Collection: Body Armor & Rock Rails

Defend your vehicle's vulnerable rocker panels from crushing boulder impacts, eliminate costly door-jamming panel deformation loops on tight trails, and establish a rugged pivot point for extreme technical maneuvering with our selection in the Body Armor - Rock Rails collection. At DIY Customs, we provide high-tensile DOM steel rock sliders, dual-purpose step-integrated nerf bars, heavy-wall trail rails, and frame-reinforcing gussets engineered to deliver a seamless and perfect fit alongside your chassis.

Whether you are packaging a rugged, high-clearance protection layout to shield lower sheet metal safely away from custom wiring arrays and high-amp fuel pumps on an off-road overland travel vehicle, outfitting your custom shop garage workspace configuration with industrial-strength side armor to fleet-maintain hardworking commercial service trucks and utility rigs, or building a high-velocity rock crawler for extreme trail parameters, our professional-grade side rails ensure maximum material density and structural safety metrics. From raw layout weld-on kits to direct-bolt frame plates configured for popular domestic and import truck, Jeep, and SUV frameworks, we carry the ultimate rocker panel preservation essentials.
