They were cheap to manufacture for mass production and provided isolation from road noise and vibration, but rubber has a significant trade-off its relatively soft durometer (hardness) allows for significant deflection of the chassis components under load. The rubber bushings twist and deform as the suspension components rotate, causing premature wear and unpredictable handling. Rubber eventually dry rots when exposed to the elements and degrades in the presence of grease and oil.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePST\u003c\/strong\u003e perfected polyurethane with the introduction of \u003cstrong\u003ePOLYGRAPHITE\u003c\/strong\u003e - a special formula incorporating a low-friction graphite lubricant into the actual bushing material. With \u003cstrong\u003ePOLYGRAPHITE\u003c\/strong\u003e, you get the near-zero deflection performance of polyurethane with a self-lubricating bushing. As an added benefit, \u003cstrong\u003ePOLYGRAPHITE\u003c\/strong\u003e is impervious to grease, oil, weather, and other natural elements and will never dry rot. \u003cstrong\u003ePST\u003c\/strong\u003e has the most complete line of \u003cstrong\u003ePOLYGRAPHITE\u003c\/strong\u003e 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 \u003cstrong\u003ePOLYGRAPHITE\u003c\/strong\u003e \u003cstrong\u003eKits\u003c\/strong\u003e on your vehicle today.\u003c\/p\u003e","brand":"PST","offers":[{"title":"Default Title","offer_id":48033800126738,"sku":"POLY42141","price":99.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0814\/6321\/4354\/files\/POLY42141_3000_vertical02.jpg?v=1754565388","url":"https:\/\/www.kanter.com\/products\/leaf-spring-bushing-poly42141","provider":"Kanter Auto","version":"1.0","type":"link"}
