Why it’s a Must-Have Upgrade:

Dual-Purpose Functionality: 

A unique, heavy-duty step and a robust mudflap in one integrated system. The step holds up to 300 lbs, giving you easy access to your truck bed while maintaining the system's structural integrity.

Superior Protection: 

We PROTECT YOUR ASSETS like they're ours. Our solid-mounted system protects your truck's finish and anything you're towing from road debris, rocks, and the elements.

Customizable Fit: 

The system offers 4 inches of adjustability to accommodate various wheel offsets, 24-inch width will cover the tread of your dually application, and the Extra Long Flaps can be trimmed to your desired length.

Easy to Use: 

The system mounts directly to your existing receiver hitch and is easy to remove when not in use.

IMPORTANT FOR ALL DIESEL DUALLY APPLICATIONS: Due to the increased exhaust heat produced by diesel trucks and the wider mud flaps used on dually applications, exhaust heat can damage the mud flap, tread strip, and end cap if a heat shield is not installed.

We highly recommend purchasing and installing our Heat Shield on all dually applications to protect your StepNGuard system from exhaust-related damage.

Damage caused by exhaust heat on vehicles not equipped with a heat shield may not be covered under warranty.
