The stock pushrods are fine, but I'm not a big fan of regular plastic pushrods, because they do change length slightly depending on the weather, and will change your trim a little. On my SE, I switched to Sullivan black composite pushrods. They have several different varieties of size and length. The 2-56 X 36 is a direct replacement for what Sig provides in the kit. I have several hundred flights on my SE (at least) and haven't noticed any trim changes using these pushrods.
