Q: What warranty backs the wheels in this package?

A lifetime warranty against structural damage or defects, for the original owner and non-transferable. If a PD wheel cracks or bends in normal use, Unplugged Performance replaces it. The company can stand behind that because the forged monoblock is extremely hard to hurt, which UP says openly. It does not cover cosmetic curb wear or misuse, but the structural promise is what makes this a buy-once package for daily and fleet drivers.
