Triumph Prefix/Suffix table
This table attempts to list the many prefix and suffix letters used on
Triumph cars and units. The information is based upon information from
many Triumph parts catalogues. There are still a few gaps and, probably, a few errors
in it so I would be grateful for any feedback from anyone with more accurate
information. I have not attempted to deal with the VIN numbers that took
over from this system in 1980.
Please send any additions or ammendments to
Keith Bennett (work) or
Keith Bennett (home)
N.B. Except where shown otherwise, engine numbers normally have the suffix
'HE' for high compression or 'LE' for low compression.
