These brackets are great. They're well built, packed in peanuts (For some reason)
First the pros: Overbuilt, prewelded, scale free, Easy to install with some quirks.
Cons: The bracing tab is about 1/4" to low, and hit my radius arms - easy enough to tweak with a grinder though.
The bracing tab is *directly* below the rearmost hole, and if you follow the directions, clamping/drilling as you install them, you can't drill from the bottom. A center punch, drill, and die grinder makes marking/drilling the holes a ~2 hour install job on the ground - likely faster on a lift.
The worst part is the instructions. They're not very clear, mostly in order of operations and placement, but if you take your time and read them 3-4 times, it's simple.
Don't get me wrong, it's not a complicated install - you remove as much of the shackle hangar as needed, clamp the brackets on and drill holes (in the specified order).
I'd give them 4.5 stars, but it's not an option, so I'll drop 5 stars instead.
