Upgrade your 79-04 Ford Mustang with BBK Performance's polyurethane rear spring isolators designed specifically for the Mustang's coil spring suspension system. These isolators serve as direct replacements for the original rubber components, offering enhanced durability and resistance to the cracking and drying out that often occur over time. By installing these polypropylene isolators, you can prevent metal-to-metal contact between the springs and control arms, reducing harsh vibrations and noise during driving. This upgrade is especially beneficial when installing lowering springs, ensuring smoother handling and longer-lasting suspension components.
BBK's polyurethane isolators are made in the USA, ensuring quality craftsmanship and material integrity. Sold in pairs, each kit contains four pieces suitable for the rear suspension of your Mustang. They are engineered to withstand the stresses of daily driving while maintaining their shape and function over the years. These isolators are compatible with a wide range of 1987 through 2004 Mustang models, providing a versatile solution for enthusiasts seeking improved suspension performance.
Backed by a one-year manufacturer’s warranty, BBK Performance parts guarantee reliability and quality. An optional extended warranty offers an additional two or three years of coverage, providing peace of mind for long-term durability. Proper installation and normal use ensure the lifespan of these polyurethane isolators, making them an essential upgrade for Mustang owners looking to enhance ride quality and suspension longevity.
