About APS – Auto Parts Specialist, Inc.

APS (Auto Parts Specialist, Inc.) is a manufacturer rooted in the automotive aftermarket industry, built on a straightforward philosophy: deliver well-engineered, stylish truck accessories that real drivers can count on. Based in Ontario, California, APS has earned a strong reputation among truck and SUV enthusiasts for producing exterior accessories that blend function with form — from side-entry steps to custom-style grilles.

The company operates an ISO 9001-certified manufacturing facility, ensuring that every product rolling off the line meets rigorous quality and consistency standards. That commitment to process-driven manufacturing is reflected in a catalog that spans thousands of SKUs, covering a wide variety of makes, models, and trim levels.

Step Up Your Truck – Nerf Bars & Running Boards

APS is perhaps best known for its extensive lineup of truck steps. Their step nerf bars come in multiple series — including the ST, M3, DS, and Truck Armor lines — offering everything from slim tubular profiles to aggressive drop-step designs. Materials range from 6061 aircraft-grade aluminum to heavy-duty carbon steel, with finishes including polished stainless, brushed aluminum, and durable black powder coat that stands up to road salt, gravel, and daily wear.

For drivers who want a broader stepping surface, APS running boards deliver. The flagship iBoard and iStep series feature a flat, modern profile that departs from the traditional rounded running board — clean lines that complement today's truck styling while offering a full-length, non-slip step surface. These boards are engineered with vehicle-specific direct-fit brackets, making installation a straightforward bolt-on process that requires no drilling on most applications.

Rounding out the step lineup, APS running board steps offer targeted solutions for specific cab configurations, ensuring that mid-size and full-size truck owners alike can find the right fit for their vehicle. All APS step products are backed by a 1-year factory warranty against defects in materials and workmanship.

Front-End Styling – Grilles & Grille Inserts

Beyond steps, APS has deep roots in front-end styling. The brand offers an expansive selection of grilles and grille inserts for trucks, vans, and SUVs — in fact, their grille catalog spans over 2,500 SKUs. Whether you're looking for a bold billet-style replacement grille or a custom mesh insert to refresh your truck's fascia, APS provides options that balance visual impact with straightforward fitment.
