Key Features & Benefits

• Superpro Polyurethane Compound — Resists compression, oil, ozone, and road chemicals far better than OEM rubber, extending service life significantly beyond factory bushings
• Restored Suspension Geometry — Maintains precise control arm positioning to reduce camber and toe changes under load, improving tire contact and wear patterns
• Reduced Suspension Flex — Stiffer durometer rating minimizes control arm movement during cornering and braking for sharper, more predictable handling

• Greaseable Design — Includes grease ports for ongoing lubrication, minimizing noise and maximizing bushing longevity over time
