Engine Top End
VERNIER STEEL CAMSHAFT SPROCKET
Light weight steel billet sprocket giving you the opportunity of adjusting the cam timing accurately with no fear of the timing slipping once set.
COLISBRO-BRONZE VALVE GUIDES
These are essential in all racing engines and engines converted to lead-free fuel. They are specially manufactured for us to the same standards as used by F1.
VALVE SPRING SHIMS
We have had these made specifically so that the race engines and badly worn road engines can have all the valve springs shimmed to the correct length. We have two sizes of bore diameter available to suit valve guides with or without circlips.
TUBULAR PUSH RODS
Made from chrome-moly tube these are very strong and are normally supplied to the original length. These can be made to a specific length if required.
HEAVY DUTY CYLINDER HEAD WASHERS
A must when using an aluminium head, although also recommended for iron heads as well.
