Triumph TR3A

About the Triumph TR3A

In 1957 the TR3 was updated with various changes including a full width radiator grille and this facelifted model was commonly referred to as the Triumph "TR3A". However the cars were not badged as such and the "TR3A" name was not used officially,as is evident from contemporary sales brochures. The "TR3A" was built between 1957 and 1962.[16]


Although the facelifted TR3 is often referred to as the TR3A, it is badged as "Triumph TR3"
The "TR3A" was a minor update from the TR3. The updates included the new wide front grill, exterior door handles, lockable boot handle and came with a full tool kit as standard (this was an option on the TR3). The total production run of the "TR3A" was 58,236. This makes it the third best-selling TR after the TR6 and TR7. The TR3A was so successful that the original panel moulds eventually wore out and had to be replaced. In 1959 a slightly modified version came out that had raised stampings under the bonnet and boot hinges and under the door handles, as well as a redesigned rear floor section. In addition, the windscreen was attached with bolts rather than the Dzus connectors used on the early "A" models. It is estimated that only 9,500 of the original 58,000 built survive today.

The Triumph TR3 is the first production car to include standard disc brakes, which were continued on the "TR3A" facelift. The car was known for its superior braking ability, making it an autocross favorite.
