Classic Alfa production. Polyurethane bush kit to fit the rear 'A' arm on all 750, 101 and 2600 Series cars with 52mm sized bushes. These bushes have the correct longer centre pin as original and are supplied with 4 metal spacers to prevent sideways movement - a rubber version of this bush with the correct dimensions has not been available for many years. Rated at 75 Shore for a mild improvement in rear axle location. Please enquire for availability if you have a very early 750 Series car with the smaller 34mm bushes.
