Give your car a responsiveness you can truly feel with the Dinan Monoball Kit. This kit provides an unrivaled responsiveness by replacing the rubber bushings in the thrust arms with precision ball joints and machined aluminum housings. Deflection is inherent in the stock rubber brushings; with this kit, that element is eliminated to improve performance. Even better, the quietest bearings on the market are virtually noise free, so you can live with them everyday. To make them even more of a cut above the rest, these are the only bearings on the market that are sealed using a rubber boot to keep out dirt and road grime, which stops them from wearing out prematurely.
