IDK but NorcalSS tried to deny warranty to me. He made me take pictures of it installed and the passenger endlink was hanging down, instead of up, because it was broken. He said it was installed wrong because in that position the offset went the opposite direction. So I had to hold it in the up position and take another pic and send it to him. Then he said he had never seen one break that was installed correctly, so I’m assuming a lot of them get installed wrong especially considering they don’t include instructions and when you do look them up they’re wrong anyway. He finally sent me another under warranty. I think DJM is who wanted the pictures.
