Coil Sleeve 2.5-3.5 ID Springs

The Eibach Coil Sleeve 2.5-3.5 ID Springs (Model CS3001) are precision-engineered coil spring isolator sleeves designed to reduce noise, vibration, and harshness transmitted through your vehicle's suspension system. These sleeves are ideal for vehicle modifiers who have upgraded to a performance coil spring setup or noticed clatter in their suspension on rough roads.

Engineered for 2.5 to 3.5 inch inner diameter springs, these sleeves fit a broad range of aftermarket and OEM suspension applications. They effectively address the common problem of metal-to-metal contact between coil springs and their seats, which can degrade ride quality. The sleeves isolate spring movement and dampen vibration transfer to the chassis, preserving the spring's intended performance while eliminating unwanted noise.

Mechanics and enthusiasts tackling suspension work will benefit from these isolator sleeves, whether installing coilovers, lowering springs, or rebuilding stock suspension with performance components. The straightforward installation process allows the sleeve to slip over the coil spring, creating a protective barrier that absorbs micro-movements and enhances overall ride quality.
