Review on 🔧 CURT 16411 5th Wheel Installation Brackets for Chevrolet Silverado & GMC Sierra 2500, 3500 HD (excluding Cab & Chassis) by Chris Tardy

If suitable. Remove spare part. Remove the heat shield. Position the brackets so the rear holes are closer to the center of the truck (the rear rack studs are further away). You can access all of the rail studs from the back of the truck. The rail bolts are 110 ft/lb and some cannot be loosened with a torque wrench. A private key with a cheat bar is used. First, I practiced the "feel" of the bolts tightened with a torque wrench. The rail studs above the gas tank are accessible from the back of the truck. Used both sets of screws on truck tracks. They are easy to tighten using the rear wheel as a lever. For a larger set, place a 2x6 piece of wood on top of the hoop to maintain the expansion plane. Replace heat shield and replacement. Use black spray paint on the screws for a better look. Total time 4 hours. I did it myself, I'm not a mechanic. Have a friend hold the rail studs while you install the fastener and nut since you will be pushing on the stud. Without friends? Use tape to prevent the head of the rail bolt from rising.
