were fantastic. For Jeeps they have HD, medium, or light duty springs and they publish the spring lengths and rates. This way you can mix and match and get exactly what you want. I'm not sure if they also offer this for Toyota. However, I do much prefer the old Old Man Emu shocks compared to the new Sport Nitrocharger shocks. But either one is a billion times better than Rough Country.
I don't know anything about Bilstein/Toytec.
