CMS/ADAS Compatibility

Built for today’s ADAS-equipped trucks, every GOSS grille guard is engineered to mount without blocking the front-facing radar, cameras, and sensors behind your bumper. That means collision mitigation, adaptive cruise control, and lane-departure warnings keep working exactly as the factory intended. Our CMS/ADAS-compatible design protects systems like Bendix Fusion and Detroit Assurance with no fault codes or dashboard alerts — so you get heavy-duty front-end protection without sacrificing a single driver-assist feature.

Lift Assist System

Our built-in Lift Assist System uses heavy-duty gas shocks that let the grille guard tilt away effortlessly, opening full hood and engine access in seconds. Daily pre-trip inspections, oil changes, and routine maintenance become a quick one-person job — no tools, no heavy lifting, and no removing the guard. The gas struts hold everything open safely, so your truck spends less time in the shop and more time on the road.

Machined Brackets

Every GOSS mounting bracket is machined from solid steel, not bent or stamped like the competition — delivering the most precise, secure fit to your truck's frame. That rock-solid connection eliminates the vibrations, rattles, and stress cracks that cause bracket failures in the field, so your grille guard stays tight and true mile after mile of hard-working duty.

1/2" Steel Plate Build

Where other guards rely on simple tubing, GOSS is engineered around two 1/2" steel-plate impact boxes — a full half-inch of solid steel at each mounting point. Concentrating that mass exactly where impacts hit delivers maximum protection and structural rigidity right where it matters most, giving you an optimally balanced build that shrugs off road debris, wildlife strikes, and vehicle collisions.

Grade 8 Hardware & Towing Access

A grille guard is only as strong as its weakest link. Thats why GOSS fastens everything with Grade 8 hardware, the toughest, highest-tensile bolts available. Where others cut corners with cheap fasteners that loosen and shear, our Grade 8 bolts keep your guard locked-in tight through every mile. — No tow hooks, no problem! Add our optional eyebolt kit and you get a built-in tow and recovery point. Hook up, winch, and pull without ever removing the guard.

Corrosion Resistance

Every GOSS guard is finished with a seven-layer epoxy paint system that seals out road salt, moisture, and grime for a deep, lasting shine. That coating clears over 1,000 hours of ASTM salt-spray chamber testing — the equivalent of roughly five years of corrosion-free service, depending on your climate and road conditions. Rust stays out, so your grille guard keeps looking factory-fresh season after season.

Integrated Locking Mechanism

For extra peace of mind, GOSS builds in an integrated locking mechanism that secures the guard in place — blocking the hood from swinging out past it whenever your truck sits parked or idle for long stretches, guarding against tampering during downtime. For everyday driving, a quick-release latch keeps the guard unlocked and freely accessible on the go, so hood and engine access stays fast and tool-free the moment you need it.
