NEED Help 2014 Tacoma LIft

Hey so I have a 2014 Tacoma 4wd. I wanted to put a lift and some slightly aggressive tires on it. So I did. I went and got a lift from toytec its the 2.5' kit with aal's I installed my lift and tires did the alignment and every thing looked ok other then the caster on the right side it was a .3 degrees off. That's not my concern. The ride has gone to shit. I know that it would firm up the suspension but not this much. Its to the point where when i go over speed bumps the initial hit is ok but then the rebound is horrible. I need some help. I dont want a truck that rides like a covered wagon. The lift is a spacer that goes in between the spring and the mount. idk if the shocks/struts are too short or what.

 

Thanks man. I was thinking that that could be it. I had a 2008 4runner that i put a daystar spacer kit that sits between the top mount and the tower, it rode great. I am wondering if i should just cut my losses with this and buy that kit. The thing is the rear is doing the same thing.
