Like the rest of Daystar's extensive Polyurethane kits, Daystar Spring and Shackle Bushings are an excellent upgrade over stock rubber bushings. They allow less deflection while cornering and can help restore steering feel when used in the front of a vehicle. Like the rest of Daystar's Polyurethane products, these bushings are resistant to vehicle fluids and road grime. They also use a unique Polyurethane blend that ensures long life and consistent performance. Daystar's 30 years of experience has resulted in the widest selection of replacement bushings that you're going to find. Whether it's a vehicle restoration or an upgrade over rubber, Daystar spring and shackle bushings make a difference you can feel.
