5 STARR boat trailers are manufactured using heavy-duty tubular steel for durability. After the steel is machine cut, formed, drilled, punched and welded, all components are hot dipped for a superior corrosion resistant finish. This coating is far superior to the short life of a painted finish. 5 STARR offers a wide selection of models and options making it easy to select a trailer to match your requirements. Unlike welded versions, 5 STARR trailers are fully adjustable to let you custom fit the trailer to your boat and tow vehicle package. A fully articulate roller system eases your boat on and off with precision. You can easily maintain your bearings through the easy-grease axles on our larger trailers for reliability. These large trailers have submersible taillights and use galvanized steel fenders for durability. They don't collapse when you step on them (as long as you weigh less than 500 pounds). What does all this mean to you? Your boat fits like a glove and launches like a dream, and your 5 STARR trailer will last a long time.
