This is a Lower Control Arm (A-Arm) Bushing Set (8) made in polyurethane for a Austin Healey Sprite and MG Midget. The bushings also have graphite impregnated in them for long life and self lubrication. Polyurethane bushes are the best compromise between standard rubber bushes and nylatron for daily driven street cars. They give improved suspension feel with greater wear resistance compared to their rubber equivalents and without the transmission of road noise and vibration suffered when fitting Nylatron style bushings.
