Air Lowering Kit

I am unfortunately looking for some sort of kit that could lower my stock '09 Tacoma Dual Can Prerunner several inches so my wife can get into the truck (recent medical issue) and then I could raise it back to normal height and drive off. I'm thinking an air suspension would work but I have no idea and doing a Google search shows a few things but nothing looked like what I need.

I have no desire to drive the truck while in it's lowered state however if it doesn't mess with wheel alignments and clearance issues then it would be nice to have that option of having it lower so I don't have to lower, raise, lower, raise, etc... all the time.

I would prefer a bolt-on replacement, no cutting or major modifications as I'm not equipped to do that sort of work.

Thanks,
Joe
