Just know that the rear shocks for a Tundra are NOT direct bolt-on for a 200 like the fronts, so if you get a Tundra "kit" you'll have headaches. Also, the upper arms are different length for a Tundra versus a 200. You'll need to use Tundra lower arms to use those uppers.
Also, if you want to stick with 5100s in the rear, then you'll need to get a set of Bilstein 33-187174. These are for a FJ Cruiser with 2" lift. They have the same diameter lower mounting eye as the 200 and are almost an exact match on length. I would have gone this route but I didn't find out about them until I already ordered my Fox IFPs for the rear.
