The road to Chaco Canyon Vs. Bilstien 5100's

I finally got a call back from Bilstien after leaving a 2 messages 2 days ago. I explained what happened and under what conditions and basically they said it is not covered under warranty. The reason because I was going too slow (8 to 12 mph) over a wash boarded road which caused the over heating and meltdown of the front shocks. She even stated that they have seen it happen before. The 5100 series shocks I have are for trucks with 0 to 2 inches of lift. My truck is not lifted so I have the correct shocks for my truck. So not all 5100 bilstiens are for lifted trucks. She also said that I would need to talk to a tech at bilstein to get the correct shock for my application. I then asked her should I not trust the people that sell your products? She then told me I would have to take it up with the people that I bought them from. I think I know where that's going to lead. I think I will just cut my losses and try another brand of shock.
