I cant look at ebay right now since I'm at work. But depending on the price on ebay, I would much rather recommend Wheeler's Off-Road I think they have the extended travel 5100's for a very good price. You should check them out. Actually, I've found that they have better prices for the toytec stuff than toytec themselves. Check them out, I have had excellent service with them, oh and they put candy in the box too!
On a side note, I have the revtek front spacers if you'd be interested in those. Also have the rear spacers too. I cant remember what lift they are, I think 2.5" or something like that. They were on my rig when I bought it, and were the first thing to go. Spacers suck. But they go between the spring and the top plate. Pretty much ruins the ride of the front of the truck. If you are looking at spacers, which I dont think is a good idea, then make sure you get ones that go between the top mount and the strut rather than between the spring and top plate. Check out Wheelers. You wont be disappointed. They have excellent prices for most things. I think I got the front tundra 5100s and toytec springs for less than $400.
Edit: Also, if you aren't that mechanically inclined, then you can have them assemble the struts for you for the cost of labor. I think $100 or something like that. I do all my own work so I can save money for other cool stuff.
