Well i went for a ride today and encountered some not so friendly railroad tracks. Luckily i was only going 5 or 10 miles an hour. My buddy was right in front of me and he made it alright. It seemed like my carbides grabbed the edge of the tracks. I'm running the woody's dooly carbides. Not quite sure if i like them now. If anyone knows where i can get an exact replacement trailing arm please let me know.
