You guys got me curious on this, so I went and checked. Mine is an Alumistinger made from Anderson MFG, V5 rated. It's a solid block of aluminum cut out-no welds, just one solid piece. Rated at 15,000 lbs. and 2000 lbs. tongue rating, 6" drop. I've never looked for them again, so I don't know if they're even still made. No idea now what I paid back then for it-again, it was all they had in stock. I'd have bought a solid bar stock steel one if they had it, but this is all that was there at the time, and I needed to pull the trailer that day, so I bought what was on the shelf. It's been working great and shows no signs at all of wear and tear. Then again though, with the slow fatigue failure-could you ever really see it??? Milled out of a solid block though like this one is, and rated that heavy, I'm kind of inclined to think maybe this was meant to last. And, there are different grades of aluminum as well-no idea what they are or what they mean, but in this application, I wonder if the different alloys used are a different structural compound to help avoid this issue?
I see what you're saying about the elasticity and bend back. A few companies make aluminum track bars and such for Jeeps, but I'd personally be leary of running one myself-for that reason, among others. I'll stick with my Currie unit thanks. Wow-kind of getting side tracked a bit. Sorry about that!
Best of Luck,
Mike
