Proudly Made in the
You may be wondering, "Why did someone
design an alternative head and neck restraint?" The answer is
simple: to improve on the design, comfort and safety provided by
one of the most important pieces of safety equipment you are
required to purchase. Here's a brief
summary of the improvements Necksgen has incorporated into the
design (many more are listed below):
Comfort: The REV takes
comfort to a new level... there is no frontal yoke, with no
pressure on your body or collar bone. Our low profile design gives
full range of head motion with no front or rear interference with
Lateral/Angular Impact Protection: Due to the
placement and angle of the lower tether mount, the NecksGen REV
unit offers unsurpassed lateral and angular
Clearance: The REV has a low profile design which
creates minimal interference with the seat and helmet in the
Single Tether: The single self-aligning helmet
tether creates full range of head
motion while driving and offers maximum side impact
The NecksGen REV units are designed and made in the USA, using
the latest carbon fiber composite Dupont material. Not only are
these materials lightweight, but they are extremely strong.
All NecksGen head and neck restraints have passed the mandated
SFI 38.1 testing procedures. Due to the innovative features of the
designs, the NecksGen head and neck restraints have surpassed our
expectations in test results.

Large adult units can accept 2” or 3” seat belts. Small unit
accepts 2" belts only. The wings aid in keeping your harness in
place under impact. Even in multiple impact situations where the
belts could loosen.
5. Tension Neutralizing Tether
Using a proprietary single tension-neutralizing tether (TNT),
the loads under impact are distributed through four different load
paths. This unique system offers an equal distribution of forces
under impact. This system also offers a full range of head motion
and side and angular impact protection.

ok to use these.
Q: What do I do if my helmet has
A: 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.
Q: Do I need to adjust my
A: No, the NecksGen tethers come a fixed length which has been
predetermined in testing to allow proper protection. 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.

belts be from the mounting point to my

Very good i like it
From Felix of Metairie, Louisiana on 4/17/2014.
I bought one of these Necksgen devices from WR a few months back and have been using it for DE's. It's very comfortable and works well with the shoulder harnesses of my 6-point belts. The side straps allow enough head movement to look around upcoming corners, but do seem to limit extreme lateral movements, as intended. Overall I'm very satisfied.
