Just looking for everyone's opinions on the Impact Necksgen and the Impact Rev head and neck restraints. Thinking of choosing between the two. Pro's and Con's of each. Will be for running a dirt mod.
Or is there something better out there for both front and side impact.
Thanks

RBJ,
If you do a search on you tube for the Necksgen Rev Test, you will see a video showing their own test's done at CAPE labs in Indy. Notice the head location and movement during the video. If you also search Hans Device Test you will see another test done at the Cape Labs during the IMIS show in Indy in Dec. 2012. Note the head movement in that video.
I will let you and others make a choice based on each of the test videos. However, I will say that ALL 38.1 Head and Neck restraints are rated for frontal and up to 45 deg angles. Anything beyond that is not covered by any of them. For REAL side protection you need a full containment head suround seat. This along with a 38.1 Head and Neck Restraint is your best option.

Good Question. The sliding tethers have shown that they equalize and provide lower rotation loads than the old fixed style tethers used originally. With the old fixed tether if your head was turned during an impact one tether would be tight while the other side had slack. With the slider both sides will see tension and then will center the head more gradually.

Also wanted to add that I watched the videos. I find it interesting how far the helmet is away from the Hans and that there is no slack in the tethers before impact. I have not been to a test so I don't know what this means but just an observation.

Why doesn't any one turn the sled 90 degree's from straight & test side impacts ?

Can you even buy the impact Necksgen anymore? If so is it still SFI approved?
