The REV X Carbon is NecksGen's newest style of head and neck restraint / frontal head restraint. Hand made from carbon fiber and lightweight materials, the new REV X adds an extra element to driver comfort. The X strap system holds the device securely in place while driving, and also helps keep it where you want it while getting in or out of the vehicle. The straps are easily adjustable to make personal fitment easy, and the double adjustable tactical buckle in front is easy to use. The vertical chest straps have some adjustment to fit men and women both easily. Quick release helmet hardware is included at no extra cost! WHAT DOES 2" or 3" MEAN? The 2" or 3" refers to the width of the accomodations for your racing harness' shoulder belts. If you use a 3" harness, a 3" device will be best. If you use a 2" harness, then you can use either the 3" OR the 2" device. "Does it work with a 3 point harness?" The REV X has been shown to reduce neck loads under impacts when tested to the NHTSA FMVSS208 standards using a 3 point belt. We always recommend you race with at least a 5 point harness for safety, but we understand that in some circumstances a 3 point is all that is available, and the REV X Carbon will add an extra layer of protection.
