I have a 2007 Toyota Tundra (2wd). I am wanting to purchase the toy tec 3/1 leveling kit, but don't know if I should get the rear blocks, or the rear add-a-leaf. Being that it is 2wd, it won't be driven on trails. I just want a more aggressive look. Can anyone help? Has anyone had any complaints about Toy Tec? I was thinking that the aluminum spacer would be better than what most of the leveling kits are made of, so that it wouldn't wear out. Any advice would be greatly appreciated.
