Colsibro® BSA valve guide, available in standard and oversized diameters:

• Our guides are manufactured in-house from Colsibro®, a high copper alloy material

• The bores are machined using a gun drill that produces a very close tolerance "burnished" bore, which helps to increase the life of the guide

• To ensure maximum concentricity both the bore and the outside diameter are fine-turned in one operation

• Fits A50 and A75 (1971 - 1973) 

• Manufactured in Coventry, UK

Please note, price is per guide
