Only a few visible changes occured on the Triumph TR4 during production period. Some details help to spot the differences between a 1961 TR4 and a later TR4 A. But to know if a TR4A is equipped with a solid rear axle or independant rear suspension, you will have to crawl under the car, unless there is an IRS badge on the bootlid.

Triumph TR4 A AND TR4A IRS

From 1965, rear end is modified to accomodate the independant suspension. Therefore, cars exported to North America keep the solid rear axle (TR4 A). On the other marketsla the TR4A is known as A IRS (IRS : Independant Rear Suspension).

See how the Triumphs TR4A and A IRS change from the earlier TR4 :

- new front grille : parking lamps deletion,
- new smaller front over-riders,
- side mouldings added on doors and front wings. Moulding ends on the front fenders are completed with nice finishers where parking lamps and side repeaters are located.
