Frequently Asked Questions

What is the difference between running boards and side steps on a truck?

Running boards are long, flat boards that run the full length of the cab and provide a continuous stepping surface for easier entry. Side steps, also called nerf bars or step bars, are round or oval tubes with individual step pads at each door opening. Running boards offer more surface area and are better for families or frequent passengers, while side steps give a sleeker, more streamlined profile. Both are available for crew cab, extended cab, and regular cab trucks from F-150 to Ram 2500/3500.

What is the best type of tonneau cover for a pickup truck?

Soft tri-fold covers are the most affordable and easiest to install, making them a strong choice for everyday cargo protection. Hard folding covers provide better security, weather sealing, and can support weight on top. Retractable covers offer the cleanest look and full bed access when rolled open. The right choice depends on whether you prioritize security, budget, or bed access — browse our Tonneau Covers collection to compare options by truck model and bed size.

Do grille guards or bull bars affect airbag deployment on trucks?

Vehicle-specific grille guards and bull bars from manufacturers like Westin and Go Rhino are engineered to mount to your truck's frame without interfering with airbag sensor calibration. Poorly made or universal-fit bars installed incorrectly can potentially affect crash sensor response. Always choose a fitment designed specifically for your truck and follow the manufacturer's installation instructions.

Are bug deflectors worth it on a truck?

Bug deflectors redirect airflow over the hood and windshield, reducing the amount of bugs, road debris, and small stones that hit your paint and glass. They are especially effective for highway driving and long-distance towing. Low-profile options from AVS and Lund mount flush to the hood for a factory-integrated look while still providing deflection coverage across the full hood width.

Is a hard or soft tonneau cover better for a truck?

Soft tonneau covers are lighter, more affordable, and faster to install — ideal for truck owners who want basic cargo coverage and improved aerodynamics. Hard tonneau covers provide stronger theft deterrence, tighter weather sealing, and can typically hold weight on top for cargo boxes, coolers, or gear bags. If security and weather protection are the priority, go with a hard folding or retractable cover. If budget and ease of use matter more, a soft tri-fold delivers the best value.

Do fender flares help prevent rust on trucks?

Fender flares cover exposed paint and body panels beyond the factory fender edge, reducing chipping and moisture contact from rocks, mud, gravel, and road salt kicked up by wider tires. This is especially critical for Canadian trucks dealing with winter salt, sand, and freeze-thaw cycles that accelerate corrosion. Browse our Fender Flares collection for OE-style and bolt-on fitments for F-150, Silverado, Sierra, Ram, and Super Duty.
