3" vs 2" seat belts... surprising information on that

@BillyBob- I meant no offense to you personally with my comments above, I'm guessing you didn't take them that way but if so they were not intended to be personal slights.

The human body can only handle a certain amount of acceleration and deceleration and there's ways to protect it and many ways to put it in jeopardy.
Earnhardt Sr. was killed at what amounted to a 30 mph impact (he was going ~190, but far more importantly he hit the wall at an angle so the G load at impact was akin to a 30 mph hit. It was the crappy angle he wasn't protected for, which was all it took to snuff his flame).
Dale's death was a huge trigger for us in the racing community to learn far more about G-load limits and vastly more importantly to educate drivers and chassis builders about just how important these little details are. We've come a long way since that day in Daytona. Let's not devolve back from that, even in a TJ on a goat trail somewhere.
 
Jerry what would be the best 5 point harness to run in a TJ with vPRP seats?
I don't know what the "best" is, I run an RJS Racing Equipment harness in mine and Crow Enterprises is another great brand. Also, for my needs I chose to run a 4-pt, not a 5-pt.

Apparently it isn't so freaking simple to some of us because your comment about how the shoulder belt MUST be higher than the shoulders is 100% dead wrong. That's how you break necks and squirt the drivers remains outside the containment envelope of the harness system.
This is the (edited) simplified drawing I've always used to show what's recommended.

The consummate 4x4 oriented webpage most refer to for safety harness information is at https://www.pirate4x4.com/tech/billavista/Harnesses/ which is what I referred to for setting up my 4-pt. harness.

And Part 2 at https://www.pirate4x4.com/tech/billavista/Harness_install/ is how to install and set things up.

That's where I first obtained the below diagram. Edit: Which I see that BillaVista has added considerable information on the below subject. The shoulder harness mounting recommendation is now 0 degrees above to 10 degrees below. I'm going to

This is a new drawing. I edited BillaVista's drawing with just the standard 0 degree shoulder harness mount and added his -10 degree maximum recommended lower angle mount.

"Best" is Hooker Harness, https://www.hookerharness.com/ but I'm thinking that is certainly overkill. Then again if one is tumbling down the hill after slipping off the side of the switchbacks at Black Bear it surely wouldn't be overkill.


On mounting, exact standards vary slightly (depending on seat angle, use of a HANs or not, etc) but I've never seen any professional recommend anything over/above the shoulders, it is always 0-20 degrees below.
