hey guys.. i wanna get some aftermarket harness for the JK.. i like seatbelts.. but i prefer a pull tight harness.. any of yall got some simple bolt in harness that doesnt require a bunch of different things other than bolting in old stock mounting spots?

 

When you go to a harness that uses only the stock mounting points, you become dependent on the seat back to restrain your body in a collision. I think you will find the stock seat is not rated to do that.
The installation of a cross bar behind the seats would be necessary.

Then you must consider the angle at which the shoulder harness goes back from your shoulders. If it goes down from your shoulders at all, it will compress your spine in a frontal collision. Again, a cross bar, at or above shoulder level, would be necessary.

The cage in the JK is not rated to keep its shape in a roll-over like the cages in race cars. Being able to lean toward the center of the JK may be a benefit you don't want to give up.
