With all of the head and neck restraints in use out there, we wanted to post a reminder that the manufacturers recommend replacing the tethers as follows:

R3 & Hybrid: Replace tethers every 3 years or sooner if involved in an impact or if the tethers show signs of wear.

HANS: Replace tethers every 2 years or sooner if involved in an impact or if the tethers show signs of fraying or chafing. The tethers on newer models of the Hans device now have a small tag showing the year of the tethers. If your hans is two or more years old, you should replace the tethers now or prior to your next track event.

For those of you racing with NASA, below is section 29.1.2 of the CCR for your reference.

29.1.2 Installation and Replacement
Any systems used MUST be installed and used according to the manufacturers directions. The driver is ultimately responsible for the proper installation and use of these devices. It should be noted that “webbing based” systems should be replaced at least every three years or sooner if the manufacturer specifies such. Any device that shows signs of wear or abrasions should be sent back to the manufacturer for repair or should be replaced. “Homemade” repairs are not allowed.

We strongly recommend that you consult your sanctioning body's rules so that you are in compliance for your next event.

If you have questions or need help with updating your head & neck restraint, feel free to contact us.

I will STRONGLY recommend converting to the Sliding tethers, SO much better!

Can you share why? I'm curious - haven't really looked into this previously.

Also, can the sliding tethers be used in conjunction with the quick disconnects?

Thanks much,

Rick

Is there a safety reason that I would want the sliding tethers if I like the security of the non-sliding tethers? Other then more freedom of movement when driving around the paddock.

If you go off track and you need to turn your head to see the corner workers, see traffic before getting back on the course, etc.

TRAKCAR

Just as safe and more comfortable to be able to look around etc.

When I replace mine, I am going with the sliding tethers.

Thank You for the notice. I was not aware of this. I'll be contacting you.

Is there any empirical evidence that shows that sliding tethers provide the SAME protection in an impact? I can't seem to find any and the natural hypothesis is that in an impact, sliding tethers would appear to have the ability to SLIDE/ROTATE on a z-axis thus presenting you will possible side to side injury. Just looking for some evidence.

How dare you even question Hubbard and Downing.
It they sell it, it works.....and it keeps getting better.

Do I detect sarcasm in your tone Lewis?

Rick,

Hans does not offer the QD tethers with the sliding option (yet). Possibly in the future.

Dell,

Hans has commented on the use of sliding tethers...

Every element of all of the Hans products are tested by SFI and FIA by similar standards. And they're tough. Everything has to have that approval stamp, label or tag. If the standards weren't met, the products wouldn't be certified.

Stress from an impact is transferred to the back of the HANS and to the anchors, which have the new big nut washers.

But as a factor in the dynamics of a crash, they do the job just fine. The 2 sides equalize the pressure under a G-load, regardless of the driver's head orientation, and the carriers maintain the position of the tether to help distribute the load at the strongest part of the HANS.

Hope this helps!

Yup--even though it was already perfect.
