Eliminate Suspension Slop
BBK Polyurethane Rear Differential Bushing kit for 2005-2009 Mustang is an easy way to reduce the slop in your S197 Mustang's rear suspension. The factory bushing is a much softer rubber bushing which allows it to compress under load, which can change suspension geometry and create unpredictable handling and poor traction.
Extremely Durable Polyurethane
Polyurethane make a great choice for high performance cars because of it's stiffness but it's also much more durable than rubber, making it a great choice for a long service life. Rubber can break down pretty quickly from many environmental factors, but polyurethane is highly resistant to almost all contaminants.
