The TRS Pro 6 Point Single Seater (part number 21F600) is built for formula and open-wheel cars. The shoulder straps are 75mm and the lap and sub straps are 50mm, matching the saloon Pro layout, but the mounting system is entirely different: bolt-in fixing plates throughout rather than snap hooks or eyebolts.
At the shoulders, 8mm bolt-in plates clamp the strap end with the bearing point sewn at 38.5cm from the adjuster. At the lap and crotch, 8mm pinch plates are used. This direct bolt-in approach is necessary in a single seater where there are no eyebolts or cage bars to clip onto; the harness fixes directly to the chassis tub.
Steel anti-creep adjusters are fitted on the shoulders. FIA 8853-2016 homologated. The 140-gram composite aircraft buckle is the same unit used across the TRS FIA range. Thumb loops on the lower shoulder straps are standard.
At £205 this is the same price as the saloon-car Magnum 4 Point, though these are for entirely different applications. If you are fitting this to an open-wheel car, confirm the chassis mounting thread and bolt size before ordering. The 8mm plates suit most formula car chassis, but check your car’s homologation sheet if you are racing to a technical specification that defines anchor hardware.
Ten webbing colours available. Black, red and blue are typically in stock. If you need a specific colour for team livery, ask ahead of ordering for current lead times.
Have you written anything about this exact product?
Yes, we have covered this exact product: Customer Question: Roll Cages For A 1976 Morgan 4/4 Two Seater, and Top 5 Recommended Single-Seater Harness Belts for 2025. Some of that comes straight from real customer questions, so you are reading answers other buyers actually needed.
How long does an FIA harness last?
Every FIA harness carries a not-valid-after date on its label, and that date is what the scrutineer checks, not the purchase date. Our guide on how long FIA harnesses last explains the labelling and when replacement is due, and buying new gets you the freshest date the maker currently produces.
What does the strap width mean for me?
This is a 3 inch shoulder to 2 inch lap harness. The shoulder width choice interacts with whether you run a HANS device, and our guide on 3 inch versus 2 inch harnesses explains which to pick and why.
Do I need a HANS-specific harness?
This is a 6-point FIA harness, which is the only type that works with a HANS device. This one is the conventional cut rather than the HANS-specific pattern, so if you run a device, compare it against the HANS-pattern versions in the range or ask us which suits your setup.
What does it mount to?
A harness needs proper anchor points: a harness bar, cage, or the car’s designed mounting points, plus a seat with the right slots, and as a 6-point it needs each point anchored correctly. Tell us the car and seat and we will confirm the mounting plan before you order.
