A roll bar must be 1-3/4 moly or steel. If you go to a cage then you can go 1-5/8. That's one of the tough things about a bar now/cage later. Your not giving up a ton of weight, but if a tech inspector got picky

That true about the bar so I guess if you want a cage
even in the future, do it now and IMO go moly.. if
he were to sell it it would hold value... I have a
full moly chassis in my Rampage but I'm not gonna
go in the 9s so I wont cert it
