F.A.Q.

Is the defNder still available?

The defNder is no longer being manufactured.

Is my defNder still SFI approved?

Yes. Any defnder with an SFI decal, is SFI certified. The defNder is not currently listed on the SFI website because we are no longer in new production. However, any devices still in the field or at retail outlets that have SFI 38.1 stickers on them were properly tested and certified at the time. The certifications for those devices remain valid.

What do I do if my tethers are too tight and I can barely move my head?

Please refer to step 3 in the manual.

What do I do with the tool kit included with the defNder?

#1 – Helmet Hardware installation insert – this handy Tool makes it easier to install your Helmet Hardware and will prevent the Barrel Bolt from rotating while you tighten the Nut inside your helmet. Simply insert this Tool into the “slot” on the Helmet Hardware (where you would typically attach the Tether to your helmet via the Helmet Hardware). Then tighten the Nut on the inside of your helmet. Remove the Tool and insert the Tether.

#2 – Spacer for larger drivers – this is necessary ONLY if you feel that the defNder is too tight around your chest area. The spacers effectively “spread” the Stabilizer Bar. Simply remove the bolt and nut that attach the Stabilizer Bar (the black or green yoke) to the Chassis (the grey part). Insert the spacer between the Stabilizer Bar and the Chassis, then securely re-install the bolt and nut. Repeat on the opposite side of the unit.

Is the defNder approved by my sanctioning body?

Please check the rule book for your particular sanctioning body. If the rule book for your series requires a Head and Neck Restraint (HNR), it will typically specify that the HNR pass the SFI 38.1 standard; the defNder passes this stringent certification. If your series specifies another brand by name only, then contact your technical director and ask them why they are limiting your choices.

What is your return policy?

Wtihin 30 days, we will accept your return and refund your payment less shipping and a $25 re-stocking charge if your DefNder is returned in original condition, with original packaging. If you purchased through a dealer, you must return to the dealer.
