Ideas for securing 4 point harneses

Ey guys, next spring in taking the jeep to silver lake for some dune jumping but before then I want to get some harnesses installed. Does anyone have any ideas for securing the shoulder straps behind the seats. I have crappy welding experience so welding a cross bar behind the seats at shoulder height is prettying out of the question.... Bolt in options????

Not to be a d**k but nothing about jumping a unibody rig is a good idea. Being an ex auto body tech and current mechanic I've seen unibodies tweaked and all sorts of other damage from bumping a curb wrong @15mph so jumping a unibody, even a Jeep, is a bad idea!

Needs parts?

Your okay. I am always open to advice. How about just racing at the dunes or climbing them?

Frame construction is not the issue. There are plenty of unibody rigs catching air. For example the JeepSpeed series. If you are going to be jumping this rig then of course you need a harness but before that you need to invest some serious $$$ in the suspension. And in particular progressive rate bump stops, shocks, and beefed up mounting points. Followed by a cage. And then the harness comes into the picture.

A harness is dumb without a cage......it'll just hold you in place better for getting crushed

Harnesses/racing seats are designed to work together with a roll cage. Stock seats and shoulder belts are designed to buckle so you double over in the event of a roll over. A racing harness without a roll bar is more dangerous than a stock setup.

Get a local shop to put in a roll bar.

Of by roll bar you mean the bar behind the seats that the harness straps to. Then yes I am making up the plans to have one put In by my finances dad as he is a master welder. I will then base the rest of my cage around that

Oh I plan to. My brother has been racing stock car since he was 15 so I know how important saftey is. I have all winter to design it. I am designing it around the existing belt system so you can still use the stock 3 point harness

Lol just wanted to see if there were any bolt on options, ( I donor possess the tools nor skill to make one and am not fond of other people touching my rig) the only one I can find is the one from rock hard 4x4 but I don't hear very good things about it lol
