Colsibro® B Range early valve guides (1959-72), 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 Tr6, T110 and T120

• Manufactured in Coventry, UK

Please note, price is per guide

Guides are available in standard diameter 0.5015"/0.5020" and oversized diameters +0.002" and +0.005"
