Triumph Stag Parts
Owning a Stag puts you in an interesting position. It is one of the most beautiful cars Triumph ever built, with that distinctive T-bar and Michelotti's GT lines still drawing a crowd wherever it goes. It is also a car where the ownership experience depends almost entirely on whether the previous owner maintained it properly, and specifically, whether the cooling system received the attention it needed.
The 3.0-litre V8 is unique to the Stag. Triumph designed it specifically for this car rather than adapting an existing unit, which means it shares no significant components with other engines in the range. Kept in good order, it is smooth, characterful and perfectly suited to the grand touring role the Stag was built for. Neglected, the cooling system's known thermal management challenges compound quickly. Our Triumph Stag engine components section covers rebuild kits, gaskets, pistons, timing components and service parts for the full V8, and our Triumph Stag cooling and heating range carries radiators, water pumps, thermostats and hoses for both the early Mk1 system and the revised late-Mk1 and Mk2 setup from engine number LF11277 onwards. Knowing which cooling specification your car has before ordering is essential, as the two systems use different water pump covers, hose routing and pipe arrangements that are not interchangeable.
Triumph Stag body parts remain one of the most searched categories for any restoration project. The sills, floor panels and front chassis members bear the predictable consequences of fifty-plus years of British weather, and a car that looks presentable at first glance often needs significant structural work underneath. Our Triumph Stag body parts and fittings section covers repair panels, wing assemblies, sill sections, floor pressings, door shells and all the fittings that distinguish Mk1 from Mk2 specification — a distinction that matters because many components between the two marks are not cross-compatible. Triumph Stag restoration parts for a ground-up rebuild are available here alongside individual items for targeted repairs.
The brakes on the Stag use servo-assisted front discs and rear drums, which were well-specified for a grand touring car of this weight in the early 1970s. After decades of use, master cylinder seals, calliper pistons and rear drum hardware are all regular replacement items. Our Triumph Stag brake system range covers standard replacement components alongside uprated four-piston calliper conversion kits for owners wanting more modern stopping performance without compromising the car's period character.
One of the Stag's most celebrated features is its T-bar hood system, which combines convertible versatility with a fixed roll-over structure. The hood frame, cover, seals and hardtop components all require specific parts, and Mk1 and Mk2 hood covers use different materials and attachment arrangements that must be matched correctly. Our Triumph Stag hoods and hard tops section carries complete hood assemblies, frame components and hardtop fittings for both marks. Owners looking to go further than standard will find suspension and carburation upgrades, sports exhausts and fast-road engine components in our Stag performance upgrade parts range.
