i run the arb as well and can say it's a good bumper, looks nice,is cheap, and the mod to fit it is very easy. and honestly it's pretty light i was able to lift it and fit by myself. maybe 80lbs or so, (taco version) as far airbags are concerned i don't think they should deploy until you've crumpled the front frame of the truck right? as from my understanding they are not g-sensor but more crumple zone senors, i could be wrong on that, but i do feel that i don't want my airbags going off unless there is going to be server bodily damage a few bumps into things here and there should be alright, lol, i mean after all I've crashed more cars then most people have ever owned.
any ways, i could be wrong but i doubt the other companies tested thier bumpers with airbags as well, that's thousands of thousands of dollars to do a proper study, and i don;t care what you say but running a stress analysis simulations on a cad model is not the same thing as a real world test where you set 'em up and knock 'em down a few times, either way the airbag debate with the arb, is pretty much null and don't think it's an issue even worth considering.
i'm not pushing the arb bumper, but think if your looking to get something done,cheap quick and easy that's your best bet.
the other bumpers are really cool and look slightly better on the body but they are also alot more money for the most part, the OL bumper is looking to be a good one at a fair price, but they just took a massive group order so it'll be interesting to see what sort of lead time develops on that front as well as support down the line if you have any problems, they are a very new company to our little world here but seem to have been doing fab work for years, so they def. know what they are doing but haven't dealt with enough of us for long enough to have a any sort of real consensus. i don't foresee any problems with them though, they are just relatively new to the scene is all.
shrockworks, very pleasing bumper to look at and everyone seems to be happy with theirs, ONCE THEY ACTUALLY GOT IT, and that's the hard part there is that the lead time is quoted straight up without looking at anything 3 months and is likely to be longer also it seems to be the most expensive of the lot. but again very good bumper, they have been around for a while and have earned the rep. " better late then never". you don;t need me telling you this you can do the research yourself and find numerous threads where people gripe and complain about this issue, again nothing wrong with the bumper it's self but with company management/time allocating .
and then you got all of the tube bumpers i won;t comment on those because i have no real interest with tube bumpers, but if you do check out hepar's ride, i usually hate the tube bumpers because it shows to much and makes my good looking 4runner hacked to pieces imo, but the one he has is pretty decent and i think he even had the shop weld in an extra bit of tube ere and there and it really filled the bumper out nicely. basically his doen't look half bad but personally i'd still stick plate bumpers because that's my personal taste in aesthetics.
you can go an a hard core search for a tjm bumper as well, but good luck on that one. and to be honest the retro fitted arb bumpers look better imo
