Fitment of donated suspension

Hi All, first post on here.

I bought an 05 DC back in January, it was almost entirely stock and has left me lots of room to grow. I have a friend who recently upgraded his suspension on his 98 tacoma AC, giving me the parts he replaced. It looks like its just a standard 5100 kit, but I am needing some help on if this is something that would fit such a heavier truck. If this does fit, would it be something that I could I install myself? Going down this route would open up some additional options on tire and wheel upgrades, but I am also fairly clueless on that. I do a fair bit of offroading for fly fishing, rafting, and camping. Any advice would be great. Pictures of the kit are attached below!

 

Not 100% sure about the front struts, but those rear shocks aren't going to work. The top mount is different.

**I haven't done any research and am going from memory.** But the fronts might work. I seem to remember people using 1ts gen tundra bilsteins on their 4runners as an option, but I would recommend checking the extended and collapsed link of the shocks. You'll want to keep your springs on your coilovers. Also know that the valving will probably be for a lighter 4 or 6 cylinder engine and not the heavy V-8 and weight of a DC tundra. You might be better off selling those and getting something for your truck. But you can always try it for science.
