JP Triumph Roll Cages Updated For 2024

Roll cage news, August 2024

We have been through our JP roll cages for Triumph and updated every listing. Each one now has clearer information on what the cage is approved for, what comes in the kit and which car it is built for, with more colour and configuration options where JP offers them.

The Triumph range covers the Spitfire Mk2, the GT6 Mk3 and the Herald saloon, and takes in a full weld-in kit, a half cage and two DIY kits. Here is what each one is and who it suits.

  • Our JP Triumph roll cage listings have been updated for 2024
  • Cages for the Spitfire Mk2, GT6 Mk3 and Herald saloon
  • Full weld-in, half cage and DIY kit options
  • These are road and track cages, not for use in competition
  • Weld-in and DIY kits need a competent welder and fabricator

The JP Triumph Spitfire Mk2 weld-in kit

The Spitfire Mk2 kit is a full weld-in cage for Spitfire owners who want to take the car on track. It is a road and track cage, not an FIA approved one, so it suits track days and non-competitive events, not racing.

The kit includes the main roll bar, left and right A bars, roof bar, rear legs, main diagonal, harness bar, door bars, B pillar diagonals, and the mounts and foot plates.

This kit is designed to be assembled by someone with proper welding and fabrication skills. The tubes are CNC notched, marked and labelled to make assembly as straightforward as possible, but some fettling may be needed, and every tube and plate has to be cleaned and prepared before welding.

The JP Triumph GT6 Mk3 half cage

For the GT6 Mk3 there is a half cage that strengthens the rear of the car. It is a track day specification cage and a good choice for anyone who wants a solid cage on a budget.

The design is simple and keeps to the car’s classic look, with a single diagonal and a harness bar. JP builds it to follow the Motorsport UK Blue Book specifications, but it is not for use in competition. It gives far more protection in a roll than having no cage at all.

JP DIY cage kits for the Triumph Herald

For the Herald saloon we have two DIY kits from JP: a full cage and a half cage. They contain the parts you need to build your own cage. The full kit includes the main roll bar, A pillar bars, front roof bar, rear stays, diagonal, centre harness bars, single door bars, saddle clamps with nuts and bolts, and the mounting boxes and plates.

Like the Spitfire kit, these are for anyone with welding and fabrication skills. Positioning markers show where each labelled tube goes, which makes assembly easier to follow.

Choosing between them

The choice comes down to how the car is used and who is fitting the cage. A half cage keeps more of the interior and is the lighter job. A full weld-in cage gives the most protection but needs a fabricator. None of these JP cages is for competition, so if you plan to race, check your championship’s rules before buying.

Garreth’s advice is to plan the seats and harnesses with the cage, since the harness bar sets where the shoulder straps mount. Our guide to fitting a harness around a roll cage covers that, and our guide to Safety Devices cages for Triumph covers the other Triumph models.

We list JP cages for the Triumph Spitfire Mk2, GT6 Mk3 and Herald saloon.

No. They are road and track cages, suited to track days and non-competitive events.

Yes. The Spitfire Mk2 kit is weld-in and needs a competent welder and fabricator.
