Energy Suspension Hyper-Flex Red Rear Spring Upper & Lower Isolator Set for 1979-2004 Ford Mustang & Mercury Capri
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1979-2004 Ford Mustang and 1984 Mercury Capri RS.
Restore your vehicle's suspension geometry and eliminate metal-on-metal noise with the Energy Suspension Hyper-Flex Rear Spring Upper and Lower Isolator Set. Factory rubber isolators are prone to compression and dry rot, which leads to sagging ride height and increased NVH (noise, vibration, and harshness). These polyurethane replacements provide a durable foundation for your rear springs, ensuring they remain properly seated and aligned under load.
- Manufactured from signature Hyper-Flex polyurethane for maximum durability
- Resistant to oils, ozone, and road grime that destroy factory rubber
- Designed to last 3 to 10 times longer than original equipment components
- Direct-fit installation to factory chassis mounting points
- Maintains factory ride characteristics while stabilizing spring position
- Complete set includes both upper and lower isolators for the rear axle
- Manufacturer Part Number: 4.6101R
