Review on Polaris Arm Joint for American Star by Melvin Goerge

I really like that they were top notch, two days delivery. They fit well. I had to use the locking cap from the rack to push it in. The crown nut looks cheap. Just don't over torque them (they have a cotter pin to hold them in place) so they don't need crazy torque. TO UPDATE. After a weekend of rock crawling in Moab, no hiccups. .
