They seem pretty hvy duty, was surprised at what they weighed. Most difficult part of the install was matching up w existing wheel well trim fastener holes. Truck looks great w them on :-)
Pretty easy instructions, use an Exacto Knife to cut out slots on template. Use a Silver Sharpie to transfer hole pattern. Drill both ends of slot with drill bit, & use utility knife to cut the long slots. Only issue was Top Slots on Driver side Template ( see photo), did NOT align/ off by about 3/8”. Had to cut a much larger hole. All the other screws aligned perfectly. Start the Existing Factory screws loosely to start until the are all in.
At first I considered not purchasing these brackets but after completing the installation, the quality and fit convinced me these are worth the price. One word of caution, I discovered the templates are different when printed on my laser printer compared to those sent with the brackets.
