G-991 Clamps for Ford Super Duty Trucks (Set of 6). Made in USA with 6000 Series Structural Aluminum to Ensure Quality and Strength. For Mounting Caps, Camper Shells, Toppers.

I bought these to replace the cheap ones that came with my shell, not disappointed. Top quality, much thicker and they span almost the entire lip of the shell, rather than a single clamp down spot. Great product, worth the investment in my opinion.

These clamps are freakin rock solid. Much better than the standard ones and for six of them 50 bucks is well worth it. I have a lot of anxiety when it comes to towing and hauling items. My camper shell has heavy duty ladder racks and my 2 Native kayaks will be mounted to them when we travel. These clamps eliminate any concern I had about the camper shell getting loose on long trips. The extended upper jaw sits flat and bites perfectly onto the flat part of the shell base. They're just plain rock solid. The old ones sat at a funny angle and looked like they would slip at any moment... even though they never moved I still didn't quite trust the old clamps. I am so glad I spent the extra money and bought these quality clamps and you will be too!!

Great solution when you need a longer clamp for a top.

These clamps are extremely strong and sturdy. Time will tell on its quality

These were exactly what I was looking for. They were exactly as they were promoted.

Easy to install pretty self explanatory. Good design. Works on my 2017 Ford F-250 for a custom rack I built. Have about 2500 miles behind the install and have not had to retighten.

Great clamp.. if you have the F350 or similar super duty and an 8ft bed I would suggest using a total of 8 clamps.. not needed but makes me feel safer and seems more sturdy. However on a 6ft bed this kit is perfect. The best style clamp for the 17 and newer ford super duty I have found. Not sure about the f150 but it looks like they would work good on those as well.

These are the best clamps I have seen.They are designed better than the J hooks.These clamps fit perfectly on my 02 Super Duty with an 02 Snug Top camper.Great Design!!!
