Tacoma sag

My tacoma has the toytec lift, ive wheeled it a few times, trails around my house, and out on the beach, now i noticed everything is fine up front but the bed, the driver side sits about 3/4 of an inch lower then the passenger, i dont understand what happened, any suggestions, any opinions on what to do? its not affecting me driving you can just tell on level ground

 

they make small spacers to make up for the difference. I think they come in two different sizes.

 

links? i also found that my overload spring on both sides was turnin towards the center of the truck, fixed that still no result, do you know what caused it? hit the ground to hard on that one side

 

Well wheelers off road offers the spacer but i have a OME setup not toytec. Its called a trim spacer. It might work for both.
