PST perfected polyurethane with the introduction of POLYGRAPHITE - a special formula incorporating a low-friction graphite lubricant into the actual bushing material. With POLYGRAPHITE, you get the near-zero deflection performance of polyurethane with a self-lubricating bushing. As an added benefit, POLYGRAPHITE is impervious to grease, oil, weather, and other natural elements and will never dry rot. PST has the most complete line of POLYGRAPHITE bushings available for your GM muscle car. Replace components as needed, or save time, money, and reap the ultimate performance benefits by installing one of our complete POLYGRAPHITE Kits on your vehicle today
