I own a set of the a arms in question here, let me clear a few things up.
- You do not have to modify your spindles or get warrior / banshee spindles.
- the pinch bolt adapters are definitely steel, not aluminum
I chose to make a few modifications to mine. Grease fittings, plastic bushings to accomodate grease fittings, and putting a bolt in from the underside of the pinch bolt adapter to lock the ball joint in place.
The only mod I did that I feel like you NEED to do, and should be included in the kit, is the last one on the pinch adapter.
Also some instructions for our less knowledgeable riders might be nice explaining assembly, and use of thread locker in key spots (pinch bolt adapters).
Overall though, for the price I feel like you can't beat this deal. Especially if you ride tight trail like I do and don't want +3 arms.
Also these a arms do move your tires forward 1" also, for some reason they don't advertise that
As for that kids pinch bolt adapter that wore out. Has anyone actually held this worn out piece in their hand and seen that it is made of aluminum? Stuck a magnet to it maybe? I've seen one picture of it and you cant tell what material its made of from there. It very well could have been installed wrong, and that is why these things need some instructions with them, and a locking mechanism for the pinch adapter such as a bolt from the bottom.
Otherwise this thread seems like a flame war between someone trying to defend his product against a group of people that jumped on the hate train that started out with bad info. Just sayin.....
