The problem is the link between the outside door handle and the latch. All you have to do is make it a little bit longer by taking some of the two beds out a bit. It needs to be about a mm or 2 longer than it is.

From what I have experienced with KFI so far, they drastically lack foresight. I have their winch mount and poly plow. The winch mount is fine. The plow is mostly fine but has many things that could be better
I like how that one doesn't connect to the bed hinge like most of the others. And I can see what you mean about the exhaust being close to the light. Hopefully it doesn't cause any problems
Give a Cornell Customs primary spring a try. It will most likely do what you are looking for. Less than $100. Easy to put in. Easy to take out if you have warranty issues come up.
It lowers your rpms as well
