The original lower arm rubber bush with a metal insert. This fits all arms that have twin taper lower arms. Only some very early minis have the arm without the taper which takes 2 top hat rubber bushes. Priced and supplied as 1 item but two are required per arm. Fed up with having to change these bushes? we have produced an offset type which are always required when changing any of the performance suspension components, or having the geometry set up correctly on the front- These bushes made in UK are C-STR632 and will last much longer
