Energy Suspension coil spring isolator set in red fits springs with a 2.75-inch inner diameter and 4 9/16-inch outer diameter, with a 0.75-inch height. Molded from Hyper-Flex™ polyurethane, these isolators install like OEM, maintain factory ride feel, and last three to ten times longer than rubber. They help reduce spring noise, provide lasting chassis support, and offer modest ride-height control where needed.
