Energy Suspension 3-5144R Hyper-Flex Polyurethane Coil Spring Isolator Set

The Energy Suspension 3-5144R Hyper-Flex polyurethane coil spring isolator set is engineered to withstand the demanding conditions of performance suspension systems. Unlike factory rubber isolators that deteriorate over time, these polyurethane isolators resist cracking, crushing, and degradation from road chemicals, oils, and extreme temperatures.

Key Features:

• Constructed from durable Hyper-Flex polyurethane material for extended service life
• Impervious to under-car contaminants including oils, road salt, and chemicals
• Designed to handle the increased stress of lowered and performance suspensions
• Black finish for a clean, discreet appearance
• Direct replacement for worn factory rubber isolators
• Reduces noise transmission and improves ride quality

These coil spring isolators install between the coil spring and the suspension mounting point to cushion contact points, eliminate rattles, and protect both the spring and chassis. The polyurethane construction provides consistent performance throughout the life of your suspension, making them ideal for street performance vehicles, lowered applications, and enthusiast builds that demand reliability.
