Icon Stage 4 rear lift problems

Hello everyone,

This is my first post because I usually just stalk everyone else's post lol. I just got a full icon stage 4 lift put in and the rear did not lift up enough for me to fit my 33" tires. I had the lift done at the toyota dealership. When I went to talk to the tech about the issue he said that he had adjusted my front shocks so that they would fit my new tires and rims and when he set it down the back end was sagging a lot lower then the front. I did have them install two new steal bumpers from CBI but I don't feel like that should be enough weight to make it sag that much. I will throw some pictures in so you guys can see and let me know what you think. I just ordered a 1.5" rear block and in the summer I will replace it with the full OME leaf package.
