Ive had no problem with tg parts, ever. I know most of the marlin crowd does not like them, but the hard parts have held up really well. I wont use any of their gears or adapters, but the bumpers, skidplate, diff armor, and other misc parts have been good to me.
My buddy's truck has lots of tg parts, f/r lift, tcase 4.7's, 5.29's, and has never had a problem. His truck has done some of the hardest trails here in az and is a daily driver on 37's
