Prothane Rear Coil Spring Isolator for 1979-1999 Ford Mustang & Mercury Capri - Black (6-1701-BL)
$40.70
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1979-1999 Ford Mustang and Mercury Capri models, including GT, LX, SVO, and SVT Cobra.
Standard factory rubber coil spring isolators are prone to rotting, cracking, and compression over time. This deterioration leads to unwanted metal-on-metal contact, increased road noise, and uneven ride height. The Prothane 6-1701-BL Rear Coil Spring Isolator is engineered to replace these worn components with a high-performance polyurethane alternative that maintains its shape and integrity under heavy suspension loads.
Constructed from Prothane’s signature polyurethane, these isolators provide a durable seat for the rear coil springs, effectively dampening vibration and preventing spring-to-chassis noise. Unlike rubber, this material is resistant to road salts, oils, and environmental contaminants, ensuring long-term suspension performance on both street and track applications.
- Replaces soft, worn-out factory rubber isolators
- Restores proper spring seating and helps maintain ride height
- Durable polyurethane construction resists compression and chemical degradation
- Black finish for a clean, OE-style appearance
- Manufacturer Part Number: 6-1701-BL
