CURT 16418 5th Wheel Installation Brackets Black Select Chevrolet Silverado, GMC Sierra 1500, 2500LD, 2500HD, 3500 **New open box condition. All of my hitches and brackets for sell conditions are quickly verified, and don't guarantee all mounting hardware (bolts, nuts) are included, most have everything but some don't so I don't guarantee it. Please see last pic.** When you purchase a 5th wheel trailer hitch, you expect it to be capable of towing your RV, flatbed or whatever other 5th wheel trailer you own. While a 5th wheel hitch does offer an impressive amount of towing strength, it cannot get far without the proper installation equipment. Engineered for specific makes and models, CURT custom 5th wheel brackets provide the ideal solution for complementing the power of your 5th wheel trailer hitch. A custom 5th wheel bracket features a shape that contours to the frame of your truck and uses pre-drilled holes in the frame wherever possible to make installation quick and easy. In fact, custom brackets are so much easier to install that they can cut installation time in half. Depending on your model of pickup truck, they also reduce or eliminate the need for drilling. These particular custom 5th wheel brackets offer a custom fit for certain Chevrolet Silverado 1500, 2500LD, 2500HD and 3500 or GMC Sierra 1500, 2500LD, 2500HD and 3500 trucks (see application info to verify fitment). Finished in a durable liquid Bonderite coating, CURT custom 5th wheel brackets are made to last. They include all necessary mounting hardware and are designed to be used in conjunction with CURT industry-standard 5th wheel base rails 16104 or 16204 (base rails sold separately).
