Hey everyone!
This is the co-owner and vp of Andersen Flaps to answer the question on whether our eco-flaps crack in the winter.
If they crack in sub zero temperatures, that is a material defect and is covered under our 1 year manufacturer's warranty.
Eco-flaps are made from a high impact, extremely tough nylon - they are tougher than any mud flap on the market. We have customers spending less to replace flaps because ours are so durable (among the other two benefits of spray reduction and fuel savings)!
They have been used in North America and Canada in the winter for over 2 years now.
If any are cracking in the winter, someone better be letting me know! Now this doesn't include you guys backing over them or road hazards which no mud flap can withstand.
So, howdy to you all and keep on truckin with the eco-flaps!!
Rosemary Andersen, Andersen Flaps
