Putco Denominator Modular Tow Hook Light Bar Mount (19-26 Sierra 1500)Find parts that fit my vehicle

The Putco Denominator™ is a modular, vehicle-specific front bumper light bar mount system for trucks and SUVs that need a clean, secure installation with no modification. Designed as a precision-fit truck tow hook clamp kit, it matches factory tow hook geometry for a secure, quick-install platform for auxiliary lighting.

Unlike universal adjustable bumper mounts, Denominator aligns with specific tow hook profiles for proper positioning, reduced vibration, and increased long-term durability. Installation is simple with an easy, no-cut, no-drill off-road light bar bracket installation design that preserves the truck’s front-end structure. Positioned at the grille and tow hook area, Denominator serves as a secure light mount for grille lights, perfect for night visibility. It supports work truck LED lighting, utility truck lighting brackets, and fleet vehicle lighting solutions while providing an ADAS-friendly platform for real-world use.

The optional step mount adds safety, accessibility, and utility. It doubles as a functional front step, making it easier to access the engine bay, windshield, and roof rack. Acorn nuts provide traction, and the step is rated for up to 350 pounds each, ensuring dependable strength. Built for harsh environments, Denominator is ideal as service truck light support, mining truck auxiliary visibility, and an overland expedition mounting solution. Whether outfitting a fleet vehicle, work truck, or adventure build, it delivers precise fitment, functional utility, and durable performance beyond illumination.
