Our hard coated aluminum front engine plates solve the issue of the spring steel timing tensioner blade wearing into the soft aluminum of these lightweight plates.  The hard coating has a hardness approaching HRC70, making it exceptionally wear resistant.  The threaded holes in the plate also benefit from increased wear resistance that the hard coating provides.
This plate is specifically for Triumph TR6 USA models of the 1975-1976 which had the air pump fitted with the alternator mounted below.
