Installed on the front driver's side. The metal bent quite a bit before the manifold looked to be on tight enough. Very very easy to install on front driver's side. Has worked great so far.

Worked great easy to install (a lot easier than drilling out broken bolts)..

I wish I had found these a lot sooner. This bracket works 100% and if you buy it you will not be disappointed. I have no exhaust leak anymore so I'm happy. You don't have to take iff the headers, just bolt them in and you are good to go.

The measurements were precise and outcome is performing as promised. The reason for three starts though is because you have to trim the heat shield and the tensioner bolt is longer than necessary.Access to the thermostat is blocked and spark plug is restricted. I would also consider buying a single use packet of high temp sealant if that was bundled with this...

This item is actually a repackaged Dorman 917-142. It even has the dorman logo and part number on it. It requires bending the sheet metal heat shield on the exhaust manifold slightly. I did this by tapping it down a little with a ball peen hammer. Don’t forget to put some lock tight on the clamping bolt, it’s not included. I’ve used these clamps a couple times for an inexpensive quick fix on a customer car and they work well. The factory exhaust manifold gasket is a multi layer steel gasket so it usually is fine and seals up once the repair clamp is installed.

Great product. Easy to install with simple socket set. Got this installed completely in about 15 minutes. Totally worth the time. I had already taken my 2004 avalanche to a reputable muffler shop and they said all they could do was remove the head and drill out the old broken bolt to fix the issue. Googled the issue and found this bracket. Thank you lord! About 10 times less than their estimate to fix it and went on super easy. Very solid bracket, Thick and Coated with a protective coating. Would recommend to anyone looking to fix their exhaust leak. I used this on the front part of the drivers side and it worked great.

There's not a whole lot of literature out there for these ingenious devices. Specifically regarding how well they hold up and if it's truly a "perminent fix" for this common GM problem. I recently bought a used '05 Silverado with a broken right rear exhaust manifold bolt. Others are all rusted and probably will break if I try to remove them. Apparently GM engineers cheeped out and went with weaker bolts. Anyways, I got some quotes from local shops around town and the cost to replace the manifold with these broken bolts was outrageous. Because of the tight working space, they have to be drilled out the bolt from the cylinder head removed from the engine. $150 manifold + $1000 for labor. And that's just one side! Well, my exhaust leak wasn't noticeable to my untrained ear. Gas mileage was normal and no check engine light so the leak must have not been that bad. However, my idle was a bit on the lower side around 500rpms. My understanding is that the idle should be close to 700rpms at operating temp. Well, I gambled on this $30 device and so far, idle has improved to where is should be. Engine seems quieter. Installation isn't "easy" but do-able. Dipstip tube is smack in the middle of where the mounting bolt needs to go in. Its a real pain. You can squeeze a racket on the bolts but its tight. I followed the directions with the proper torque. Im not sure why, but Im sure there is a reason for the specific torque rating by the manufacturer. I hope this hold up for a long time. I bought all 4 devices for both front and rear of each manifold just in case. $120 for a DIY repair is WAY better than $2k plus. This truck has 140k miles on it and I will be tickled to death if its runs another 100k without any exhaust issues thanks to this cheap and ingenious invention.
