GGC SMS Auto Parts Co Roof Rack Accessory

GGC SMS Auto Parts Co: Roof Rack Accessories Built for the Overland Trail

When it comes to roof rack accessories, few manufacturers bring the same combination of heritage, American craftsmanship, and purpose-built engineering as GGC SMS Auto Parts Co. Founded in 1946 by the Schafer family in the Philadelphia area, SMS Auto Parts has spent decades perfecting the art of precision-built automotive components — and their Exposed Racks (EXR) line represents the pinnacle of that legacy applied to the modern overlanding world.

The EXR Lineup: Purpose-Built Roof Rack Accessories

At the heart of SMS Auto Parts' roof rack accessory catalog is the EXR platform — a family of no-drill crossbar systems designed specifically for Jeep Wrangler (JL, JLU, JK) and Jeep Gladiator (JT) owners. The EXR system uses a patented Click-In mechanism that allows load bars, roof top tents, kayak mounts, bike carriers, and storage bins to mount and dismount in seconds — no tools, no headaches.

One of the brand's most notable achievements is their invention of soft-top roof rack systems that fit under the factory soft top, as well as a patented weight distribution system that spreads load evenly across the vehicle's roof structure — a feature that sets SMS apart from generic aftermarket alternatives.

Materials & Construction That Handle the Elements

SMS Auto Parts does not cut corners on materials. Their EXR crossbars are constructed from heavy-duty carbon steel, then electroplated and acid-washed for added structural strength. A final black powder-coat finish is applied for robust protection against rust, dust, and corrosion — ensuring these roof rack accessories hold up through harsh weather and demanding off-road environments. Every product is backed by a 3-year warranty and is proudly manufactured in the USA.
