from that pic, your upper arm is definately not hitting the upper bag plate...looks liek you dont even have upper gussets and just lowers, nothing wrong with that since your lower gussets are past the half way point on the upper bag plate, enough support.
take the wheel off and get a shot of it that way. and like they said take a pic of it aired up
did you cut the shock tower off? i dont see it, but it could be caught under the upper arm so it wont let you lift.
take more pics...that shot doesn't really show us anything. show clear shots of the components.
your bag placement looks fine to me, as long as the bag is compressed all the way when you're laid out it'll give you the lift. and since your bag is really close to the frame and you dont have upper gussets, the arm will not hit the upper bag mount until a lot later. you should be getting as much lift as Robbie is getting
