Questions about 4 point harnesses

[Mike445z]

I am looking at adding 4 point harnesses for the seats i just put in and was wondering if the floor mounted or roll bar mounted ones were better? Also some of the places I have looked dont specify where they mount, some say factory holes but i currently have the original lap belts. Thanks

Welcome aboard! If your gona mount them to a roll cage then you need the hoops or the bar behind the seats. Most cages dont have that bar there. If it mounts to the floor then it would need a longer strap than if it went to a cage bar id think.

Im not a fan of 4 or 5 point harnesses. Too much crap to deal with getting in and out of the seats. Might be nice if running the baja to keep you from hitting your head on the top but on a daily driver to much BS for me.

Put them in if its what you wnat to do but im guessing that after a few months youll wish you never bought them! There not as cool as you might think, even in a muscle car!

Im not exactly sure on this but i dont think you want them mounted to the cage unless the seats are mounted to the cage also. No sense in having 4 point harness if the cage or seat detach from the body. What im trying to say is if your gona get that crazy about safety then do it right and build your cage with the seat bars as well as the harness bars. Or you doing it just for looks?%)

I run four point and they work well. I used double shear tabs welded 4 on the floor for the laps and four on a crossbar behind the seats for the shoulders. I have two kids and the crossbar gets in the way as they transit the back seat through the front. Maybe should have gone with hoops instead. Also consider that hoops or a crossbar will limit your ability to recline the seat if it has that option.

Not sure if I would consider them necessary even when I am on the rocks as I usually find myself shimming out of one shoulder or the other to check out my surroundings.

Ok thanks, I want to add them because my new seats are taller and sit higher than the original seats and if I slam on the brakes or got into an accident my head would smash against the roll bar.

Why not put shoulder belts in like every other vehicle on the road??

Hey whether you want the harnesses or the typical belts-- if you want the harnesses go by this guide--

Don't use the Y style that mount to the floor-- they aren't allowed by any racing body -in the event they get used they compress the spine.

Its not a good idea or safe to have the sholder straps mounted to the floor.
