This is a higher performance Ferrari F360/430 Front/Rear/Upper Control arm Bushing to replace Part # 184609.
It is Re-engineered for higher performance and hand built using advanced technology and materials 
Made of high quality polyurethane with a steel sleeve and mounting arm, these bushings will outperform and will have a very long service life compared to the original OEM parts. 
They will firm up the vehicle's cornering and eliminate any unconfident feel associated with the factory aging suspension.  
These bushings have a very long service life due to their floating design and proprietarily developed polyurethane compound. They will not need to be replaced as often as OEM ones, saving future labor costs and vehicle down time.  
Each bushing comes preassembled as pictured and the assembly is ready to press fit into the OEM mounting place. Once mounted, no further servicing is required.
It is highly recommended to add zerk fittings to the control arms to keep the bushings greased for even extremely longer service life.
