Made from Energy's \u003cb\u003eHyper-Flex\u003c\/b\u003e performance polyurethane, it restores proper rear suspension geometry, sharpens handling, and lasts far longer than the factory rubber it replaces.\u003c\/p\u003e\n\u003cp\u003eWorn rear bushings cause clunking over bumps, vague rear-end feel, uneven tire wear, and rear toe changes during cornering.
