The SFI Foundation, Inc. (SFI) is a non-profit organization established to issue and administer standards for specialty/performance automotive and racing equipment.
Is the NecksGen REV an approved device for my sanctioning body?
Most racing organizations in the USA, that have recently mandated neck restraints, require an SFI approved device. NecksGen REV is an SFI approved device.
How does the NecksGen REV stand up to other restraints in the market in testing?
Amazing! The NecksGen REV has passed the SFI test with results that exceed all of our expectations!
Does the NecksGen REV offer any side protection?
Yes, the NecksGen REV incorporates lateral tethers, that offer alternative load paths in side-on impact for superior protection.
Is the NecksGen REV flame resistant?

Do I need to buy additional helmet hardware or other accessories?

Will I need to drill my helmet?
If you have a new SAH2010 helmet or a pre-drilled helmet, it is ok to use these.
What do I do if my helmet has been drilled?
The NecksGen will work using those holes! Simply install the Quick Release helmet hardware using the backing plate (washer nut). You will have to unscrew the backing plate from the helmet hardware (backing plate is screwed to the QR helmet hardware when you buy it). The backing plate goes in the inside of your helmet – between the foam and the inside of the helmet.
What if my helmet has never been drilled?
You easily drill your helmet by viewing the helmet drilling instructions.
Do I need to adjust my tethers? (REV, Original)
The NecksGen REV and Original tethers come a fixed length which has been predetermined in testing to allow proper protection for most drivers. However, all helmets are different in design and manufacture, therefore SAH2010 pre-drilled holes may be in different positions. Drivers also have different neck lengths. Some drivers may be able to move their head forward and still not feel the tension of the tethers, this is ok. In the event of an accident, the unit is held back by the seat belts, whereas the body, neck & head will move forward and away from the device. It is at this point, that the tethers will tension up to minimize neck tension. Please refer to the Tether Length page to learn how to do a tether slack test to check that the tether is the correct length for you.
If you feel that you are unsafe or uncomfortable with the length of your tethers, you can purchase a shorter or longer tether from NecksGen to accommodate your needs. Before purchasing please do a tether slack test* to measure how much slack you have in the tether while seated and belted in your racecar. Your tether should be between 1″ and 3″ of total slack. 1″ to 3″ is the safe zone, and the device begins to lose effectiveness after 4″ of slack. Do not purchase a tether that will allow more than 3″ of slack.
*The tether slack test is done by buckling into your car, looking straight ahead at the horizon, and pulling the loose/slack tether all to one side. The amount of tether that is excess is the slack. See more here.
Seats & Belts
Can I use 2” seatbelts with my NG?
Yes, 2” belts work with all NecksGen units.
Can I use 3” belts with my NG?
3″ belts work with the NecksGen REV and original devices in Large and Medium sizes. However, the small size units can only accept 2″ belts.
Can I use Padded belts with my NG?
No, ideally the seatbelt shoulder harness will be free of any obstructions that would cause the device to interfere with the belts. There should be no need for a pad on the belt because the REV has enough padding.
What should the gap between my upper belts behind the seat be?
The gap can be as close as 4″ and as wide as 8″
What angle should the seat belts be from the mounting point to my shoulders?
We recommend anywhere from zero to 10 degrees below horizontal of the highest point on the shoulders. Your shoulder belts should pull you slightly down and back as you tighten them.
Why is the NecksGen REV not adjustable?
The NecksGen REV has no frontal yoke section and therefore does not need any adjustment.
Can my seatbelts come off my shoulders while driving or during and accident?
The NecksGen REV has upper belt guides that will keep a secure belt on at all times.
Can the unit rotate while driving or during an accident?
The NecksGen REV has inner and outer belt guides designed to keep the unit in place at all times.
Does NecksGen work with my seat?
Yes, the NecksGen REV unit will work with most race seats without any modifications.
Why does the REV have a marble like look and texture to it?
The NecksGen REV unit is made from a carbon filled nylon composite. The material you see is carbon flowing throughout the structure adding an immense amount of strength.
