I can't describe these any other way! They are the monster gussets! 9" long on end, 9" tall, 5" across the curve, 1/4" thick......The gusset that ate Rhode Island......Now you ask, what are they good for? We were looking to be able to reinforce critical areas of roll cages, frames, & crossmembers and these just made sense in some sort of huge way. They come in pairs and may even be good as a shock mount for some of you if you drill them out, you tell me what you want them for, I am going to initially reinforce the rear frame & front crossmember on an FJ40.
