Timbersled has a specific drop bracket just for the Nytro with stock tunnel. It has the same drop as stock. Just weighs a ton less. If you use them with the stock suspension all you're going to do is lose a little weight. Combine them with the Mt. Tamer suspension & you have a great combo & a big weight loss
According to the Timbersled website the sled will sit 2" higher in the back. I haven't installed mine yet, so I don't know if that is because of the drop brackets alone, the suspension arms, or a combination of the two.
