Constructed from durable 1/2 in. thick ultra-high molecular weight (UHMW) polyethylene, the Seizmik? UHMW Skid Plate and Rock Slider Kit provides exceptional protection to the vital components and undercarriage, including the front and rear differentials, as well as abrasion-resistant side panels that serve as rock sliders to protect the rocker panels. Superior strength that’s resistant to denting, gouging and rusting caused by blunt edge impacts or sliding over obstacles. Includes glass-filled nylon frame clamps with brass inserts, that mount in the O.E.M. location, when possible to eliminate excessive drilling during install. 4x thicker, stronger material with more tensile strength than the stock plate.
