Triumph Spitfire Clutch Drive Components
WHICH MODELS WERE FITTED WITH 3-RAIL TYPE GEARBOXES?
The term '3-rail' refers to the fact that this type of gearbox had 3 selector rails (in this case in a separate housing bolted to the top of the gearbox). 3-rail gearboxes were fitted to ALL Spitfire MK1, MK2, MK3 & MKIV models.
WHICH MODELS WERE FITTED WITH SINGLE-RAIL TYPE GEARBOXES?
The term 'single-rail' refers to the fact that this type of gearbox had one selector rail. Single rail gearboxes were fitted to ALL UK specification Spitfire 1500's, however, the Spitfire 1500 was introduced into the USA earlier than the UK and other European countries. This means some early USA Specification Spitfire 1500's were fitted with the 3-rail type gearbox (it is possible that some of these were re-imported into the UK).
WHICH CLUTCH KIT DO I NEED?
If you have a Spitfire MK1, MK2, MK3 or MKIV (with a standard 3 rail gearbox) you simply need to refer to the listing for your vehicle.
If you have a UK or USA specification Spitfire 1500 fitted with a single rail gearbox, you can use part no. GCK160.
If you have one of the few Spitfire 1500's fitted with a 3 rail gearbox you will need to use the individual components as follows:- Clutch Cover - GCC196, Clutch Plate GCP103 & Release Bearing GRB207.
