Over Spring Rubber Clear 10 by LONGACRE is a precision polyurethane isolation component engineered for coil-over suspension systems on performance vehicles and track-focused builds. This soft-durometer spring rubber serves as a vibration dampener and load isolator between coil springs and mounting points, reducing harshness transmission to the chassis while maintaining consistent spring geometry under dynamic driving conditions. Whether you're tuning a dedicated road-race platform, autocross competitor, or street-performance machine, this component is essential for optimizing ride quality and suspension responsiveness.

Manufactured from durable polyurethane and rated at 10 durometer (medium/soft compound), the Coil Over Spring Rubber Clear 10 provides controlled compliance without sacrificing support for 2.5 to 2.625 inch diameter springs. The 0.75 inch height and compact 1.85 inch width allow seamless integration into confined coil-over perches on modern double-wishbone or MacPherson suspension architectures. Clear polyurethane construction makes it easy to visually inspect for wear, fatigue, or compression loss during routine suspension maintenance—critical for identifying when replacement is necessary to maintain consistent spring rates and suspension tuning.

Suspension builders, tuners, and track-day enthusiasts rely on LONGACRE spring rubbers to preserve the precision of their coil-over valving and spring selection. Soft durometer compounds like this 10-durometer unit excel on street applications and road-race platforms where isolation from road noise and vibration is valued alongside handling precision. Installation is straightforward—mount between the spring and perch during coil-over assembly or refresh—and the lightweight design (0.33 lbs) adds negligible unsprung mass while delivering measurable improvements in NVH reduction and chassis tuning stability.
