Don't waste your money on these, they're way over priced. Let's completely ignore the engineering aspect and assume they're equally strong as the OEM hooks. This is what I used to do for a living (Journeyman Tool & Die maker for many years), so their fancy trade lingo isn't impressive at all.
Two (2) Tow Hooks 3/4" 1018 steel
- Sounds great because it has a number like we're used to hearing for stainless steel and aluminum. However 1018 is about the cheapest mild steel you can buy. This stuff is low-grade, and it WILL rust immediately if it's not painted (or the paint gets chipped).
Two (2) Spacer Blocks 6061 hardened billet
- Here's the really humorous part. The spacer blocks that you don't see, are made of aluminum (6061) so they won't rust. Why not just use more mild steel. They also say they're "hardened billet". Yes 6061 is technically "hard" but it's still aluminum and comes about as hard as it can get. These aren't specially treated chunks of aluminum. The photo looks like they took some bar stock, cut two lengths, and drilled a pair of holes into them. We're talking $15 of materials, and 5 minutes of time on those.
Four (4) Grade 8 Yellow Zinc Bolts & Four (4) Garde 8 Locking Washers
- Okay these are at least decent, though nothing you can't go to the local hardware store and pick up for around $10.
These look like cheap hooks, and that's because they are. I'm not trying to offend anyone who has bought these, or who is considering them. Yes they'll get the job done, but if I was spending $200 on a set of tow hooks, I'd buy the factory set or find some D-Ring hooks before I spent that much on these. I think $100 would be a much more reasonable price for them, but that's just my opinion. Take it for what it's worth (which isn't much).
