Staff Expert Tip: “The Air Dam on this 20-foot model is a lifesaver for anyone heading up to Saratoga. It doesn’t just block rocks; it drastically reduces the wind blast on your vehicle’s front end, keeping your paint job pristine while you’re cruising at highway speeds.”

What is the purpose of the Air Dam on this trailer? The steel Air Dam (often called a Rock Shield) acts as a heavy-duty barrier between your truck’s tires and your cargo. It deflects stones, salt, and road grime that would otherwise kick up and damage the hood or grille of the vehicle you are hauling.

Why is the 20-foot length better than the standard 18-foot? The extra two feet of deck space allow for better weight distribution of longer vehicles and provide room for a front-mounted winch or extra gear bags without crowding the vehicle. It also improves towing stability by allowing more flexibility in positioning the center of gravity.

How do the Perfogrip ramps help in bad weather? Diamond C’s Perfogrip ramps feature a punched-hole design that provides aggressive traction for your tires. This allows water, mud, and snow to fall through rather than slicking the surface, making loading much safer during rainy spring days or early winter hauls.
