BumpShox Overview Big and Small - BumpShox Protects Them All BumpShox was one of the first to patent the flexible front license plate frame and continues to be an innovator in this segment. You can still see original BumpShox from years ago on cars, a testament to the product's quality and durability. The BumpShox XL is the original front bumper guard license plate frame that doubles as a front bumper protector. Made from a flexible foam that is super strong and resilient. It flexes on impact while cushioning low impact parking bumps with ease. Bigger is better when it comes to bumper protection. That is why the BumpShox XL was designed taller, wider and thicker. At 2.25" inches thick and 14" inches wide it's no lightweight on the street. Aerodynamic design complements any vehicle design. Designed for all weather performance.
