MIA's Description

The UnderCover LUX Tonneau Cover is a premium, one-piece bed cover crafted from high-grade ABS plastic, designed to offer exceptional style, security, and durability. Unlike many fiberglass one-piece tonneau covers, the LUX is resistant to cracks and chips. Each tonneau cover is painted in-house by UnderCover to precisely match your pickup's factory paint code, ensuring a flawless match and quick delivery. The cover features a proprietary "X-Effect Infrastructure" which stiffens the tonneau cover, preventing excess deflection and enhancing rigidity, a common issue with other one-piece covers. For cargo protection, the LUX boasts a weatherproof design with a full perimeter seal and wrap-around edges, effectively keeping moisture and dust at bay. Security is addressed with a center twist lock, preventing unauthorized entry. Installation and removal are less intensive than similar one-piece tonneau covers, allowing for quick removal with an extra set of hands when comprehensive bed access is needed. The UnderCover LUX is backed by a limited lifetime structural warranty, with finishes covered for one year.
