Spring Insulators

A suspension insulator is a small rubber, neoprene, or foam component placed between a coil spring and the vehicle's frame or mounting perch, cushioning metal-to-metal contact and absorbing vibration as the spring compresses and extends. This suspension type insulator helps reduce road noise, prevent squeaking, and protect both the spring and surrounding mounting surfaces from wear caused by direct contact. Insulators are common on both factory and aftermarket coil spring setups, including those used with shock and spring kits, since even a properly matched spring assembly can develop noise or vibration over time without adequate cushioning, a consideration discussed further in our guide to shock and spring kits. Replacing worn or missing insulators is a straightforward way to address clunking or rattling noises traced back to the spring perch area.
