How many years is an FIA Approved harness valid for?

FIA harnesses are valid for 5 years plus the year of manufacture. For example, if you buy a 2018 manufactured harness it will be valid until 31st December 2023. The "Not Valid After" FIA label is attached to each part of the harness and can be found near the aircraft release buckle (camlock).


When should I replace my harness?

TRS recommend that harnesses should be replaced following a severe or moderate impact. This is because the strength and integrity of the webbing (and components) can be stretched in the advent of a crash.


Can saloon harnesses be wrapped around the roll bar?

Yes. TRS saloon harnesses can be wrapped around the rollcage.


What is a HANS device and an FHR?


HANS stands for Head and Neck Support.
FHR stands for Frontal Head Restraint.

HANS was the first motorsport company to pioneer a Frontal Head Restraint for racing drivers and they called their FHR a "HANS device". The expression "HANS device" stuck, and soon became the accepted trade name for FHR's in the motorsport world, even though what is being described is really an FHR.


Why is there an FIA hologram on FIA approved harnesses?

As of 1st January 2013, the FIA introduced a new FIA hologram label for all competition harnesses. TRS endorse the FIA's fight against counterfeit safety products and support the FIA's introduction of a uniquely numbered FIA hologram sticker sewn to the left-hand shoulder strap of every FIA harness. All TRS FIA approved harnesses manufactured since 2013 have the FIA hologram.
