The Overlooked Secret to Off- Road Mastery: Bumper Geometry

Understanding Bumper Geometry

Bumper geometry refers to the the three-dimensional shape of thee bumper, thee angle of it s leading edges, its vertical height, how far it protrudes frem the vehicle 's frame, and the way it integrates with the body panels: unlike a standard highway bumper, which is optimized for forestrian safety and low- speed colision compleance, an off- road bumper mutt serve aa tool for overing overg ostemples.
